This article is about how genetics could play a role in mental illness but not in the way you might think. Trying to figure out the genetic and cognitive causes of mental illness' in detail has always been a problem without a solution. It turns out, through comparing different individuals with a common "mental illness gene", They have seen a variety of outcomes depending on their environment. Their final conclusion was that there is no gene that directly correlates to mental illness, in a yes or no manner. On the other hand, there are genes that can affect how susceptible someone is to the stressors in an environment. I believe that this is a good starting point but when handling something as mental illness, that has had several definitions over time, there needs to be a lot of data to make a solid point in either direction.
