“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,” Blood, vol. 99, no. 5, pp. 1741–1744, 2002. 2005-07-14 A c-kit Mutation in Exon 18 in Familial Mastocytosis Jou rnal of Inve stigat ive Dermato log y (201 3) 133, 839–8 41; doi:10 .1038/ jid. 2012 .394; publishe d onli ne 29 Novem ber 2012 TO TH E Mastocytosis is characterized by the abnormal proliferation of mast cells in 1 or more organs.

The etiology has most commonly been linked to activating c‐kit mutations, with several mutations reported to date. We present a novel familial mastocytosis‐associated c‐kit mutation (R634W) in three siblings with urticaria pigmentosa. mastocytosis S849i c-KIT mutation M835K c-KIT mutation Normal bone marrow Figure 1. The family’s pedigree.

Mastocytosis is characterized by the abnormal proliferation of mast cells in 1 or more organs. 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.

18 May 2017 Various activating mutations within KIT have been associated with systemic mastocytosis, with p.Asp816Val (D816V) being the most common, cally the mutated c-kit and/or its intracellular signaling. J. Leukoc.

The Background: Cutaneous mastocytosis (CM) is a heterogeneous disease that commonly presents with skin lesions in childhood. Objective: In this study, we aimed to evaluate the clinical and laboratory test results of our patients with CM to ascertain prognostic factors by using patients' long-term follow-up results and to determine c-KIT (receptor tyrosine kinase) mutation from peripheral blood Bi-directional sequencing of KIT exons 8, 9, 11, 13 and 17 for detection of activating mutations including the common mutation D816V. For solid tumors, tumor enrichment is performed before extraction.

Imatinib (a tyrosine kinase receptor inhibitor) may be useful when treating adults with aggressive systemic mastocytosis but is ineffective in patients with the D816V c-kit mutation. Midostaurin (a 2nd-generation tyrosine kinase receptor inhibitor) can be used to treat adults with aggressive systemic mastocytosis, systemic mastocytosis with associated hematologic disorders, or mast cell leukemia.

The most common c-kit mutation in mastocytosis is D816V and is believed to cause the abnormal proliferation and accumulation of mast cells in tissues. 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.
