APEX1 and cervical carcinoma: A positive association was observed between the polymorphisms of XRCC1 genes, that is, in codons 194 (P=0.03, odds ratio (OR) =2.39, 95% confidence interval (CI)=5.2–1.1), 280 (P=0.01, OR=4.1, 95% CI=11.5–1.3) and 399 (P=0.01, OR=3.4, 95% CI=8.6–1.3) while APE-1 genotype GG (p=0.03,odds ratio(OR)=0.2,95% confidence interval (CI)=0.97-0.004) we observed a statistically significant protective role in developing cervical cancer.
