Abstract We determined the genotypes of the alcohol dehydrogenase (ALDH) and aldehyde dehydrogenase (ALDH2) loci of different ethnic groups living in Brazil, using saliva DNA amplified by PCR and allele-specific oligonucleotides. Self-reports of flushing reaction after drinking were also studied. the allelic frequencies of ADH2 and ALDH2 were found to be lower than those reported other authors, which might be a result of the admixture origin of the Brazilian population. Variability in facial flushing reaction suggests that other factors play a role in the expression of alcohol-induced flushing. (C) 1997 Elsevier Science Inc.
