| Protein Effect | gain of function - predicted |
| Gene Variant Descriptions | FLT3 Y599_D600insSTDNEYFYVDFREYEY results in the insertion of sixteen amino acids in the juxtamembrane domain of the Flt3 protein between amino acids 599 and 600 (UniProt.org). Y599_D600insSTDNEYFYVDFREYEY has not been biochemically characterized, but can be predicted to lead to a gain of Flt3 protein function based on the effects of other Flt3 internal tandem duplication (ITD) mutations (PMID: 12970773, PMID: 9737679, PMID: 11090077). |
