The FTO (Fat mass and obesity associated) locus has recently been associated with obesity and type 2 diabetes (T2D) in humans. To understand the role of the FTO gene in polycystic ovary syndrome (PCOS) we genotyped single nucleotide polymorphism (SNP) rs1421085 (C/T) in women with PCOS (n=207) and controls (n=100) from a Central European population. The homozygous C/C genotype showed increased prevalence in PCOS patients either obese or with metabolic syndrome (MetS) compared to lean PCOS patients or controls (27.6%, 38.9%, 22.3%, and 16.3%, respectively). In logistic regression, this genotype strongly associated with MetS (P<0.0001, OR 3.2, 95% CI 1.8-5.7) and impaired fasting glucose (IFG) with P<0.0007, OR 7.7, 95% CI 2.1-28.6, independently of BMI or age, and to AUC(gluc) during OGTT (P<0.0001, alpha=0.99), indicating an influential role of the FTO gene in the glucose intolerance component of MetS.
FTO（与脂肪量和肥胖相关）基因座最近被发现与人类肥胖症和2型糖尿病（T2D）有关。为了了解FTO基因在多囊卵巢综合征（PCOS）中的作用，我们对来自中欧人群的PCOS患者（n = 207）和对照组（n = 100）的单核苷酸多态性（SNP）rs1421085（C/T）进行了基因分型。与体型偏瘦的PCOS患者或对照组相比，纯合C/C基因型在肥胖或患有代谢综合征（MetS）的PCOS患者中患病率更高（分别为27.6%、38.9%、22.3%和16.3%）。在逻辑回归分析中，该基因型与MetS（P<0.0001，OR 3.2，95%CI 1.8 - 5.7）和空腹血糖受损（IFG）显著相关（P<0.0007，OR 7.7，95%CI 2.1 - 28.6），独立于BMI或年龄，并且与口服葡萄糖耐量试验（OGTT）期间的AUC（葡萄糖）相关（P<0.0001，α = 0.99），表明FTO基因在MetS的葡萄糖不耐受成分中具有重要作用。
