Association Study of Gene LPP in Women with Polycystic Ovary Syndrome

Year: 2012

Type: article

Abstract: BACKGROUND: Previous genome-wide association study (GWAS) of polycystic ovary syndrome (PCOS) in Han Chinese population has found that SNPs in LPP gene were nominally significant in PCOS patients (P around 10E-05). Replication of the GWAS was applied to further confirm the relationship between LPP gene and PCOS. METHODS: Three polymorphisms of LPP gene (rs715790, rs4449306, rs6782041) were selected and replicated in additional 1132 PCOS cases and 1142 controls. Genotyping of LPP gene was carried out by Taqman-MGB method. RESULTS: In rs715790, the allele frequency is significantly different between the PCOS group and the control group. Meta-analysis showed that the allele frequencies of the three SNPs rs715790 (P(meta) =1.89E-05, OR=1.23), rs4449306 (P(meta) =3.0E-04, OR=1.10), rs6782041 (P(meta) = 2.0E-04, OR=1.09), were significantly different between PCOS cases and controls. CONCLUSIONS: Our results suggest that LPP gene might be a novel candidate for PCOS.
