FGF3（fibroblast growth factor 3），癌症关联基因，基因ID：2248，该基因编码的蛋白是成纤维细胞生长因子家族的成员。FGF家族成员具有广泛的有丝分裂和细胞存活活性，并参与多种生物学过程，包括胚胎发育、细胞生长、形态发生、组织修复、肿瘤生长和侵袭。该基因与小鼠乳腺肿瘤病毒诱导的原癌基因fgf3/int-2相似。这种基因在人类肿瘤中频繁扩增，可能对肿瘤的转化和肿瘤的进展具有重要意义。对小鼠和鸡的相似基因的研究表明它们在内耳形成中的作用。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 similarity with mouse fgf3/int-2， a proto-oncogene activated in virally induced mammary tumors in the mouse. Frequent amplification of this gene has been found in human tumors， which may be important for neoplastic transformation and tumor progression. Studies of the similar genes in mouse and chicken suggested the role in inner ear formation.关联癌症：乳腺癌，肝细胞癌。关联化疗。
