A meta-analysis on the association between PPAR-? Pro12Ala polymorphism and polycystic ovary syndrome.


ABSTRACT: PURPOSE: To investigate the influence of the peroxisome proliferator activated receptor gamma (PPAR-?) Pro12Ala polymorphism on the susceptibility of polycystic ovary syndrome (PCOS) and body mass index (BMI), fast insulin levels, homeostasis model assessment of insulin resistance (HOMA-IR) in PCOS patients. METHODS: PubMed, EMBASE, MEDLINE and CENTRAL databases were searched to identify eligible studies. We then conducted a meta-analysis to examine the association between Pro12Ala polymorphism and PCOS. RESULTS: Seventeen eligible studies, including 2,149 patients and 2,124 controls were enrolled in this meta-analysis. Pro12Ala polymorphism was significantly associated with the susceptibility of PCOS (odds ratio [OR] 0.74, 95 % confidence interval [CI] [0.61, 0.90] for allele; OR 0.70, 95 % CI [0.57, 0.86] for genotype). In the European subgroup of PCOS, the X/Ala genotype was associated with lower BMI (mean difference [MD] -1.08, 95 % CI [-2.08, -0.09]) and fast insulin levels (MD -19.82, 95 % CI [-34.07, -5.58]). However, this polymorphism did not display an impact on HOMA-IR in PCOS patients. CONCLUSIONS: Ala variant would decrease the risk of PCOS and result in lower BMI and fast insulin levels in a European population, but had no impact on HOMA-IR in PCOS patients. Further studies are required to elucidate these associations more clear.
