KIT D816 Mutation Analysis (Mastocytosis) - Point mutation of the KIT oncogene at codon 816 (D816V) is seen in >90% of systemic mastocytosis (SM) cases. 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 …

Féger F(1), Ribadeau Dumas A, Leriche L, Valent P, Arock M. Author information: (1)Cellular and Molecular Hematology Unit, Faculty of Pharmacy, Paris, France. Most cases of mastocytosis are caused by a change (known as variation or mutation) in the KIT gene. This gene provides instructions to the body to make a protein that helps control many important cellular processes such as cell growth and division, survival, and movement. Detection of the c-kit D816V mutation in systemic mastocytosis by allele-specific PCR A sensitive, specific and cost-effective assay to detect the D816V mutation in archived formalin-fixed paraffin-embedded tissues from cases of SM has been developed. Mastocytosis represents a clonal proliferation of mast cell hematopoietic progenitors caused by gain-of-function mutations of the c-kit gene.

#5458). Sequencing the c-KIT gene by PCR in the skin biopsies from patients III 6 and her niece IV 1 (Figures 1 and 2b) showed a mutation in exon 18 at position 849 (S849I), which, to our knowledge, is previously unreported. A second mutation in exon 18 at position 835 (c-Kit M835K) was found exclusively in the most severely affected patient IV 1.

1741-1744. Familial mastocytosis is a well‐documented but rare entity, with fewer than 100 cases reported in the literature. The etiology has most commonly been linked to activating c‐kit mutations, with several mutations reported to date. We present a novel familial mastocytosis‐associated c‐kit mutation (R634W) in three siblings with urticaria pigmentosa.
