Overview

NCI Definition: A variant of mastocytosis characterized by multifocal, dense infiltrates of mast cells (15 or more mast cells in aggregates) detected in the bone marrow and/or other extracutaneous sites. (WHO, 2001) -- 2003 [1]

Systemic mastocytosiss most frequently harbor alterations in KIT, ASXL1, TET2, ETV6, and CDKN2A [2].

Most Commonly Altered Genes in Systemic Mastocytosis

KIT Mutation (somatic), KIT Mutation, KIT D816V, KIT Codon 816 Missense, and ASXL1 Mutation are the most common alterations in systemic mastocytosis [2].
