However, a wide range of symptoms has been reported among individuals with the associated syndrome, many of which can be rather common, so it is difficult to know who has it from symptoms alone. Associations with a variety of clinical symptoms including gastric reflux, joint hypermobility, dysautonomia, flushing and pruritus, and hymenoptera allergy have variably been described in prior reports. Because tryptase is made by mast cells, and many symptoms seen among individuals with the hereditary alpha tryptasemia syndrome have been associated with the release of mast cell-derived mediators such as histamine, several of the clinical approaches used to treat the results of mast cell activation including antihistamines may be used and often are helpful.
