Furthermore, because D816V is one of the diagnostic criteria for SM, it is clinically relevant to determine whether the mutation is present. 2008-01-01 The proto‐oncogene C‐KIT encodes a tyrosine kinase receptor that is expressed on mast cells and haematopoietic stem cells and can show somatic mutations in patients with mastocytosis. Only scattere Mutation analysis of C‐KIT in patients with myelodysplastic syndromes without mastocytosis and cases of systemic mastocytosis - Fritsche‐Polanz - 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. 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.

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, 99(5), 1741-1744. 25. Ma Y, Zeng S, Metcalfe DD, et al 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 … The c-KIT gene mutation creates an overgrowth of one cell line of mast cells. This clonal expansion of mast cells leads to areas of abnormal skin that easily reddens, swells and itches. The c-KIT mutation can also lead to the proliferation of mast cells within the bone marrow, resulting in systemic mastocytosis.

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.

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. Kit and c-kit mutations in mastocytosis: a short overview with special reference to novel molecular and diagnostic concepts.
