该基因编码的蛋白是成纤维细胞生长因子（fgf）家族的一员。fgf家族成员具有广泛的有丝分裂和细胞存活活性，参与胚胎发育、细胞生长、形态发生、组织修复、肿瘤生长和侵袭等多种生物学过程。该基因突变与常染色体显性遗传性脑共济失调有关。另外，已经发现该基因的剪接转录变体。[由RefSeq提供，2008年7月]
The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. A mutation in this gene is associated with autosomal dominant cerebral ataxia. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2008]
