Association of genetic variations in genes involved in glutathione metabolism with risk of development of uterine fibroids

Abstract

A total of 552 females with uterine fibroids and 337 age-matched healthy controls were recruited for the study. Genotyping of single nucleotide polymorphisms (SNPs) of rs713041 GPX4, rs4902346 GPX2, rs41303970 GCLM, rs17883901 GCLC, rs1050450 GPX1, rs1799811 and rs1695 GSTP1, rs2551715 GSR, rs1801310 GSS, rs4820599 GGT1, rs7674870 SLC7A11 were done using Taq-Man-based assays. Genotyping of +/0 GSTM1 and +/0 GSTT1 polymorphisms were done using multiplex PCR. Polymorphism rs7674870 SLC7A11 was associated with increased risk of uterine fibroids (OR=1.25, 95%CI=1.03-1.50; p=0.02); rs2551715 GSR was associated with decreased risk of disease (OR=0.83, 95% CI=0.70-0.99; p=0.04)
