Multivariate genome-wide association meta-analysis of over 1 million subjects identifies loci underlying multiple substance use disorders 

Nature Mental Health

Recent large-scale genome-wide association studies (GWASs) show that the genetic architecture of substance use disorders (SUDs) is characterized by a high degree of commonality, i.e., a general addiction genetic factor likely conveys vulnerability to multiple SUDs. Genetic liability to substance use disorders can be parsed into loci that confer general or substance-specific addiction risk. This is a multivariate genome-wide association meta-analysis that disaggregates general and substance-specific loci from published summary statistics of SUDs. Findings provide insight into genetic risk loci for substance use disorders that could be leveraged as treatment targets.
