Aims: The c-kit D816V activating mutation is found in >80% of cases of systemic mastocytosis (SM) and represents a potential drug target. Furthermore, because D816V is one of the diagnostic criteria for SM, it is clinically relevant to determine whether the mutation is present. 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.

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

The presence of KIT D816V mutation is one of the minor criteria for diagnosis of SM and mutation testing can assist in diagnosis, particularly in limited specimens. KIT D816 mutations, including D816V, D816H and D816Y, are also the most common KIT … the entire coding sequence of c-KIT mRNA from cutaneous lesions of 50 children between 0 and 16 years of age with sporadic or familial 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. KITVS - Overview: KIT Asp816Val Mutation Analysis, Varies. Web: mayocliniclabs.com.

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.

Cutaneous mastocytosis samples are indicated in italics. (d) SM samples The majority of patients with familial mastocytosis do not have a c-KIT mutation.
