Abstract

Background: We conducted a genomewide association study (GWAS) for maximum number of alcoholic drinks consumed in a 24-hour period ("MaxDrinks"), in 2 independent samples comprised of over 9,500 subjects, following up on our GWAS for alcohol dependence (AD) in European Americans (EAs) and African Americans (AAs). Methods: The samples included our GWAS samples (Yale-UPenn) recruited for studies of the genetics of drug or AD, and a publicly available sample: the Study of Addiction: Genetics and Environment (SAGE). Genomewide association analysis was performed for ~890,000 single nucleotide polymorphisms (SNPs) using linear association random effects models. EAs and AAs were separately analyzed. Results: The results confirmed significant associations of the well-known functional loci at ADH1B with MaxDrinks in EAs (rs1229984 Arg48His p=5.96×10<sup>-15</sup>) and AAs (rs2066702 Arg370Cys, p=2.50×10<sup>-10</sup>). The region of significant association on chromosome 4 was extended to LOC100507053 in AAs but not EAs. We also identified potentially novel significant common SNPs for MaxDrinks in EAs in the Yale-UPenn sample: rs1799876 at SERPINC1 on chromosome 1 (4.00×10<sup>-8</sup>) and rs2309169 close to ANKRD36 on chromosome 2 (p=5.58×10<sup>-9</sup>). After adjusting for the peak SNP rs1229984 on ADH1B, rs1799876 was nearly significant (p=1.99×10<sup>-7</sup>) and rs2309169 remained highly significant (2.12×10<sup>-9</sup>). Conclusions: The results provide further support that ADH1B modulates alcohol consumption. Future replications of potential novel loci are warranted. This is the largest MaxDrinks GWAS to date, the first in AAs.
