| Protein Effect | gain of function |
| Gene Variant Descriptions | FGFR2 S351C lies within Ig-like C2-type domain 3 of the Fgfr2 protein (UniProt.org). S351C leads to a gain of Fgfr2 protein function as indicated by decreased serum dependency for growth and anchorage-independent colony formation in culture (PMID: 40526877). |
