The clinical behavior of systemic mastocytosis (SM) is strongly associated with activating mutations in KIT (D816V in >80% of cases), with the severity of the phenotype influenced by additional somatic mutations, for example, in SRSF2, ASXL1, or RUNX1.

Although hymenoptera-induced anaphylaxis is not primarily a mast cell-driven hematological disorder, the latter is present in a significant proportion of patients and has to be excluded by basal serum tryptase determination, skin inspection as well as exclusion of systemic mastocytosis by D816V mutation analysis in peripheral blood and/or bone marrow examination in selected patients.
