| Gene Variant Descriptions | KIT N822K lies within the activation loop in the protein kinase domain of the Kit protein (PMID: 24205792). N822K results in constitutive activation of Kit, increased Erk1/2 and Stat3 phosphorylation, is transforming in culture (PMID: 24205792, PMID: 31484543), leads to mislocalization of Kit to endolysosomes (PMID: 31484543), and has been identified as a secondary mutation associated with imatinib resistance (PMID: 18488160). |
