The genotype IL-6 distribution did differ between the control group (CC 9.6%, GC 63.4%, GG 27.0%) and the PCOS patients (CC 4.7%, GC 29.4%, GG 65.9%) (p<0.001).
Sequence analyses of the PPAR gamma gene indicated that neither the common polymorphisms P12A or H478 H, nor novel polymorphisms (E79Q, V32G, -39 T>C, c.480 +33 t > g,) or unique sequence variations (S22S, A23A, T41A, S226C, K272 T, I484I, c.819 +24 a>c) detected in this investigation revealed evidence for a direct association of PPAR gamma with altered IL-7, IL-1beta, IL-6 and TNFalpha levels in PCOS patients.
A common polymorphism of the IL6 promoter, although not associated with the presence of PCOS, is associated with the clinical characteristics of women affected by this condition.
