Association studies between the A1 allele of the dopamine D2 receptor (DRD2) gene TaqI A polymorphism and alcoholism remain controversial. A recent study from Japan demonstrated that the A1 allele is associated with severe alcoholism in the Japanese population. We were interested in knowing if this association also exists in the Atayals of Taiwan, who were found to have a higher prevalence of alcohol-use disorders than the Han Chinese in Taiwan. Genotype and allele frequencies were determined in alcohol-abusing, alcohol-dependent, and nonalcoholic control Atayal natives in Taiwan. A1 allele frequencies in alcohol-dependent, alcohol-abusing, and normal control Atayals were 0.39, 0.42, and 0.39, respectively. No difference in A1 allele frequency was found among these three groups. Our data do not support the hypothesis that the A1 allele of the TaqI A polymorphism of the DRD2 gene increases susceptibility to alcohol-use disorders in the Atayals of Taiwan. 18 refs., 1 tab.
