Official Full Name: fibroblast growth factor 20
Also known as: RHDA2; FGF-20
The protein encoded by this gene is a member of the fibroblast growth factor family. Fibroblast growth factors have a wide range of mitotic and cell survival activities, and participate in various biological processes such as embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. The gene product is a secreted neurotrophic factor but lacks a typical signal peptide. It is expressed in the normal brain, especially the cerebellum, and may regulate central nervous system development and function. Homodimerization of this protein was shown to modulate its receptor binding activity and concentration gradient in the extracellular matrix. Genetic variation in this gene has been linked to susceptibility to Parkinson's disease.
