Genes affected

FSHR (HGNC:3969): (follicle stimulating hormone receptor) The protein encoded by this gene belongs to family 1 of G-protein coupled receptors. It is the receptor for follicle stimulating hormone and functions in gonad development. Mutations in this gene cause ovarian dysgenesis type 1, and also ovarian hyperstimulation syndrome. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2010]

FSHR is highly expressed in Granulosa cells and is tightly associated with regulation of follicle development in response to FSH stimulation. Structurally alterations in FSHR may lead to inactivaion of the receptor and cause primary ovarian insufficiency (POI). -
