FSHR gene polymorphisms influence bone mineral density and bone turnover in postmenopausal women

Abstract

The SNP rs6166 of the FSHR gene significantly influences BMD in postmenopausal women. In particular, AA rs6166 women are at increased risk of postmenopausal osteoporosis compared with GG rs6166 women, independently of circulating levels of FSH and estrogens. Previous studies have demonstrated that this SNP influences cell and tissue response to hyperstimulation of FSHR in vivo and in vitro. Our study results appear in agreement with these experimental data and with known biological actions of FSH/FSHR system in bone homeostasis.
