A novel single nucleotide polymorphism of INSR gene for polycystic ovary syndrome.
OBJECTIVE
To investigate several single nucleotide polymorphisms (SNPs) in the insulin receptor (INSR) gene that have significant associations with pathogenesis of polycystic ovary syndrome (PCOS) in a Korean population.


METHODS
Case-control study.


METHODS
University-based hospital.


METHODS
134 patients with PCOS and 100 healthy women as controls.


METHODS
All exons of INSR in DNA samples from 100 healthy women and 134 women with PCOS were sequenced and compared.


METHODS
Frequencies of genotypes for several SNPs in INSR gene that were found as specifically expressed SNPs in a Korean population.


RESULTS
Among nine SNPs analyzed in a large population, the genotypic frequencies of eight SNPs were similar, and they had no statistically significant association with PCOS. However, the frequency of a minor allele for one novel SNP, +176477 C>T, was higher in the control group than the patient group.


CONCLUSIONS
Among the analyzed SNPs, +176477 C>T, a novel SNP in the INSR gene, was associated with the pathogenesis of PCOS in a Korean population.
