Study reveals genes associated with heavy drinking and alcoholism


A large genomic study of nearly 275,000 people has revealed new insights into genetic drivers of heavy drinking and alcohol use disorder (AUD), the uncontrollable pattern of alcohol use commonly referred to as alcoholism. In the largest-ever genome-wide association study (GWAS) of both traits in the same population, a team of researchers found 18 genetic variants of significance associated with either heavy alcohol consumption, AUD, or both.
