Polygenic Risk Score Prediction of Alcohol Dependence Symptoms Across Population‐Based and Clinically Ascertained Samples

Abstract excerpt

BACKGROUND: Despite consistent evidence of the heritability of alcohol use disorders (AUDs), few specific genes with an etiological role have been identified. It is likely that AUDs are highly polygenic; however, the etiological pathways and genetic variants involved may differ between populations. The aim of this study was thus to evaluate whether aggregate genetic risk for AUDs differed between clinically...
