| Gene Variant Descriptions | FGFR2 S252W lies within the extracellular domain of the Fgfr2 protein (UniProt.org). S252W results in a growth advantage relative to wild-type Fgfr2 in a competition assay and transformation activity similar to overexpressed Fgfr2 in cultured cells (PMID: 34272467), and results in decreased serum dependency for growth (PMID: 40526877), loss of ligand specificity, increased Fgfr2 phosphorylation, increased FGF7-stimulated shedding of HB-EGF, and is transforming in cell culture (PMID: 11121055, PMID: 18552176, PMID: 37759450). |
