OGG1 and breast cancer: Furthermore, the GG genotype frequency of OGG1-rs1052133 polymorphism revealed a nominal association with lower risk of breast cancer in the recessive model (GG vs. CC/CG, OR: 0.23, 95% CI: 0.05–1.11, p = 0.0465, with the trend confirmed in the codominant model for GG genotype (p = 0.05).
