Association of +45G15G(T/G) and +276(G/T) polymorphisms in the ADIPOQ gene with polycystic ovary syndrome among Han Chinese women.Zhang N, Shi YH, Hao CF, Gu HF, Li Y, Zhao YR, Wang LC, Chen ZJ Reproductive Medical Center, The Affiliated Yantai Yuhuangding Hospital of Qingdao University Medical College, Yantai, People's Republic of China. OBJECTIVE: Polycystic ovary syndrome (PCOS) is frequently associated with insulin resistance (IR) and consequently with increased risk of metabolic disorders. Adiponectin is the most abundant adipocytokine and may play a role in the regulation of insulin sensitivity and IR in PCOS. The aim of the present study was to evaluate the genetic influence of the adiponectin (ADIPOQ) gene polymorphisms in the development of PCOS among Han Chinese women. METHODS: Two single nucleotide polymorphisms (SNPs),+45G15G(T/G) and +276(G/T), in the ADIPOQ gene were genotyped in 120 patients with PCOS and 120 healthy control subjects. All of them were Han Chinese women. RESULTS: Both SNPs were found to be significantly associated with PCOS (P=0.021, odds ratios=1.629, 95% confidence intervals: 1.074-2.469 and P=0.015, 1.576, 1.091-2.279 respectively). In SNP +276(G/T), the allele G was found to be significantly associated with increased fasting insulin levels, homeostasis model assessment to assess IR index, and area under the curve glucose levels, but decreased glucose and insulin ratio in the PCOS patients. Furthermore, the patients carrying genotypes G/G and G/T had significantly decreased levels of serum adiponectin (6.16+/-3.18 plus 5.93+/-3.23 vs 8.96+/-3.21 microg/ml, P=0.030) compared with the patients with genotype T/T. CONCLUSIONS: The present study provides evidence that SNPs +45G15G(T/G) and +276(G/T) in the ADIPOQ gene are associated with PCOS in Han Chinese women. SNP +276(G/T) may contribute to an impact of insulin levels and IR, which are implicated in the susceptibility for PCOS. Published 30 January 2008 in Eur J Endocrinol, 158(2): 255-60.
