In the study by Sugimura et al.22), the significant association between the Cys/Cys genotype of OGG1 and lung cancer risk was observed only for squamous cell carcinoma (n=l 18), and a slightly elevated insignificant OR for adenocarcinoma of the lung (n=78) was also documented. The gene discussed is OGG1; the disease is lung adenocarcinoma.
