| Gene Variant Descriptions | KIT D816E lies within the protein kinase domain of the Kit protein (UniProt.org). D816E has been identified in the scientific literature (PMID: 29100343, PMID: 29093181, PMID: 35194937) but has not been biochemically characterized and therefore, its effect on Kit protein function is unknown (PubMed, Sep 2025). |
