| Gene | FLT3 |
| Variant | K614_G617del |
| Impact List | deletion |
| Protein Effect | gain of function - predicted |
| Gene Variant Descriptions | FLT3 K614_G617del results in the deletion of four amino acids in the protein kinase domain of the Flt3 protein from amino acids 614 to 617 (UniProt.org). K614_G617del results in increased Flt3 phosphorylation in culture (PMID: 37246158), and therefore, is predicted to lead to a gain of Flt3 protein function. |
