ALCOHOL DEHYDROGENASE POLYMORPHISMS IN NATIVE AMERICANS: IDENTIFICATION OF THE ADH2*3 ALLELE
1997
Alcohol dehydrogenase (ADH) polymorphisms were evaluated among 95 Native American Mission Indians. Approximately equal frequencies of ADH 3*1 and ADH 3*2 alleles were found. Twelve individuals were heterozygous for ADH 2*3, an allele previously identified only in persons of African origin. None of the individuals with ADH 2*3 alleles was of purely Native American descent, although none had known African ancestry. These results suggest that these candidate genes deserve broader study among Native Americans and may provide increased understanding of the likely polygenic contributions to alcohol-related disorders in this population.
