The c-kit gene is located on chromosome 4 q11–12. 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.

Overall, 86% of the patients had mutations in c-KIT. The D816V mutation was present in 35% of the children, including two of four children with a familial form of the disease. We also found two Background: Cutaneous mastocytosis (CM) is a heterogeneous disease that commonly presents with skin lesions in childhood.

Mastocytosis represents a clonal proliferation of mast cell hematopoietic progenitors caused by gain-of-function mutations of the c- kit gene.

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. 2005-05-01 · A number of reports have demonstrated germline mutations within exon 11 of c-kit in mastocytosis with multiple gastrointestinal stromal tumors. 16, 18 In contrast, Sommer and colleague 19 have failed to reproduce any of clinical phenotypes of cutaneous mastocytosis by introducing the same c-kit heterozygous mutation (Val558X) into mice.

KIT mutation analysis in mast cell neoplasms: recommendations of the European Competence Network on Mastocytosis.

KIT is a receptor tyrosine kinase type III, which binds to stem cell factor (a substance that causes certain types of cells to grow), also known as "steel factor" or "c-kit ligand". 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

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? Mutations of the gene coding for the c-kit receptor (mutation KIT (D816V)), leading to constitutive signalling through the receptor is found in >90% of patients with systemic mastocytosis.
