The GSTP1 A/G gene polymorphism was not associated with RCC risk in the overall population, Asians and Caucasians, hospital-based controls, or population-based controls (overall population: A allele: OR = 0.93, 95% CI: 0.77–1.11, P = 0.41; AA genotype: OR = 0.74, 95% CI: 0.55–1.00, P = 0.05; GG genotype: OR = 1.14, 95% CI: 0.93–1.14, P = 0.22; Table 4). The gene discussed is GSTP1; the disease is renal cell carcinoma.
