    Abstract:
    Several studies have been conducted to examine the association between PPAR-γ2 Pro12Ala polymorphism and polycystic ovary syndrome (PCOS), but the results remain inconsistent. To make a more precise estimation of the relationship, a meta-analysis was performed. In the current meta-analysis, a total of 17 case-control studies, including 2176 cases and 2373 controls, were selected. Odds ratios (ORs) and 95% confidence intervals (CIs) for Pro/Ala+Ala/Ala versus Pro/Pro genotype in all population and different nationality groups, and homeostasis model assessment-insulin resistance (HOMA-IR) of different genotype were evaluated. In the overall analysis, significant association between PPAR-γ2 Pro12Ala polymorphism and reduced risk of PCOS was observed (OR=0.75; 95%CI, 0.62-0.91; p=0.003). Stratified analysis showed that significantly strong association was presented only in Europeans (OR=0.74; 95%CI, 0.60-0.90; p=0.003), but not in Asians (OR=0.86; 95%CI, 0.51-1.43; p=0.56). Additionally, carrying the Ala12 allele was not associated with HOMA-IR in PCOS patients (OR=-0.29; 95%CI, -0.82-0.24; p=0.29). This meta-analysis supported that PPAR-γ2 Pro12Ala polymorphism was capable of reducing polycystic ovary syndrome risk in Europeans, but not in Asians.
