To address the effect of hGGO1 (rs1052133) gene polymorphism on the risk of breast cancer, a meta-analysis was performed. We pooled adjusted odds ratios (OR) as overall and three subgroups (menopausal status, ethnicity, and study setting). In overall analysis, we found a significant association when the model of inheritance was homozygote (pooled OR 1.14; 95% CI 1.01, 1.29). Subgroup analysis showed significant association for homozygote genetic models among postmenopause women (OR 1.23; 95% CI 1.01, 1.49) and Asian population (OR 1.17; 95% CI 1.01, 1.35). This study suggested that the carrier of Ser326Cys polymorphism of hOGG1, Cys/Cys vs Ser/Ser, are at higher risk for breast cancer, independent of other hormonal and environmental risk factors.
