In fact, individuals with genotypes XPC PAT(+/+)/XPD 751Lys/Gln or XPC PAT(+/+)/XPD 751Gln/Gln showed a 1.63-fold (CI = 0.89–2.98), P = 0.111, and 2.25-fold (CI = 0.83–6.13), P = 0.202, higher risk of lung cancer, respectively, when compared with homozygous carriers of the wild type allele of both polymorphisms (XPC PAT(-/-)/XPD 751Lys/Lys). The gene discussed is ERCC2; the disease is lung cancer.
