- Abstract
Alcohol use disorder (AUD) is influenced by genetics, especially in the metabolism of ethanol. The ethanol dehydrogenase genes (ADH1B/ADH1C), which convert ethanol, have single nucleotide polymorphisms (SNPs) that result in isoenzymes with different catalytic rates. Studies have shown that the Arg48His, Arg370Cys, Arg272Gln, and Ile350Val SNPs contribute to AUD. This article reviewed the studies that investigated SNPs in ADH1B (Arg48His/Arg370Cys) and ADH1C (Arg272Gln/Ile350Val) and evaluated variations in the allele frequencies of these genes and their influence on AUD in different populations worldwide. The allele frequencies of the polymorphisms were compared by Pearson's chi-square and Fisher's exact tests (p < 0.05). The Arg48His SNP provides protection against AUD in Euro-Americans, Latin Americans, Europeans, Brazilians, Asians, and Australians. The Arg370Cys SNP provides protection against AUD in Afro-descendants. The Arg272Gln and Ile350Val SNPs predispose to AUD mainly in Europeans. The Arg48His, Arg370Cys, and Arg272Gln/Ile350Val SNPs were more frequent in East Asians (69.7%), Africans (19.1%), and Europeans (40.5%), respectively (p < 0.01). The different alleles of the ADH1B/ADH1C genes due to SNPs make an important contribution to AUD. The frequencies of these alleles vary among different populations, resulting in different effects on AUD.
