We also found significant correlation between the Ala carrier of PARP-1 V762A polymorphism and increased risk of cervical cancer (dominant model: OR = 1.26, 95% CI = 1.06–1.50; allele model: OR = 1.31, 95% CI = 1.16–1.48) and gastric cancer (dominant model: OR = 1.33, 95% CI = 1.14–1.55; heterozygous model: OR = 1.28, 95% CI = 1.09–1.51). The gene discussed is PARP1; the disease is gastric cancer.
