ERCC2 and urinary bladder carcinoma: The A allele of XPD Arg156Arg (C22541A) and the C allele of XPD Lys751Gln (A35931C) are associated with increased risk of bladder cancer (adjusted OR = 1.54, 95% CI 1.19–2.01 and 1.65, 1.12–2.73 respectively). XPD156, AA genotype showed a significant increase for bladder cancer versus CC and AC genotype (adjusted OR = 1.58, 95% CI 1.20–2.08). For XPD751, AC genotype showed a significant increased bladder cancer risk versus the homozygous wild genotype (AA adjusted OR = 1.86 95% CI 1.13–3.04)
