XPC and breast cancer: A recent case-control association study using tissue from 493 breast cancer and 387 control cases suggested an association between two XPC polymorphisms, rs2228001-A>C (Lys939Gln) and rs2733532-C>T, with an increased odds of breast cancer (107), and another study with 200 cases and controls suggested an association between the XPC PAT+ allele and higher odds of breast cancer (108).
