Genetic factors predicting risk of mood disorders in adolescents

Adolescent-onset mood disorders are associated with increased genetic risk relative to later-onset. Although not currently clinically applicable, genetic factors, with a focus on PRS and FGRS, can help to predict onset and course of mood disorders in adolescents. The use of PRS and FGRS, combined with environmental factors, improves prediction models for mood disorders in adolescents. Additionally, it also provides information on the etiology of these disorders, for example by examining parent-offspring and peer group associations in genetically informative study designs.
