The study: https://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2024.1360687/full

Background

Dementia, particularly Alzheimer’s disease (AD), which constitutes 60% to 80% of cases, is becoming increasingly common due to the aging population, with projections indicating up to 152 million affected individuals by 2050.

Alzheimer’s is marked by a gradual decline in cognitive functions, including memory loss, language deterioration, and changes in personality and mood, making its prevention and treatment a global challenge. There is a pressing need for biological markers that can aid in early diagnosis, differentiate between types of dementia, and predict disease outcomes.

Aging, as the primary risk factor for AD, brings about physiological degradation and increases susceptibility to various conditions, including neurodegenerative disorders. Research suggests that aging contributes to AD through the accumulation of senescent cells which promote pathological changes by releasing inflammatory factors.

Recent advancements in the study of AD focus on the immune system’s role in its progression, particularly the involvement of Tau protein and T cells, including cytotoxic T cells observed in affected brain areas.

Techniques like single-cell RNA sequencing (scRNA-seq) and T cell receptor (TCR) sequencing (scTCR-seq) have linked CD8 T cells to age-related AD progression. The integration of multi-omics approaches provides a comprehensive molecular insight, enhancing understanding of AD pathogenesis and helping to identify potential biomarkers.

Furthermore, studies have shown natural killer (NK) cells play a crucial role in the immune surveillance of aging. They help mitigate inflammation, clear harmful proteins and damaged neurons, and are pivotal in managing inflammation and protein accumulation in the brain. This has led to clinical trials exploring NK cell therapies in AD patients, showing promising results in stabilizing or improving patient conditions.

Hence, there’s an ongoing effort to delve deeper into the role of NK cells in aging and AD, leveraging biomarkers for early diagnosis and potentially curative treatments, alongside exploring the developmental trajectories of NK cells across different age groups through advanced genetic and cellular analysis.

Gaps in Alzheimer’s Genetic Research

Genetic studies on AD have provided significant insights but also face several critical gaps that hinder a fuller understanding and more effective treatment strategies. Here are some of the main gaps in current genetic studies of Alzheimer’s:

Limited Genetic Diversity

Only a few genetic research studies on Alzheimer’s has been conducted on populations of European descent. This limits the applicability of findings to global populations, particularly given the genetic, environmental, and lifestyle variations across different racial/ethnic groups. More studies involving diverse populations are essential to uncover relevant genetic markers and risk factors specific to various ancestries.

Complex Genetic Interactions

Alzheimer’s disease is influenced by multiple genes, and the interactions between these genes can be complex. Current studies often fail to fully capture the interplay between genetic factors and how they contribute to disease risk, progression, and response to treatment.

Polygenic Risk Factors

While significant progress has been made in identifying major genes associated with Alzheimer’s, such as APOE ε4, many other genetic factors likely contribute to the disease in a polygenic manner. Other less known genes and their variants often have small individual effects that are difficult to detect with current study designs and sample sizes.

Integration with Environmental and Lifestyle Factors

There is a need for better integration of genetic data with environmental and lifestyle factors. Alzheimer’s disease is influenced by a complex interaction of genetic predispositions with factors such as diet, physical activity, exposure to toxins, and other lifestyle choices. Few studies comprehensively integrate these aspects to provide a holistic view of risk and progression.

Epigenetic Factors

Epigenetics plays a crucial role in gene expression without altering the DNA sequence. Changes in epigenetic patterns can significantly impact the development and progression of Alzheimer’s, yet this area remains underexplored compared to direct genetic studies.

Rare Variants

Current studies often focus on common genetic variants with minor effects. Rare variants might have significant impacts on disease risk and manifestation but are challenging to detect without large sample sizes or specialized study designs.

Results of the Study

NK cells, known for their dual functions in cytotoxicity and immune regulation, play a crucial role in managing infections, malignant tumors, and senescent cells (old or dying cells).

Interestingly, while the number of these cells increases with age, their functionality declines, potentially due to decreased cytokine (protein-based immune signaling molecules) secretion and cell toxicity. This study suggests that senescent cells activate immune responses, and the NK cells respond by eliminating these cells through direct killing or secretion of cytokines.

Further, through Mendelian randomization (MR) analysis based on a cell trajectory model developed from different age groups, the study points to CHD6 as a potential gene influencing AD. CHD6, involved in DNA damage response and chromatin remodeling, is speculated to affect transcriptional activities linked to AD progression.

How the Study Addresses Gaps in AD Research

By focusing on the role of NK cells, which increase in number but decrease in functionality with age, the study enhances the understanding of the immune system’s involvement in AD. This addresses the complex interplay between genetics and the immune system, showing how genetic predispositions can influence immune responses, potentially leading to AD progression or influencing its severity. This insight into immune-genetic interactions is crucial for developing targeted therapies that can modulate immune functions in AD.

Furthermore, the research uses advanced techniques like single-cell RNA sequencing and Mendelian randomization to investigate the role of specific genes like CHD6 in the context of AD, bridging the gap between genetic predispositions and cellular behavior. This methodological approach helps in pinpointing specific genetic pathways that contribute to AD, beyond the common genetic markers like APOE ε4.

This studyprovides a more nuanced understanding of how aging-related genetic changes impact cellular functions and disease progression, potentially leading to the identification of new therapeutic targets and personalized treatment strategies based on an individual’s genetic and cellular profile. This aligns with the need for pharmacogenomic studies in AD, aiming to tailor treatments to genetic and cellular characteristics that may vary from one individual to another.

Possible Drawbacks of the Study

Despite the insightful findings, the study faces several limitations such as data derived solely from peripheral blood mononuclear cells. These cells may not fully represent the cellular or molecular processes occurring in other tissues, especially in diseases primarily affecting specific organs or systems, like AD.

Further, the study relied on single-cell analysis from an Asian population, and the use of GWAS data from a European cohort.

These factors could affect the generalizability and reliability of the findings. To overcome these limitations, further studies involving larger and more diverse populations are recommended, alongside continued exploration of the underlying mechanisms and potential therapeutic targets in AD.

Understanding 23andMe’s New Historical Matches Feature

Date of Content: April 24, 2024
Written by: Avanthika Nityanand
Reviewed by: Maarit Tiirikainen, PhD

23andMe has a new premium feature in their service that can reveal whether individuals are genetically related to historical figures. 23andMe’s new Historical Matches feature includes famous names such as Ludwig Van Beethoven. It also includes historically significant profiles such as a high-status Viking woman from the 9th century, an African female hunter-gatherer, or a Caquetio man from Curaçao dating back to pre-colonial times. 23andMe analyzes DNA to identify potential links between present-day individuals and their ancestors, offering insights into personal and human history. This scientific process helps individuals understand their ancestry by connecting them with past cultures and populations.

This new feature is available through its 23andMe+ Premium service. This feature allows users to identify potential genetic links to 335 historical figures by finding identical DNA segments that suggest a shared ancestor. The aim is to give users a method to trace connections to their historical lineage.

The company plans to expand the feature by adding more historical genomes. It will provide users with additional opportunities to explore their connections to history.

Dan Chu, Chief Product Officer at 23andMe, stated that “Historical Matches” represents a significant advancement in detecting genetic connections between modern individuals and historical figures. The feature uses peer-reviewed scientific methods and in-depth data analysis.

23andMe is the first prominent DNA ancestry service to offer genetic matching at this level with historical figures.

How does 23andMe Match to Historical Figures?

Research by Harvard population geneticist David Reich and Svante Pääbo, a Nobel Prize winner at the Max Planck Institute for Evolutionary Anthropology, has contributed to understanding ancient human populations, migration patterns, and the relationship between Neanderthals and modern humans. Their work has challenged traditional views on human history and migration and also provided insights into disease origins that may lead to new treatments.

23andMe’s Historical Matches feature extends beyond traditional ancestry tests that trace maternal or paternal lines. This new feature scans the entire genome to find identical DNA segments that link members to historical figures who lived hundreds or even thousands of years ago.

The process uses publicly available data, scientific research, and 23andMe’s relative-matching technology to establish these connections. Like the DNA Relatives feature, Historical Matches identifies potential links by finding shared DNA segments between 23andMe+ Premium members and historical figures. The system sets quality thresholds for the length of a shared DNA segment to minimize the likelihood of incorrect matches.

Members with a 23andMe+ Premium subscription may find that they have a connection to at least one historical figure, though, per 23andMe, these connections are generally distant. In some cases, the matches may indicate closer relationships.

Which Historical Figures Are Included?

The genomes included in 23andMe’s Historical Matches feature vary widely in age; some are from individuals who lived thousands of years ago, while others date back just a few centuries. Most remain anonymous, with notable exceptions such as Ludwig van Beethoven, who passed away in 1827.

The feature provides detailed reports on each historical individual, covering aspects of their lives, how they died, and the historical context of their times, including any artifacts found with them.

Beethoven’s genetic predispositions have been explored through DNA extracted from a lock of his hair. In 2023, researchers from the University of Cambridge and the Max Planck Institute published a study analyzing Beethoven’s genome to investigate his health issues, including hearing loss, liver disease, and gastrointestinal problems.

That same year, researchers from Harvard, the Smithsonian, and 23andMe analyzed the DNA of 27 African Americans, both enslaved and freed, who worked at a Maryland iron furnace during the American Revolution and the 19th century. Published in the journal Science, the study unveils the overlooked history of these individuals. It sets the ethical and technical benchmark for studying such burial sites. Of these, the genomes of nine individuals were well-preserved, though their names are lost. The study provides insights into the harsh and often brutal conditions they endured.

Overall, the Historical Matches feature includes 335 historical figures, mostly anonymous. These individuals are grouped into different historical categories based on the original published studies, providing a narrative of their lives and times.

Which Historical Groups Are Included?

The Viking Age

During the 8th to 11th centuries, known as the Viking Age, seafaring people from Scandinavia traveled extensively, establishing settlements and trading across Europe and the North Atlantic.

Catoctin Furnace Ironworkers

The Catoctin Furnace Iron Workers consisted of enslaved and freed African American laborers who worked at one of the earliest industrial sites in the United States during the 18th and 19th centuries. This furnace produced iron goods, including artillery used during the siege of Yorktown and supplies for the Continental Army.

Iron Age Taiwan

In Taiwan, the Iron Age was when the indigenous Atayal people began utilizing metals, such as bronze, iron, and silver, for their tools and artifacts.

The Ancient Eurasian Steppe

The Eurasian Steppe is a vast expanse of grasslands extending from modern-day Hungary and Romania to Mongolia and China. It served as a significant route for human migration and played a crucial role in spreading the Indo-European languages.

The First Peoples of the Caribbean

This group includes the indigenous communities that inhabited the Caribbean region from around 1000 BC until the arrival of Spanish explorers in 1500 CE.

The Genomic Formation of South and Central Asia

Contemporary South Asian populations are primarily descendants of a mix of two ancient groups known as “Ancestral South Indians” and “Ancestral North Indians.” Ancestral South Indians emerged from an admixture of ancient Iranian farmers and southern Asian hunter-gatherers around 2000 BCE. Ancestral North Indians originated from pastoralists who inhabited the eastern Eurasian Steppe during the Bronze Age.

Late Stone Age and Iron Age South Africa

While Southern Africa is renowned for sites associated with early human ancestors dating back hundreds of thousands of years, it also has sites from more recent periods. The Late Stone Age has no definitive end date in this region. However, the Iron Age began around 200 CE with the arrival of Bantu-speaking peoples skilled in ironworking.

Ancient Northern Chinese Millet Farmers

The area between the Yellow River and the West Liao River hosted some of the world’s earliest complex agricultural societies, which cultivated millet. This cultivation and subsequent human migrations from the region helped establish millet as the staple crop of Northeast Asia nearly 8,000 years ago.

The Ancient City of Beirut

Beirut, Lebanon, has been continuously inhabited for over 5,000 years and was controlled by various empires including Assyrian, Babylonian, Persian, Greek, Roman, Byzantine, Arab, and Ottoman. Each left a cultural but not always genetic legacy.

Is the 23andMe Historical Matches Worth It?

Several users on the Reddit forum have voiced a positive opinion on this new feature.

A user who goes by the handle ThePikminLord found the closest match with a Norse woman from Greenland, with more shared DNA than 74% of users and another with an infant girl from the Faroe Islands, with shared DNA greater than that of 71% of 23andMe users

The user Icy-You9222 reported approximately seven matches, with three from Denmark, two from Sweden, one from Estonia, and one from Ukraine. The highest percentage of shared DNA was with a young woman from Denmark, at 0.10%. As a Black American female, her Ancestry DNA results showed about 5% Swedish and Danish heritage and 1% Norwegian, while 23andMe reported 2.6% Scandinavian ancestry. She noted that these results seem consistent with her ancient Viking ancestry and expressed enjoyment in learning about her genetic background.

LifeDNA Aging Report: A Walkthrough

Date of Content: April 21, 2024
Written by: Avanthika Nityanand
Reviewed by: Maarit Tiirikainen, PhD

This is a LifeDNA Premium Report.

Aging is a natural and complex process involving gradual physiological and biological changes in an organism over time. This process affects individuals on a cellular, molecular, and organ system level. It leads to the eventual decline in physical and mental capacities and increased susceptibility towards certain conditions and the end of an individual’s lifespan.

Biological markers of aging include:

deterioration of cellular functions
loss of telomere length
accumulation of metabolic waste products
decreased regenerative capacity of stem cells

While aging is a universal process observed across different species, the rate and impact of aging can vary significantly due to genetic, environmental, and lifestyle factors.

How Aging Works

Aging works through several mechanisms that impact the body on a cellular and molecular level. One primary aspect is the accumulation of cellular damage over time, which includes DNA mutations and oxidative stress caused by free radicals.

Additionally, telomeres—the protective caps at the ends of chromosomes—shorten with each cell division, leading to cellular aging and dysfunction. Hormonal changes also play a critical role, particularly the decrease in hormones like estrogen and testosterone, which affect various body systems.

Moreover, the decline in cellular autophagy (a process by which cells clean out damaged components) and increased inflammatory responses contribute to the aging process. These changes collectively lead to the typical signs of aging, such as wrinkles, decreased mobility, and impaired cognitive functions.

LifeDNA Aging Report

The LifeDNA Aging Genetic Report analyzes genetic markers that influence the some of the aging processes and related outcomes. Here’s a general overview of the traits covered in the report and how understanding the genetics can be beneficial:

Age-related Hearing Loss

Age-related hearing loss, also known as presbycusis, is the gradual loss of hearing that occurs as people get older. This condition typically affects both ears and results from changes in the inner ear, auditory nerve, and other structures. Contributing factors include long-term exposure to loud noises, genetics, and changes in blood supply to the ear due to heart disease or high blood pressure. Hearing loss can impact speech understanding, particularly in noisy environments, and often high-pitched sounds are lost first. Genes like SIK3 have been shown to influence this trait.

Age-related Muscle Mass Loss

Age-related muscle mass loss, or sarcopenia, involves the progressive loss of skeletal muscle mass and strength beginning as early as the 30s or 40s. This decline can contribute to weakness, decreased stamina, and an increased risk of falls and fractures. Sarcopenia is driven by factors such as hormonal changes, reduced physical activity, changes in protein synthesis, muscle regeneration, and genetics. Genes like VDR and ACTN3 have been shown to be associated with this trait.

Eyelid Sagging

Eyelid sagging, in the forms of dermatochalasis or ptosis, refers to the drooping or sagging of the upper eyelid that often occurs with age. This can be due to the weakening of the muscles that raise the eyelid (ptosis) or degeneration of the skin and soft tissue around the eyes (dermatochalasis). Eyelid sagging can impair vision if the eyelid falls low enough to cover the pupil. A 2018 GWAS identified several new genes, like MACROH2A2 (or H2AFY2), that were shown to be significantly associated with eyelid sagging.

Age-related Physical Function Impairment

Age-related physical function impairment encompasses a decline in the ability to perform daily tasks and movements effectively, such as walking, balancing, and handling objects. This impairment results from a combination of factors including muscle weakness, joint problems, neurological decline, cardiovascular limitations, and genetics. Genes like ACTN3 and UCP2 have been shown to be associated with this trait.

Risk of Repeated Falls

As people age, they face an increased risk of repeated falls due to factors such as reduced muscle strength, balance disturbances, visual impairments, and slower reaction times. Falls are a major concern in the elderly, leading to injuries like fractures and head trauma, which can significantly impair mobility and independence. Genes like FHIT have been shown to be associated with this trait.

Vascular Aging

Vascular aging refers to the changes in the vascular system as we age, including stiffening of the arteries and reduced efficiency of blood vessels. These changes increase the risk of cardiovascular conditions such as hypertension, stroke, and heart attacks. Factors like smoking, high cholesterol, and diabetes can exacerbate vascular aging. A 2022 GWAS uncovered nearly 60 significant genes associated with this trait.

Age-related Bone Loss

Age-related bone loss, or osteoporosis, is the thinning of bone tissue and loss of bone density over time. As bones become less dense, they weaken and are more likely to fracture. This process is accelerated in women after menopause due to a drop in estrogen levels, a critical factor in bone density and health. Studies have shown that genes like ALDH7A1 significantly influence the risk for osteoporosis. The ALDH7A1 gene codes for a protein that breaks down and detoxifies acetaldehyde—a substance that disrupts the growth of osteoblasts (young bone cells) and reduces bone formation.

Age-related Cognitive Decline

Age-related cognitive decline is the gradual decrease in cognitive functioning that includes memory, thinking, and reasoning skills. While not all older adults experience significant cognitive decline, many will notice slower processing speeds and difficulties with multitasking, learning new skills, and remembering information. Studies have shown that the APOE region is significantly associated with cognitive aging. The LifeDNA Aging report covers many more such markers.

Age-related Muscle Weakness

Age-related muscle weakness is a decrease in muscle strength that accompanies aging and is often associated with sarcopenia. It results from a reduction in muscle fiber quantity and quality, impacting an individual’s ability to perform physical tasks and maintain independence. Genetic variation in genes like SLC39A8 have been shown to influence this trait.

Age-related Verbal Memory Decline

Age-related verbal memory decline involves the deterioration of memory functions, characterized by difficulties in recalling names, appointments, and recent events. This type of memory loss is considered a normal part of aging, distinct from the memory impairments seen in dementia and Alzheimer’s disease. A first-of-its-kind large genetic study in 2017 found significant associations between genes like APOE and memory-related parameters like immediate recall.

Hair Graying

Hair graying is a common sign of aging caused by the gradual loss of pigment cells (melanocytes) in hair follicles. This results in hair turning gray and eventually white as pigment production decreases. Genes like IRF4 have been shown to influence this trait.

Healthy Aging

Healthy aging refers to the process of developing and maintaining the functional ability that enables well-being in older age. This concept emphasizes optimizing opportunities for physical, social, and mental health to extend life expectancy and improve the quality of life as individuals age. Factors that promote healthy aging include a balanced diet, regular physical activity, social connections, and effective management of health conditions. Genes like LRP1B have been shown to be associated with this trait.

Can Aging Be Stopped?

Currently, aging cannot be completely stopped as it is an inevitable biological process driven by complex genetic and environmental interactions. However, significant research is focused on understanding and potentially modifying the mechanisms of aging to extend the health span, the period of life spent in good health.

While it’s unlikely that the aging process can be completely halted, interventions such as gene therapy, caloric restriction, and advanced medical treatments may potentially delay the onset of age-related diseases and extend overall lifespan.

The field of gerontology continues to explore these possibilities, aiming to break down the biological barriers of aging.

Can Aging from Stress Be Reversed?

Aging accelerated by stress, often referred to as “stress aging,” can be partially reversed or mitigated. Chronic stress leads to increased production of cortisol, a hormone that, in high levels over prolonged periods, can have detrimental effects on the body, including accelerating aging processes. Managing stress through techniques such as mindfulness, meditation, regular physical activity, and proper sleep can significantly reduce cortisol levels.

Furthermore, adopting a healthy diet rich in antioxidants can help repair some of the cellular damage caused by stress. While it’s challenging to completely reverse the effects of stress on aging, these lifestyle changes can improve both physical and mental health and potentially slow the aging process.

Can Aging Be Slowed Down?

Aging can be slowed down through several scientifically supported methods. Key lifestyle choices such as maintaining a balanced diet rich in fruits, vegetables, and whole grains, regular physical activity, and avoiding harmful habits like smoking and excessive alcohol consumption can significantly delay the onset of aging process with its typical signs and diseases.

Caloric restriction has been shown in various studies to extend the lifespan of certain organisms by reducing metabolic stress. Advances in medicine, such as the use of antioxidants, hormone replacement therapies, and anti-aging skincare products, also contribute to slowing down the effects of aging.

Additionally, ongoing research into pharmacological agents that target aging processes, like senolytics which remove dysfunctional cells, holds promise for further slowing down the aging process in humans.

What is Promethease?

Promethease, now owned by MyHeritage, is a genetics literature retrieval system that builds a personal report based on your DNA data, primarily focused on health-related genetic variants.

The primary appeal of Promethease lies in its affordability and comprehensive reports, backed by SNPedia, a wiki database housing a vast amount of research findings related to single nucleotide polymorphisms (SNPs).

What is SNPedia?

SNPedia is an online database that contains information about single nucleotide polymorphisms (SNPs), which are variations at a single position in DNA among individuals. It serves as a wiki, allowing users to contribute and edit content under the oversight of its founders. SNPedia links genetic data to medical and physiological information to help individuals understand how genetic variations may influence their health and traits.

The website utilizes data primarily from scientific studies and public databases, providing details on how specific SNPs might be associated with health conditions, traits, or responses to drugs. It’s a valuable resource for both researchers and individuals interested in personal genomics and precision medicine.

Uploading DNA Data

Getting started with Promethease is relatively straightforward. Once you access their website, they provide a list of terms and conditions you should accept before proceeding with the tool.

You can directly import your DNA raw data file from another company or upload it manually after paying a fee of USD 12.

Promethease accepts raw data from several providers, including 23andMe, AncestryDNA, and MyHeritage DNA.

Terms in the Report Explained

Here are some terms you might encounter in a Promethease report:

SNP (Single Nucleotide Polymorphism): An SNP represents a difference in a single DNA building block called a nucleotide. SNPs occur normally throughout a person’s DNA and are the most common genetic variation among people. They can act as biological markers, helping scientists locate genes associated with any disease.
Genotype: Your genotype is the specific allelic composition at a particular SNP. It represents the precise variants of a gene you have inherited. For example, at given positions in the DNA, you might have a genotype of AA, AG, or GG.
Magnitude: This is a measure of how significant or impactful a finding is within the report. It is a subjective score assigned by SNPedia contributors ranging from 0 (least significant) to 10 (most significant). Higher magnitudes typically indicate findings of greater potential interest or importance.
Repute: This term refers to whether a SNP is considered “Good” or “Bad.” It indicates the overall effect of the SNP according to scientific studies, whether it is a protective effect or a risk factor for a condition.
Frequency: This term refers to how common a particular allele of a SNP is in the general or specific populations. It helps to understand how rare or common a genetic variation is among different groups.
RSID (Reference SNP cluster ID): This is an identifier used by researchers and databases to denote a specific SNP. It helps to track and reference specific genetic variations consistently across different studies and reports.
Phenotype: The term phenotype refers to observable characteristics or traits of an individual that result from the interaction of their genotype with the environment. It can include physical traits like height, eye color, and disease susceptibility.
Odds Ratio: This measure is used in statistical analysis to describe the strength of association or non-independence between two data values. In the context of genetics, it represents how much a particular SNP increases or decreases the risk of a disease.
Risk Allele: This is the specific gene variant version associated with an increased risk of a particular trait or disease.
Protective Allele: It is a version of a gene variant that can reduce the risk of a particular trait or disease.

These terms are used within Promethease reports to provide detailed insights into your genetic make-up, and how it might influence various health-related traits and conditions. Understanding these terms can help you better interpret the results of your genetic analysis.

Turn-Around-Time

It may take up to 24 hours for Promethease to generate the report, depending on the server load.

Upon receiving the email that the report is ready, you can navigate the website and immerse yourself in a wealth of information. The report has numerous sections on various conditions, traits, and medications.

Each genetic variant in the report is presented with a magnitude score, indicating the importance of that particular SNP variant.

Furthermore, it indicates whether the variant is good or bad and its frequency within the population.

The Promethease Report

One of the first impressions of the Promethease report is its sheer volume of data. It can feel overwhelming if you are new to genetics.

Promethease report is text-based with limited visuals, which can be challenging to read for the uninitiated.

The report also uses scientific language and jargon like SNP, allele, genotype, or rsID. If unfamiliar with these terms, you might frequently need to refer to external resources to understand the report fully.

Accuracy and Interpretation

Promethease pulls data from SNPedia. However, it is crucial to remember that interpreting genetic data, especially in the context of health, is complex.

The presence of a particular SNP allele might increase the risk of a condition, but it doesn’t guarantee you’ll get it. Many factors, including other genes and environment, come into play.

Promethease emphasizes that its report is not a diagnosis and that customers should discuss concerning findings with a healthcare professional.

Can Family Tree DNA (FTDNA) data be Uploaded to Promethease?

Family Tree DNA (FTDNA) allows users to download their raw DNA data, which they can upload to a third-party tool like Promethease for additional analysis.

This raw data includes results from FTDNA’s Family Finder (autosomal DNA), Y-DNA, and mtDNA tests.

However, it’s important to note that Promethease is designed to interpret autosomal data related to health and traits.

While you can technically upload Y-DNA and mtDNA data to the site, the interpretations for these data are limited, as they are not the primary focus of the Promethease database.

It is also essential to check the terms and conditions and privacy policies of any third-party tools you consider using, as using such services can often have implications for your genetic data privacy.

Understanding The APOE Gene Part I: The Basics

Date of Content: March 19, 2024

Disclaimer: This article is meant for informational purposes only. LifeDNA does not offer clinical analyses nor diagnoses for any conditions discussed herein or otherwise.

A few genes and their variants stand out for their profound impact on our health in the intricate web of human genetics. The APOE (apolipoprotein E) gene is one such gene, commanding attention for its significant role in lipid metabolism and its association with various conditions.

The APOE gene is located on chromosome 19. It is best known for its involvement in the body’s ability to process fats and for influencing conditions ranging from cardiovascular disease, affecting the functioning of the heart, to Alzheimer’s disease. The importance of the APOE gene in medical research and personalized healthcare continues to grow as we uncover more about its diverse roles in the body.

This article delves into the APOE gene, exploring its biological functions, genetic variations, and the implications of these variations on health and disease. By understanding the APOE gene, we can better grasp the complexities of genetic influence on health and pave the way for more personalized medical interventions.

The Biology of APOE

The APOE gene provides instructions for making a protein called apolipoprotein E. This protein is crucial for the normal catabolism (breakdown) of triglyceride-rich lipoprotein constituents.

In simpler terms, it plays a vital role in metabolizing and transporting fats and cholesterol throughout the body, aiding in the clearance of these substances from the bloodstream.

Apolipoprotein E is a prominent component of very low-density lipoproteins (VLDL), which are precursors to the more well-known low-density lipoprotein (LDL), often referred to as “bad cholesterol.”

Beyond its role in lipid metabolism, APOE plays vital roles in several other biological processes, including immune regulation and neural repair. Its presence in different tissues and organs, notably the liver and brain, underscores its multifaceted role in maintaining health and its potential implications in disease processes.

Genetic Variations of APOE and Their Significance

The APOE gene exists in three principal allele forms: ε2, ε3, and ε4, creating a genetic variant that influences the protein’s structure and function. These alleles determine the individual’s APOE genotype, which can be combinations of the three alleles (e.g., ε3/ε3, ε3/ε4, ε4/ε4).

ε2 allele is the least common. It is associated with a decreased risk of Alzheimer’s but an increased risk of type III hyperlipoproteinemia (a condition that can lead to cardiovascular disease).
ε3 allele is the most common, considered the “neutral” allele, with no increased risk of Alzheimer’s or heart disease.
ε4 allele is associated with an increased risk of Alzheimer’s disease and cardiovascular diseases. Carrying even one ε4 allele increases the risk, and having two ε4 alleles further elevates this risk.

The distribution of these alleles varies widely across different populations and ethnic groups, affecting the prevalence of related diseases. Understanding one’s APOE genotype can offer insights into the potential health risks and the preventive measures that may be most effective.We will cover the population-specific influence of APOE in Part II.

APOE and Its Link to Diseases

The APOE gene’s association with various diseases, most notably Alzheimer’s disease and cardiovascular disease, underscores its importance in human health and disease. The link between APOE alleles and these conditions offers a window into the genetic underpinnings of disease risk and progression.

Alzheimer’s Disease (AD)

The ε4 allele of the APOE gene is the strongest-known genetic risk factor for late-onset Alzheimer’s disease, expressed in more than half of the affected patients. Individuals carrying one ε4 allele have an increased risk of developing the disease, and the risk is even higher for those with two ε4 alleles. The presence of the ε4 allele is associated with earlier onset of AD symptoms and a more rapid progression of the disease.

In a study examining 179 senile dementia of the Alzheimer type (SDAT) patients, 154 controls, and 167 subjects with age-related memory complaints (ARMC), it was found that the APOE-ε4 allele frequency was notably higher in SDAT patients (27%) compared to controls (10%) and stable ARMC subjects (15%). Furthermore, among ARMC subjects, those who carried the ε4 allele had a three-fold increased risk of developing dementia compared to non-carriers. Additionally, older age at the onset of memory decline and lower initial scores were also associated with an increased risk of dementia in ARMC subjects.

Two years ago popular Marvel star Chris Hemsworth discovered that he had two copies of the APOE4 gene, inherited from both his mother and father. You can read about his journey of discovery here.

Conversely, the ε2 allele may offer some protection against AD, although its protective mechanism is not fully understood.

A 2020 study revealed significant protective effects of ε2 against AD-related pathologies such as amyloid plaques and Braak stage compared to e3/e3 carriers and e4 carriers. The study also noted that, unfortunately, in ε2/ε4 carriers, the risk for AD pathologies resembles that of ε4 carriers rather than ε2 carriers.

Cardiovascular Disease (CVD)

An early study suggested that the presence of ε2 or ε4 alleles in men is associated with a heightened risk of CVD, emphasizing the potential utility of genotype information in identifying individuals prone to CVD events.

In addition to the increased risk for AD, the APOE ε4 allele is also associated with an increased risk of cardiovascular disease. This risk is partly due to the allele’s effect on lipid metabolism, leading to higher LDL cholesterol levels and potentially a significant buildup of plaques in the arteries.

The ε2 allele, despite its protective role against Alzheimer’s, can predispose individuals to type III hyperlipoproteinemia, a condition that elevates triglyceride levels and may increase the risk of heart disease.

Beyond these well-established links, research has suggested potential associations between APOE alleles and other conditions, including diabetes, inflammatory diseases, and age-related macular degeneration, highlighting the gene’s broad impact on health.

Implications for Personalized Medicine

Understanding an individual’s APOE genotype has significant implications for personalized medicine, offering insights that can guide preventive health strategies, lifestyle adjustments, and potentially tailored medical treatments.

Preventive Health Strategies: Knowledge of one’s APOE status can inform personalized approaches to disease prevention. For instance, individuals with the ε4 allele might benefit from early interventions to manage cholesterol levels and reduce Alzheimer’s risk, such as regular physical activity, a heart-healthy diet, and cognitive training exercises.
Lifestyle Adjustments: Awareness of APOE-related risks can motivate lifestyle changes to mitigate these risks. It could include dietary modifications, increased emphasis on cardiovascular exercise, and monitoring heart health and cognitive function regularly.
Tailored Medical Treatments: In the future, the APOE genotype could inform the development and application of targeted therapies, especially for conditions like Alzheimer’s, where we can customize preventive and therapeutic strategies based on genetic risk factors.

Future Directions in APOE Research

Ongoing research into the APOE gene continues to uncover its complex roles in health and disease. Future studies aim to elucidate mechanisms by which APOE alleles influence disease risk and progression to develop more effective treatments. Research also explores the gene’s potential roles in other conditions, expanding our understanding of its impact on human health.

Takeaway

The APOE gene’s significance extends far beyond its role in lipid metabolism, with its variants influencing the risk and progression of Alzheimer’s disease, cardiovascular disease, and potentially other conditions. Understanding the genetic variations of APOE and their associations with diseases offers valuable insights for personalized medicine, highlighting the importance of genetics in health and disease management.

As research progresses, the potential for targeted interventions based on APOE status holds promise for improving outcomes for individuals with increased genetic risks. Embracing the advancements in genetic research can empower individuals and healthcare providers to make informed decisions, leading to better health and well-being.

Mitochondrial DNA Sequencing

Mitochondria possess a circular independent genome, spanning 16,569 base pairs and a non-coding control region that measures approximately 1,160 base pairs. Within each eukaryotic cell, there are between 100 to 10,000 copies of mitochondrial DNA (mtDNA), a significantly higher copy number than that of nuclear DNA. The abundance of mtDNA, even in limited or degraded samples, makes mtDNA analysis a viable option in instances where nuclear DNA analysis is not successful.

The circular structure of mtDNA contributes to its resilience against environmental and enzymatic degradation, making it more stable over time than nuclear DNA. This stability allows for the analysis of ancient samples.

Additionally, mtDNA is inherited maternally, enabling the determination of matrilineal ancestry. Next Generation Sequencing (NGS) techniques are employed for the analysis of mitochondrial DNA, offering options for either control region sequencing or whole genome sequencing. This method proves effective, especially in cases where analysis of nuclear DNA has been unsuccessful.

23andMe’s New ‘1473 Antibody Clinical Trial: What You Need To Know

Date of Content: March 22, 2024
Written by: Avanthika Nityanand
Reviewed by: Maarit Tiirikainen, PhD

23andMe announced today that the first participant has been administered a dose in a Phase 1 clinical trial.

This trial aims to evaluate 23ME-01473 (‘1473), a new investigational antibody for treating advanced solid tumors. The antibody targets ULBP6, a discovery made using the company’s proprietary research platform, which boasts the world’s largest contactable database of de-identified human genetic and phenotypic information.

It marks the third drug target identified by the company’s research platform to advance to clinical trials in less than four years.

This achievement is a good example of how, with your informed consent, your genetic data acquired via consumer tests (DTC) can be used for advancing medical research: Your genetic data can contribute to breakthroughs in understanding diseases, leading to the development of new treatments and preventive strategies. This can benefit society and potentially also aid in finding cures for rare genetic conditions.

Working with trustworthy companies such as 23andMe, your genetic data can be used for research while still recognizing the balance between contributing to scientific advancements and considering personal privacy concerns.

What Is a Phase I Clinical Trial?

A Phase 1 clinical trial is the first stage in the clinical trials process for testing new medical treatments in humans. These trials primarily focus on assessing the safety, tolerability, pharmacokinetics (how the drug gets absorbed, distributed, metabolized, and excreted in the body), and pharmacodynamics (the effects of the drug and its mechanism of action within the body) of a drug or therapeutic intervention. Phase 1 trials are crucial for determining the optimal dosage range and identifying potential side effects of the drug.

Typically, Phase 1 trials involve a small number of participants, often between 20 to 100 healthy volunteers or patients, depending on the drug’s intended use and its expected effects. The participants can be patients (having the condition the drug aims to treat) if researchers feel the drug might have significant effects. The main goal is not to test the drug’s efficacy in treating a condition but to gather initial data on its safety and how the body responds.

These trials are essential steps in developing new medications and treatments. They provide the foundation for further research in Phase 2 and Phase 3 trials, where they test for effectiveness and safety.

About the 23andMe Trial

According to their press release, the drug ‘1473 focuses on a critical aspect of cancer therapy: enhancing the body’s natural immune response to tumors. It does this by targeting ULBP6, a molecule found on the surface of cancer cells. ULBPs, including ULBP6, are ligands that can bind to a receptor called NKG2D present on Natural Killer (NK) cells and T cells, which are vital immune system components. When ULBPs bind to NKG2D, they alert the immune system to target and destroy the cancer cells.

However, cancer cells have developed a way to avoid this immune attack. It releases (or sheds) these ULBP molecules from its surface into the surrounding environment. Once shed, these ULBPs no longer signal the immune cells to attack because they are no longer attached to the cancer cells. Instead, they float around and bind to NKG2D receptors on NK and T cells in the bloodstream, acting as “decoys” that distract the immune cells and suppress their ability to target the actual cancer cells.

‘1473 aims to block these free-floating, or soluble, ULBP6 molecules from binding to the NKG2D receptor. By preventing this binding, ‘1473 helps to restore the immune system’s ability to recognize and kill cancer cells.

Moreover, they claim to have enhanced ‘1473 to activate Fc receptors on NK cells, providing an additional method for these immune cells to identify and destroy ULBP6-expressing cancer cells. This dual action—blocking the immunosuppressive effects of soluble ULBP6 and enhancing the NK cells’ ability to kill cancer cells—makes ‘1473 a promising therapeutic candidate.

23andMe immuno-oncology genetic signature uncovered the potential of ULBP6 as a cancer drug target. This innovative approach by 23andMe utilizes genetic data to find evidence of genetic variants that boost immune function and reduce cancer risk. By analyzing the genetics of the immune system, 23andMe can identify specific immune-related genes that play significant roles in cancer biology. It includes determining which genes contain variants that might change a person’s risk of developing cancer and offering a personalized approach to cancer therapy.

What Gaps in Cancer Research Does ‘1473 Aim to Address?

The 23andMe drug trial for ‘1473 addresses research gaps in cancer, notably in immunotherapy and personalized medicine. It focuses on enhancing the understanding and application of genetic information to improve cancer treatment outcomes.

Specifically:

Immunotherapy Outcomes: Exploring how to make immunotherapy more effective for a broader range of patients. By targeting specific mechanisms like the interaction between ULBP6 and the NKG2D receptor on immune cells, the research aims to improve the immune system’s ability to recognize and destroy cancer cells.
Personalized Medicine: Using genetic signatures to identify drug targets, such as ULBP6, is a step toward personalized or precision medicine. The trial leverages genetic information to tailor treatments based on individual genetic makeup, potentially increasing the efficacy of cancer therapies.
Understanding Resistance to Therapy: By focusing on the mechanisms that allow cancer cells to evade the immune system, such as the shedding of ULBP ligands, the trial contributes to understanding why some cancers become resistant to existing treatments and how new therapies can overcome this resistance.

Through its focus on these areas, the 23andMe drug trial demonstrates how genetic research can fill critical gaps in current cancer treatment strategies, particularly by enhancing the effectiveness of immunotherapy and advancing personalized medicine.

What Does this Trial Mean for You?

The initiation of the new 23andMe trial could potentially mark a significant advancement in personalized medicine and cancer treatment. For individuals diagnosed with advanced solid tumors, this trial might offer a glimpse into future treatment possibilities that are more aligned with their specific genetic profiles, potentially offering alternatives to conventional therapies. By targeting the genetically identified molecule ULBP6, the trial suggests an evolving landscape where treatments are increasingly tailored to the unique genetic makeup of each patient, hinting at a future where immunotherapy could become even more effective and personalized.

Although in its early stages, this Phase 1 trial is poised to contribute essential data on the safety, tolerability, and optimal dosing of ‘1473, laying the groundwork for further research. Moreover, its findings could enrich the field of genetic research, opening doors to further discoveries that might lead to innovative treatments.

Genetics And Wellness

Genetics significantly influences physical wellness, as it dictates susceptibility to conditions such as heart disease, diabetes, obesity, and certain cancers. We can trace back to genetic predispositions, the way our bodies metabolize food, respond to exercise, manage cholesterol levels, and regulate blood pressure. The foundational genetic blueprint is crucial in how individuals approach their diet and physical activity for optimal well-being.

Mental wellness is another aspect profoundly impacted by genetics. The risk for mental health disorders, including depression, anxiety, bipolar disorder, and schizophrenia, can be inherited. These conditions result from the complex interplay between multiple genes and environmental factors, affecting an individual’s mental well-being and resilience to psychological stress.

Longevity and the aging process are also under genetic influence. Some gene variants are linked to longer life expectancies and a lower incidence of age-related diseases, suggesting that genetics plays a part in determining how long and how well we live.

Nutritional needs vary from person to person, partly due to genetic differences. These variations can influence how the body processes and absorbs vitamins, minerals, and other nutrients. This can lead to specific dietary requirements, susceptibilities to deficiencies, or intolerances such as lactose intolerance or celiac disease.

Sleep patterns, such as preferences for being a morning or evening person (chronotype) and the risk for sleep disorders like insomnia or sleep apnea, also have a genetic basis. Various genetic factors contribute to the diversity in sleep habits and quality among individuals.

The risk of addiction and substance use disorders, including those related to alcohol and nicotine, is influenced by genetics. We can see this impact in the metabolization of substances and how the brain reward system responds, affecting an individual’s susceptibility to addiction.

Athletic performance is another area where genetics holds sway. Genetic factors can affect muscle composition, cardiovascular fitness, and how the body responds to physical training, influencing an individual’s natural athletic abilities and how quickly they recover from exercise.

Stress response varies widely among individuals, with genetics playing a vital role in determining physiological reactions to stress and the ability to cope with psychological stressors. Genetic variation affects how individuals manage stress and maintain mental health.

Finally, reproductive health, including aspects such as fertility, risk of miscarriage, and the timing of menopause, is influenced by genetics. This highlights the role of genetics in individual health and wellness and the broader context of family planning and reproductive choices.

Smoking Behavior & Nicotine Dependence

Smoking behavior refers to the act of inhaling and exhaling the smoke from cigarettes or other tobacco products. Nicotine dependence is a condition marked by an addiction to nicotine, a chemical in tobacco, causing individuals to continue smoking despite the known health risks.

The CYP2A6 gene plays a crucial role in the metabolism of nicotine. Genetic variations, such as the rs4105144 polymorphism in the CYP2A6 gene, can lead to differences in how individuals process nicotine. The rate of nicotine metabolism can influence the likelihood of developing nicotine dependence, the number of cigarettes smoked per day, and also how easy or difficult it is to quit smoking.

Understand how genetics impacts smoking behavior in more detail.

Alcohol Consumption

Alcohol consumption involves drinking beverages containing alcohol (ethanol). It ranges from occasional drinking to heavy and binge drinking, with varied effects on health and behavior.

We can attribute individual differences in alcohol metabolism rates to genetic variations in the enzymes responsible for alcohol breakdown, specifically the alcohol dehydrogenases. Individuals with certain genetic predispositions may break down alcohol more slowly, leading to prolonged exposure to alcohol in the body. This extended exposure can elevate the risk of developing Alcohol Use Disorder (AUD).

Understand in-depth the genetics of alcohol metabolism.

Insomnia

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or experiencing restful sleep, leading to daytime fatigue and other symptoms.

The serotonin transporter gene polymorphism, 5-HTTLPR, is frequently studied in psychiatric genetics, including its relationship with insomnia. 5-HTTLPR represents genetic variants in the serotonin transporter gene, SLC6A4, also known as SERT. SLC6A4 is responsible for the reuptake of serotonin, a neurotransmitter playing a significant role in mood regulation, among other functions. The 5-HTTLPR variants affect how efficiently serotonin recycles back into nerve cells after release. They can influence an individual’s susceptibility to mood disorders like depression and anxiety.

Insomnia has several other genetic associations. Read about it in our article- Is Insomnia Genetic?

Appendicitis

Appendicitis is the inflammation of the appendix, a small pouch attached to the large intestine, causing severe abdominal pain and requiring prompt medical treatment, often surgery.

Resting Heart Rate

The resting heart rate represents the number of heartbeats per minute while at rest. It is an important indicator of cardiovascular health, with lower rates generally indicating better cardiovascular fitness.

In a 2010 GWAS, researchers found a significant association with the SNP rs9398652 of the GJA1 gene. This variant is linked to a 12.6 ms shorter RR interval per the minor A allele, equating to a heart rate increase of 0.95 beats per minute. Another SNP, rs11154022, located just 8 kb from GJA1, also showed a significant genome-wide association but in the opposite direction, extending the RR interval and lowering heart rate. These SNPs have a low correlation with each other, suggesting independent genetic influences on heart rate.

Read the complete analysis of the genetics of resting heart rate in our article.

Inguinal Hernia

An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles near the groin area, often causing pain and swelling.

Variations in the EFEMP1 gene, especially the SNP rs2009262, can affect the structure and function of extracellular matrix proteins. Such alterations in the extracellular matrix can weaken connective tissues, potentially aggravating conditions like hernias by reducing tissues trength and integrity.

Motion Sickness

Motion sickness happens when the brain receives conflicting signals from the eyes, inner ears, and other body parts during movement, leading to dizziness, nausea, and vomiting.

Researchers found notable genetic associations with motion sickness in a GWAS involving over 80,000 participants. One such association was rs66800491, located near PVRL3, a gene implicated in eye development. Another genetic marker was SNP rs2153535 near MUTED, which plays a role in balance regulation. Many of the discovered SNPs are near genes involved in neurological functions, such as NLGN1 and CBLN4.

Inflammatory Response

The inflammatory response is the body’s defense mechanism against infection and injury, involving increased blood flow, white blood cell activation, and release of chemicals to fight off pathogens and to repair tissue.

Genetic markers associated with the inflammatory response encompass various genes responsible for coding proteins that regulate different facets of the immune system. The presence of variations in genes that encode both pro-inflammatory and anti-inflammatory cytokines is crucial. Polymorphisms in the genes responsible for producing tumor necrosis factor-alpha (TNF-α), interleukin-1 (IL-1), and interleukin-6 (IL-6), for instance, are connected to changes in cytokine levels and a heightened risk of developing inflammatory conditions.

Potential For Cannabis Dependence

Potential for cannabis dependence refers to the likelihood of developing a reliance on cannabis. It can affect your ability to stop or control cannabis use despite negative consequences.

Multiple genes are recognized as likely factors in the development of cannabis dependence. Specifically, genetic differences within the endocannabinoid system, notably in the cannabinoid receptor 1 (CNR1) gene, are thought to elevate the risk of developing a dependency on cannabis. Such genetic variations may alter the operation of the endocannabinoid system, thereby affecting a person’s reaction to cannabis.

Diet & DNA Damage

DNA damage refers to changes to the DNA structure that can lead to mutations and disease. A major cause of DNA damage is oxidative stress, which occurs when there’s an imbalance between free radicals and antioxidants in the body. Diets high in processed foods, sugar, and unhealthy fats can increase oxidative stress.

Several genetic variants have been found to influence DNA damage from diet. Of these, the CYP1A2 SNP rs762551 has been extensively researched. Individuals carrying the A-allele face a higher risk of developing colorectal cancer (CRC) when their diet includes red meat. Similarly, possessing the A-allele in the AHR SNP rs2066853 has also been linked to an elevated risk of CRC.

Menstrual Cycle Length

Menstrual cycle length is measured from the first day of one menstrual period to the first day of the next, typically ranging from 21 to 35 days in adults.

Research indicates that various genetic factors are involved in determining the characteristics of a woman’s menstrual cycle, including its length, regularity, and the onset of menopause. For instance, variations in genes related to the estrogen receptor, gonadotropin-releasing hormone, and those involved in the hypothalamic-pituitary-gonadal axis can affect how the body regulates the menstrual cycle.

Excessive Sweating

Excessive sweating, or hyperhidrosis, involves abnormal, profuse sweating unrelated to heat or exercise and can negatively affect social, professional, and daily activities.

Research has identified genetic markers associated with excessive sweating, highlighting specific variations on chromosomes 2 and 16. The most notable findings were in the chromosome 16 region, where several SNPs, including the well-documented ABCC11 missense variant (rs178229310), were linked to this condition. The ABCC11 protein plays a crucial role in transporting small molecules across the apical membranes of apocrine secretory cells. These genetic insights are instrumental for dermatologists exploring the genetic foundations of skin traits, including hyperhidrosis (excessive sweating).

Male Pattern Baldness

Male pattern baldness is a genetic condition resulting in hair loss in a well-defined pattern. It begins with a receding hairline and thinning on the crown, gradually leading to partial or complete baldness.

A primary factor in assessing the risk of male pattern baldness is family background, especially close maternal relatives, such as the maternal grandfather, who have had this condition. This suggests a higher likelihood of inheriting the genetic tendency towards male pattern baldness. The Androgen Receptor (AR) Gene, found on the X chromosome, plays a crucial role in this type of hair loss. Changes in the AR gene can increase the sensitivity of hair follicles to dihydrotestosterone (DHT), a hormone that causes follicles to shrink and produce thinner, shorter hair strands.

Read our full analysis: Genetics of Male Pattern Baldness

Longevity

Longevity refers to the length of an individual’s life and encompasses the pursuit of extending life expectancy while maintaining the quality of life. It can be influenced by genetic, environmental, and lifestyle factors.

Longevity is a complex trait influenced by both genetic and environmental factors. Significant strides have been made in identifying specific genetic markers contributing to an individual’s lifespan. The APOE gene, responsible for transporting fats, plays a key role in this context. Variants such as APOE2 and APOE3 are associated with longer lifespans and decreased risk of Alzheimer’s disease. Conversely, the APOE4 variant is often linked with a reduced lifespan and heightened risk of developing Alzheimer’s.
