BACKGROUND: Polycystic ovary syndrome (PCOS) is a complex endocrine-metabolic disorder. A previous genome-wide association study (GWAS) identified five single nucleotide polymorphisms (SNPs) which were independently associated with PCOS in Han Chinese. To overcome population stratification, a family-based analysis was conducted to validate whether these five SNPs are associated with PCOS. METHODS: A total of 276 family trios (828 participants) having a proband with PCOS were included in the family-based study. The transmission disequilibrium test (TDT) was used to analyze the association between PCOS and five SNPs rs13429458, rs12478601, rs13405728, rs10818854 and rs2479106 in three susceptible loci 2p16.3, 2p21 and 9q33.3. RESULTS: A positive association was observed for the SNP rs13429458 (P= 3.74 × 10(-5)). CONCLUSIONS: TDT confirms that SNP rs13429458, in the THADA gene, is significantly associated with risk of PCOS. This family-based analysis enhances our previous case-control GWAS and provides further support for the role of susceptibility loci in PCOS.
