Overall, the hOGG1 Ser326Cys polymorphism was not associated with lung cancer susceptibility in different genetic models (dominant model comparison: OR = 0.133; 95% CI = 0.111–0.161; Pheterogeneity = 0.000), and recessive model: OR = 0.543; 95% CI = 0.399–0.739; Pheterogeneity = 0.000). Here, OGG1 is linked to lung cancer.
