Overview

Observational analysis reveals polygenic scores for depression impact offspring psychopathology, highlighting genetic factors.

Key Points

  • Increased polygenic scores for depression mediate the effects of family history on offspring psychopathology.
  • Greater PGS for depression and bipolar disorder were significantly associated with family history, estimating a combined impact of 1.39–5.87%.
  • Observational analysis utilized data from 11,875 children in the Adolescent Brain Cognitive Development study across multiple ancestries.
  • Findings support the genetic link in the intergenerational transmission of depression, indicating new avenues for early identification.
