Gene Variant Descriptions | FGFR3 R248C lies within the extracellular domain of the Fgfr3 protein (UniProt.org). R248C confers a gain of function to the Fgfr3 protein as demonstrated by constitutive ligand-independent cell proliferation (PMID: 19381019) and increased activation of the Mapk signaling pathway (PMID: 24626198). |
