| FLT3 | G697R | missense | unknown | FLT3 G697R lies within the protein kinase domain of the Flt3 protein (UniProt.org). G697R has been demonstrated to occur as a secondary resistance mutation in the context of FLT3 internal tandem duplication (FLT3-ITD) mutations (PMID: 15374944, PMID: 22875611, PMID: 17827387), but has not been biochemically characterized and therefore, its effect on Flt3 protein function is unknown (PubMed, Oct 2025). | Y |
| FLT3 | N676D | missense | unknown | FLT3 N676D lies within the protein kinase domain of the Flt3 protein (UniProt.org). N676D has been demonstrated to occur as a secondary resistance mutation in the context of FLT3 internal tandem duplication (FLT3-ITD) mutations (PMID: 22875611, PMID: 15374944), but has not been biochemically characterized and therefore, its effect on Flt3 protein function is unknown (PubMed, Oct 2025). | Y |
