Bladder cancer (BC) is a multifactorial disease with a poorly understood main cause. In this study, we aimed to evaluate the effect of the polymorphisms rs2228611 of the DNMT1 gene and rs1569686 of the DNMT3B gene on the susceptibility to develop Bladder Cancer in the Algerian population. A case-control study design was adopted, with DNA samples of 114 BC patients and 123 healthy controls. We found that the rs2228611 of the DNMT1 gene was strongly associated with an increased risk of BC development under genetic models: Codominant AG vs. GG (OR=2.54, 95% CI=1.21-5.51, adj p=0.015) and dominant AA+AG vs. GG (OR=2.24, 95% CI=1.12-4.60, adj p=0.023). However, no statistically significant association was observed between the rs1569686 of the DNMT3B gene and the predisposition to BC. To the best of our knowledge, this is the first peer-reviewed study to evaluate the effect of the rs2228611 polymorphism on bladder cancer occurrence. Our results suggest that the rs2228611 might be a potential biomarker for BC development risk. Additional studies are needed to validate our findings.
