Conclusions
A SNP located in the HNF1A gene is associated with PCOS among Han Chinese women. This suggested that variations in HNF1A might confer risk for PCOS.
Methods
One thousand one hundred thirty-eight PCOS and 1125 healthy control Han Chinese women were recruited from Reproductive Hospital Affiliated to Shandong University. Serum hormone, blood lipid level, and genomic DNA were obtained from the peripheral blood for this research. Two single-nucleotide polymorphisms (SNPs)-rs2393791 and rs7305618-located in HNF1A were genotyped using the Sequenom MassARRAY system.
Purpose
This study aims to ascertain whether an association exists between hepatocyte nuclear factor 1 alpha (HNF1A) and polycystic ovary syndrome (PCOS).
Results
The allele frequencies of SNP rs7305618 had significant differences between PCOS patients and controls after adjusting for age and BMI (p = 0.023). Besides, PCOS patients carrying the rs7305618 CC genotype shown a higher testosterone level than the patients with CT + TT genotypes after being adjusted by age and BMI (p = 0.019). Conclusions: A SNP located in the HNF1A gene is associated with PCOS among Han Chinese women. This suggested that variations in HNF1A might confer risk for PCOS.
