BAX and BCL2 Gene Polymorphisms in Rhegmatogenous Retinal Detachment.

PURPOSE: The purpose of this study was to investigate the potential association between rhegmatogenous retinal detachment (RRD) and BAX and BCL2 polymorphisms.

METHODS: This is a case control study of 99 patients with RRD and 120 healthy control subjects of Greek origin, surveyed for BAX and BCL2 polymorphisms (rs2279115 and rs4645878) and a potential correlation to RRD.

RESULTS: The rs4645878 AA genotype was found to be significantly associated with RRD (p = 0.003; OR: 6.89, 95% CI: 1.76-26.93), while the rs2279115 CC genotype as well as the C allele was not found in patients with RRD.

CONCLUSIONS: This is the first study evaluating the potential relationship between BCL2 and BAX gene polymorphisms and RRD in a Greek population, showing a significant association between BAX rs4645878 polymorphism and RRD susceptibility. This finding suggests that an apoptotic mechanism is implicated in the pathogenesis of RRD.
