ERCC1 and urinary bladder carcinoma: Matullo et al. reported that the ERCC1-19007C variant allele (CC+CT versus TT: odds ratio (OR), 0.62; 95% confidence interval (CI), 0.41–0.95) decreased the risk of bladder cancer, which was consistent across smoking groups, although its SNP did not affect carcinogenesis in nonsmoking groups.
