Mastocytosis associated with a rare germline KIT K509I mutation displays a well-differentiated mast cell phenotype.

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.

2018-02-22 · Mastocytosis is usually caused by changes (known as variations or mutations) in the KIT gene. Most cases are caused by somatic mutations, meaning they only occur in certain parts of the body and are not inherited or passed on to the next generation. However, mastocystosis can rarely affect more than one person in a family.

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 A c-kit Mutation in Exon 18 in Familial Mastocytosis. Journal of Investigative Dermatology, 2013. Robert Loewe factor receptor c-kit or the c-kit ligand stem cell factor are mast cell deﬁcient.24 Recent data have shown that c-kit may be mutated in patients with mastocytosis.25 In fact, distinct “gain of function” point muta-tions in the catalytic domain of c-kit cause autophosphorylation of the receptor and stem cell factor independent growth of mast Garcia-Montero AC, Jara-Acevedo M, Teodosio C, Sanchez ML, Nunez R, Prados A, et al. KIT mutation in mast cells and other bone marrow hematopoietic cell lineages in systemic mast cell disorders: a prospective study of the Spanish Network on Mastocytosis (REMA) in a series of 113 patients. 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 Worobec, AS, Semere, T, Nagata, H, Metcalfe, DD: 1998, Clinical correlates of the presence of the Asp816Val c-kit mutation in the peripheral blood mononuclear cells of patients with mastocytosis.

When this receptor binds to stem cell factor (SCF) it forms a dimer that activates its intrinsic tyrosine kinase activity, that in turn phosphorylates and activates signal transduction molecules that propagate the Chronic myelogenous leukemia with acquired c-kit activating mutation and transient bone marrow mastocytosis.
