XPC and urinary bladder carcinoma: Our pooling data from eight case–control studies showed the genetic correlation between XPC rs2228000 and increased risk of bladder cancer under the allelic, homozygotic, heterozygotic, dominant, and recessive models, which is partly consistent with the positive data of He et al. (2013) [15] under the homozygotic and recessive models from four case–control studies.
