| Gene Variant Descriptions | KIT D816F lies within the tyrosine kinase domain 2 of the Kit protein (PMID: 17555444). D816F results in constitutive phosphorylation of Kit and activation of Stat3, Mapk, and Akt signaling in cultured cells (PMID: 9990072, PMID: 16397263), and also confers resistance to imatinib in culture (PMID: 16397263). |
