FGF4（fibroblast growth factor 4），癌症关联基因，基因ID：2249，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。该基因通过其致癌转化活性鉴定。这个基因和另一种致癌生长因子fgf3，位于11号染色体上。两种基因在不同类型的人类肿瘤中同时扩增。对小鼠同源物的研究表明，通过声刺猬（shh）信号途径，在骨形态发生和肢体发育中发挥作用。[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. This gene was identified by its oncogenic transforming activity. This gene and FGF3， another oncogenic growth factor， are located closely on chromosome 11. Co-amplification of both genes was found in various kinds of human tumors. Studies on the mouse homolog suggested a function in bone morphogenesis and limb development through the sonic hedgehog (SHH) sign。
