However, the results indicated that the IL-6 (−174 G/C) polymorphism was marginally associated with PCOS in the allelic model (C vs. G: OR = 0.63, 95% CI = 0.41–0.96) and by homozygote comparison (CC vs. GG: OR = 0.52, 95% CI = 0.30–0.93). The gene discussed is IL6; the disease is polycystic ovary syndrome.
