Some XPD polymorphisms have been suggested to modulate DNA repair capacity and promote tumorigenesis [28]. XPD Asp312Asn (rs1799793) was related to prostate cancer pathology [29]. XPD Lys751Gln (rs13181) polymorphism could increase the susceptibility of such cancers [30]. The gene discussed is ERCC2; the disease is prostate carcinoma.
