This study used polygenic scoring (PGS) to test whether puberty-related genes were correlated with depressive symptoms, and whether there were indirect effects through pubertal maturation. The sample included 8,795 adolescents from the Avon Longitudinal Study of Parents and Children (measures of puberty drawn ages 8-17 years; of depressive symptoms at age 16.5 years). The PGS (derived from a genome-wide meta-analysis of later age at menarche) predicted boys' and girls' later pubertal timing, boys' slower gonadal development, and girls' faster breast development. Earlier perceived breast development timing predicted more depressive symptoms in girls. Findings support shared genetic underpinnings for boys' and girls' puberty, contributing to multiple pubertal phenotypes with differences in how these genetic variants affect boys' and girls' development.
