This review provides an overview of the clinical and translational studies that have identified HT as a modifier of mast cell-associated disorders and anaphylaxis and discusses mechanisms that may potentially explain some of these clinical findings. 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.
