No. One may have the genetic markers that predispose them to a condition, but still not develop it because their environmental factors may offset such risks.
On the other hand, even if you have a low likelihood for a particular condition, it does not mean that you will never develop it.
For example, if your report shows that you have a low sensitivity to gluten, that does not necessarily mean that you will never be able to develop the condition.
Gluten sensitivity can be triggered by several factors such as surgery, pregnancy, childbirth, viral infections, and severe emotional stress.
In addition, there are multiple genes that influence your results.
It is also essential to understand that most traits are polygenic in nature, meaning multiple genes are responsible for their expression in our bodies.
So, impairment in one gene cannot contribute alone to your actual experience. Some mechanisms may still try to offset or compensate for any errors in our bodies.
