XPC and urinary bladder cancer: We previously studied 23 XPC SNPs in 547 bladder cancer cases and 579 controls, and found that homozygous carriage of the variant alleles of c.1496C > T (p.Ala499Val, rs2228000) and two 3'-untranslated region (UTR) polymorphisms, c.*611T > A (rs2470352) and c.*618A > G (rs2470458; previously named Ex15-184 and Ex15-177 respectively), was associated with increased bladder cancer risk [4].
