Gene Symbol
Entrez Gene ID
Gene Name
Fms-related tyrosine kinase 1
Chromosomal Location
This gene encodes a member of the vascular endothelial growth factor receptor (VEGFR) family. VEGFR family members are receptor tyrosine kinases (RTKs) which contain an extracellular ligand-binding region with seven immunoglobulin (Ig)-like domains, a transmembrane segment, and a tyrosine kinase (TK) domain within the cytoplasmic domain. This protein binds to VEGFR-A, VEGFR-B and placental growth factor and plays an important role in angiogenesis and vasculogenesis. Expression of this receptor is found in vascular endothelial cells, placental trophoblast cells and peripheral blood monocytes. Multiple transcript variants encoding different isoforms have been found for this gene. Isoforms include a full-length transmembrane receptor isoform and shortened, soluble isoforms. The soluble isoforms are associated with the onset of pre-eclampsia.

This review concluded that VEGF may have a strategic role in the pathophysiology of PCOS and is the key mediator in the pathogenesis of ovarian hyperstimulation syndrome (OHSS) in women undergoing assisted reproductive procedures. Its role is perhaps not singular and several other factors such as the bioavailability of its soluble receptor sFlt-1 and a multidisciplinary orchestration of other cytokines and growth factors may be involved in the pathophysiology of PCOS and OHSS.
