| Gene Variant Descriptions | FGFR2 N550D (corresponds to N549D in the canonical isoform) lies within the protein kinase domain of the Fgfr2 protein (UniProt.org). N550D (reported as N549D) results in growth factor-independent growth in a high-throughput cell culture assay (PMID: 41361008), and therefore, is predicted to lead to a gain of Fgfr2 protein function. |
