With longitudinal EHR data from the Million Veteran Program (MVP) linked to genetic data, we used two population-specific polymorphisms in ADH1B that are associated strongly with AUD in African Americans (AAs) and European Americans (EAs): rs2066702 (Arg369Cys, AAs) and rs1229984 (rs1229984" genes_norm="125">Arg48His, EAs) as criterion measures.

However, the suppressive effects of inactive ALDH2 and highly active ADH1B for AUDs are only partial and interact with other factors, such as personality traits, psychiatric comorbidities, and environmental factors.

Therefore, among those at risk for greater consumption, e.g. those who experienced childhood adversity, ADH1B-rs1229984 appears to have a stronger effect on alcohol consumption and consequently on risk for AUD symptom severity.

Our previous case-control study in a Tibetan population noted that the positive association between c2 allele of cytochrome P4502E1 (CYP2E1) gene and AUD might only exist in males who are homozygotes for 1 alleles of aldehyde dehydrogenase-2 (ALDH2) and alcohol dehydrogenase-1B (ADH1B) genes, but this interaction did not reach statistical significance.

These findings suggest that studies searching for genes relating to the LR to alcohol as a vulnerability factor for AUDs should consider controlling for ADH1B genotype, as the ADH1B*2 allele could obscure the impact of other genetic polymorphisms.

However, multivariate analyses under a hierarchically well-formulated model strategy with interaction and confounding assessment indicated that (i) heavy alcohol intake was a significant risk factor (odds ratio per 1.0 g of daily ethanol intake; 1.096, 95% confidence interval; 1.026-1.171) for developing AUD after adjusting for other confounders; and (ii) ADH2*1/1 genotype and ALDH2*1/1 genotype were not risk factors after adjusting for daily ethanol intake and other confounders.
