Genetic susceptibility in Dupuytren's disease: Lack of association of a novel transforming growth factor β₂ polymorphism in Dupuytren's disease

The genes involved in the pathogenesis of Dupuytren's disease have yet to be identified. In this study, we tested for an association between Dupuytren's disease (DD) and a novel insertion polymorphism within the 5′-untranslated region (5′-UTR), of the TGFβ₂ gene. DNA samples from 179 DD patients and 187 ethnically matched controls were examined. There was no statistically significant difference in TGFβ₂ allele frequency distributions between cases and controls for the TGFβ₂ polymorphism.
