Gene Description | FGFR3, fibroblast growth factor receptor 3, is a receptor tyrosine kinase activated upon binding of the FGF ligand, which activates RAS-MAPK and PI3K-AKT pathways (PMID: 22508544). Altered function of FGFR3 in cancer may lead to increased cell proliferation and decreased apoptosis (PMID: 22508544) and mutations and fusions are commonly observed in bladder cancer (PMID: 30975452, PMID: 23175443), while FGFR3 overexpression only in bladder cancer may have different treatment implications (PMID: 32682615). | ||||||||||
