| Impact List | deletion |
| Protein Effect | unknown |
| Gene Variant Descriptions | FLT3 D593del results in the deletion of an amino acid in the juxtamembrane domain of the Flt3 protein at amino acid 593 (PMID: 14759363). D593del has been identified in the scientific literature (PMID: 40196870), but has not been biochemically characterized and therefore, its effect on Flt3 protein function is unknown (PubMed, Sep 2025). |
