| Gene Variant Descriptions | KIT T417_D419delinsI results in the deletion of three amino acids in Ig-like C2-type domain 5 of the Kit protein from amino acids 417 to 419, combined with the insertion of an isoleucine (I) at the same site (UniProt.org). T417_D419delinsI results in ligand-independent dimerization (PMID: 25544564, PMID: 15618474), constitutive activation (PMID: 25544564, PMID: 27482095, PMID: 16015387), decreased cell surface Kit expression, altered degradation (PMID: 27482095), and SCF- and IL3-independent growth in culture (PMID: 27482095, PMID: 15618474). |
