267 Familial Cases of Mast Cell Disease

Abstract: Elevated mast cell numbers have been implicated in a wide range of clinical conditions, from allergic rhinitis and asthma to systemic mastocytosis. Familial etiologies for mast cell disease have been suggested including defects in c-kit regulation.PurposeTo evaluate a family with multiple presentations of probable mast cell disease.MethodsA case review of a family cohort is presented.SummaryThe index case, a 26-year-old Caucasian male, was initially followed at our institution for reversible airway obstruction… Show more

“…Similarly, in three of the five previous case reports on familial MCAD variability in the disease subtype, the severity of mediator-related symptoms, and the age at clinical onset within the MCAD sufferers has been described [9], [12], [23]. In four of those five case reports [10][13] functionally activating somatic point mutations were identified in mast cells which, however, were homotypic, i.e.…”

“…To date, only five familial cases (three SM and two MCAS) have been reported [9][13]. A systematic investigation of familial clustering would be an important step towards defining the contribution of inherited genetic factors to the risk of systemic MCAD.…”

“… and Bursztein et al . 2009 . The prevalence of systemic MCAD among the first‐degree relatives in our sample was 33% (Figure ), which differed significantly ( P < 0·0001; Fisher′s exact test) from the prevalence in the control group (around 14%; Figure ).…”

“…In a second SM family, a functionally activating mutation in Kit exon 8, which resulted in the deletion of codon 419, was detected in the three affected patients (mother, daughter, granddaughter) but not in the healthy sister . One MCAS family has also been reported in which the father and his two children (daughter and son) presented with varying clinical features . However, the underlying genetic alterations were not investigated.…”
