title: Common variants of the ALDH2 and DHDH genes and the risk of Dupuytren's disease.
abstract: The object of this study was the investigation of four common variants of single nucleotide polymorphisms of the aldehyde dehydrogenase H2 gene and dihydrodiol dehydrogenase gene and their association with the occurrence of Dupuytren's disease. DNA samples were obtained from the peripheral blood of 300 consecutive patients. The control group comprised 300 healthy adults who were age matched with the Dupuytren's patients. All four common variants were analysed using TaqMan® genotyping assays and sequencing. The differences in the frequencies of variants of single nucleotide polymorphisms in patients and the control group were statistically tested. No significant differences were found in the frequencies of the variants of the aldehyde dehydrogenase H2 and dihydrodiol dehydrogenase genes between the groups. Likewise, no significant differences were found in the frequencies of the variants of the genes between men and women. We noted a statistically significantly higher prevalence of the variants of the dihydrodiol dehydrogenase gene (rs2270941 and rs11666105) in the group with a positive familial history of Dupuytren's disease, in comparison with the group with a negative familial history.
