XRCC1 and cervical carcinoma: In the light of these conflicting data we examined the genotypic frequency of XRCC1 gene and APE gene in a case-control study, The SNPs chosen for analysis were XRCC1 (Arg194Trp, Arg280His, Arg399Gln) and APE-1 Asp/148 Glu, The results indicated that the association with respect to His 280 genotype were significantly increased in relation to the relative risk of cervical cancer.
