On the other hand, the TT genotype of IL-8 polymorphism, GA and AA genotypes of TNF c.-418G>A polymorphism, and GA genotype of TNF c.-488G>A polymorphism significantly reduced breast cancer risk (IL-8 TT OR 0.48, 95% CI 0.33-0.72, P < 0.001; TNF c.-418 GA OR 0.58, 95% CI 0.41-0.80, P = 0.001; TNF c.-418 AA OR 0.38, 95% CI 0.14-0.98, P = 0.044; TNF c.-488 GA OR 0.68, 95% CI 0.48-0.96, P = 0.029). The gene discussed is TNF; the disease is breast carcinoma.
