Summaries for FST Gene

Entrez Gene Summary for FST Gene

  • Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release. The single FST gene encodes two isoforms, FST317 and FST344 containing 317 and 344 amino acids respectively, resulting from alternative splicing of the precursor mRNA. In a study in which 37 candidate genes were tested for linkage and association with polycystic ovary syndrome (PCOS) or hyperandrogenemia in 150 families, evidence was found for linkage between PCOS and follistatin.

GeneCards Summary for FST Gene

FST (Follistatin) is a Protein Coding gene. Diseases associated with FST include polycystic ovary syndrome and endometriosis. Among its related pathways are Signaling by GPCR and Integrated Pancreatic Cancer Pathway. GO annotations related to this gene include signal transducer activity and activin binding. An important paralog of this gene is FSTL3.
