Polycystic ovary syndrome (PCOS) is one of the most common female endocrine disorders. The aim of this study was to investigate possible associations between 45T/G and 276G/T variants of the ADIPOQ gene and susceptibility to PCOS. A meta-analysis of 11 published case-control studies on the 45T/G variant of the ADIPOQ gene (involving a total of 1176 patients with PCOS and 1759 controls) and eight published case-control studies on the 276G/T variant of the ADIPOQ gene (involving a total of 895 patients with PCOS and 1024 controls) was performed. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to assess the strength of associations. The comparison of G vs. T in ADIPOQ 45T/G showed significant differential susceptibility to PCOS (OR=1.397, 95% CI 1.156-1.689). A significant association was also found between PCOS susceptibility and the comparison of G vs. T in ADIPOQ 276G/T (OR 0.812, 95% CI 0.704-0.937). However, protective effects were found in both sites under the co-dominant model for Caucasians. Further studies are warranted to assess these associations in greater detail, especially in Asian populations.
