Clinical presentation and genetics

Systemic mast cell activation disease (MCAD) denotes a group of primary mast cell disorders characterized by aberrant release of variable subsets of mast cell mediators and/or accumulation of pathological mast cells in potentially any or all organs and tissues. The clinical presentation of MCAD is very diverse, since due to both the widespread distribution of mast cells and the great heterogeneity of aberrant mediator expression patterns, symptoms can occur in virtually all organs and tissues. According to the current classification of MCAD the traditionally recognized rare variant termed systemic mastocytosis (SM) is characterized by specific pathological somatic mutations in exon 17 of the tyrosine kinase KIT (for which KITD816V accounts for the great majority) and immunohistochemical findings (known as the

World  Health Organization (WHO) criteria) caused by these mutations. The other variant, only recently recognized, is termed mast cell activation syndrome (MCAS; seemingly borne of a large collection of mutations in various genes) and presents a complex clinical picture of multiple proven mast cell mediator-induced symptoms (relevant differential diagnoses exluded) and failure to meet the WHO criteria for diagnosis of SM. Recent findings suggest that MCAS is a fairly common disorder in contrast to SM. According to recent findings, the variants and clinical subtypes of MCAD do not represent distinct disease entities but should be more accurately regarded as varying compositions of a common process of mast cell dysfunction. Although almost all mutations causing MCAD were somatic rather than germline, evidence was provided for common familial occurrence of MCAD. Irrespective of systemic MCAD variant and gender, around 75% of the index patients had at least one first-degree relative with MCAD. The molecular processes which result in familial aggregation of MCAD remain speculative. The detection of differing systemic MCAD-associated somatic mutations within given families suggests that the disease arises secondary to a dysfunction of as yet unidentified operator and/or regulator genes.
