Does having a high risk mean that I will develop the disease or have a complex personal trait?
No, since diseases and complex traits are regulated by both genetic and environmental factors.
Genetic risk measures the impact of the genetic factor on the development of a disease. However, environmental factors ultimately have a strong impact on the development of the disease or trait.
A clear example is the relationship between lung cancer and tobacco use. In this case, a person with a high genetic predisposition to lung cancer, but with a healthy lifestyle, may not develop the disease. On the other hand, a person with a low genetic predisposition, but who is a smoker and has unhealthy habits, may develop it.
