“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.

Mastocytosis represents a clonal proliferation of mast cell hematopoietic progenitors caused by gain-of-function mutations of the c- kit gene. The heterogeneity of c- kit mutations may have contributed to difficulties in characterizing genotype-phenotype correlation of the disease. 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. 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 The c-KIT mutation can also lead to the proliferation of mast cells within the bone marrow, resulting in systemic mastocytosis. In some cases, the genetic disorder is inherited, but in most cases, it is spontaneous, and there is no family history of mastocytosis. What are mast cells?

Imatinib mesylate is a potent inhibitor of c‐kit receptor tyrosine kinase activity. Ma, Y, Zeng, S, Metcalfe, DD, Akin, C, Dimitrijevic, S, Butterfield, JH, McMahon, G & Jack Longley, B 2002, ' 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. Familial mastocytosis is a well‐documented but rare entity, with fewer than 100 cases reported in the literature.

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.
