OBJECTIVE: The aim of the study was to analyse the frequencies of rs1229984 genotypes within the alcohol dehydrogenase (ADH1B) gene in a Gypsies/Roma population and compare them with other populations and with ethanol consumption. METHODS: We analysed the ADH1B (rs1229984; Arg47→His; c.143G>A) genotype using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) in two ethnically different groups - Gypsies/Roma (N = 301) and Czechs (N = 300) where one day alcohol consumption was recorded. RESULTS: ADH1B genotype/allelic frequencies did not significantly differ between the populations (p = 0.32). The frequency of minor A allele carriers was slightly higher in Gypsies/Roma (14.7%) than in Czechs (11.9%). The prevalence of subjects reporting alcohol intake on the previous day was non-significantly lower in Gypsies/Roma (10.5% vs. 16.4%), as was the amount of alcohol consumed the day before the examination in ethanol consumers (36.1 ± 18.3 g vs. 43.0 ± 27.2 g). CONCLUSIONS: The frequency of rs1229984 genotypes in the ADH1B gene within the Gypsies/Roma population corresponds with frequencies obtained in North India/Central Asia, the putative country of this ethnic origin. Our results suggest that the minority Gypsies/Roma population consume slightly less alcohol than the Czech majority population.
