| Gene Variant Descriptions | FGFR2 P253R lies within the extracellular domain of the Fgfr2 protein (UniProt.org). P253R results in transformation activity similar to wild-type Fgfr2 in one study (PMID: 34272467), but a growth advantage relative to wild-type Fgfr2 in a competition assay (PMID: 34272467), loss of ligand specificity, activation of the p38/MAPK pathway in transgenic mouse models, and is transforming in cell culture (PMID: 11121055, PMID: 20175913, PMID: 23786770), and therefore, is predicted to lead to a gain of Fgfr2 protein function. |
