Protein Effect | gain of function - predicted |
Gene Variant Descriptions | KIT D820A lies within the protein kinase domain of the Kit protein (UniProt.org). D820A has been demonstrated to occur as a secondary drug resistance mutation (PMID: 16954519, PMID: 31363162), and results in reduced Kit protein expression and stability, abnormal cellular localization, but constitutive Kit phosphorylation in the absence of Pkc in cell culture (PMID: 27440273), and therefore, is predicted to lead to a gain of Kit protein function. |
