| Protein Effect | unknown |
| Gene Variant Descriptions | KIT D419del results in the deletion of an amino acid in Ig-like C2-type domain 5 of the Kit protein at amino acid 419 (UniProt.org). The functional effect of D419del is conflicting, as D419del has been reported to result in ligand-independent phosphorylation of Kit (PMID: 16143141, PMID: 15618474), and to result in lack of Kit phosphorylation and lack of cytokine-independent growth in cell culture (PMID: 31182436), and leads to Kit inactivation in response to Ptpre similar to wild-type Kit in cultured cells (PMID: 33732906), and therefore, its effect on Kit protein function is unknown. |
