Abstract

Background A previously reported genome-wide association study (GWAS) of polycystic ovary syndrome (PCOS) in Han Chinese found that several loci of p value around 10e-5 warrant investigation. Replication of the GWAS was applied in this study to determine whether gene YAP1 (yeast associated protein 1) is associated with PCOS.

Methods An independent set of 1115 PCOS patients and 1137 controls were recruited; single nucleotide polymorphisms (SNPs) rs11225138, rs11225161, and rs11225166 from YAP1 were selected for the replication study. Real-time quantitative PCR was applied for genotyping by TaqMan-MGB probe assay.

Results Meta-analysis showed that the allele frequency of rs11225161 (A/G) was significantly different between PCOS and controls at a GWA significance (Pmeta =3.98e-09). Genotype–phenotype correlation study found 30 min and 60 min glucose of the oral glucose tolerance test were higher in PCOS patients with rs11225161 risk allele A. The G allele of SNP rs11225138 (G/C) was a further risk factor for higher luteinising hormone level in PCOS patients (p=0.041).

Conclusion YAP1 appears to be a new susceptibility gene for PCOS in Han Chinese women.
