Approximately >90% of adults and 40% of children also express this mutation whereas another 40% of children have mutations involving other areas of KIT. Furthermore, because c-kit mutations in cutaneous mastocytosis are normally a heterozygous state, the detection sensitivity of the particular mutations may depend on the substantial number of local mast cells with the mutated alleles and the amplification rate of the mutated alleles during the initial nonspecific amplification step in PCR. In these c-kit mutations are now considered to be of somatic cell origin.8,12 The exact contribution of c-kit mutations to the clinical course of mastocytosis re-mains unclear. In this study, we attempt to characterize the c-kit mutation profiles in patients with childhood-onset indolent mastocytosis, and extend genotype-phenotype correlation.

In most patients, a mutation is present in the gene for C‐KIT, resulting in deregulation of the c‐kit receptor. Imatinib mesylate is a potent inhibitor of c‐kit receptor tyrosine kinase activity.

By analyzing the clinical symptoms of members of the four generations of the concerned family, we assume that the c-KIT S849i mutation contributes to a rather benign phenotype of CM gradually, nevertheless incompletely resolving by age. 2020-10-04 · c-KIT is a proto-oncogene that encodes a type III transmembrane tyrosine kinase. c-KIT and its ligand stem cell factor have a key role in survival, proliferation, differentiation, and functional activation of hematopoietic progenitor cells. c-KIT mutations are reported in nearly all systemic mastocytosis, 20% to 40% core-binding factor (CBF) acute myeloid leukemia (AML), and approximately 20% The c-KIT mutation causing human mastocytosis is resistant to STI571 and other KIT kinase inhibitors; kinases with enzymatic site mutations show different inhibitor sensitivity profiles than wild-type kinases and those with regulatory-type mutations.
