Impact List | missense |
Protein Effect | gain of function - predicted |
Gene Variant Descriptions | KIT F522C lies within the transmembrane domain of the Kit protein (PMID: 15070706). F522C results in ligand independent autophosphorylation of Kit in cell culture (PMID: 15070706), and therefore, is predicted to lead to a gain of Kit protein function. |
