In the VS, but not in the dorsal striatum, we observed enrichment of DE genes in the GWAS signal of PAU (p = 0.045). In the putamen DE genes were enriched for GWAS signal from a study comparing individuals with OUD to unexposed controls (p = 0.025). None of the DE genes in any of the brain regions showed enrichment for signals from a GWAS of Cannabis Use Disorder or AUD.
