Prospects of studying the polymorphisms of key genes of neurotransmitter systems: II. The serotonergic system

The review deals with the genetic principles of personality features that are helpful in both efficient athlete selection and improved training. The variations of the genes of the serotonergic system, associated with aggression, predisposition to depression, and antisocial behavior, receive special attention. It is important to assess the contribution of different combinations of serotonergic system genes into professional success of athletes.
