GARD does not currently have information about the cause of this condition. Some individuals may demonstrate an increase in tryptase concentrations above baseline after anaphylaxis or allergen challenge while remaining below 11.5 ng/mL; measurement of tryptase in specimens obtained 1 to 6 hours and at least 24 hours after the episode may be useful in demonstrating a transient increase in concentrations. In the case of hereditary alpha tryptasemia, people with this trait have inherited extra copies of the alpha tryptase gene (TPSAB1), and this leads to increased levels of trypase protein detected in the blood, whether a reaction is happening or not. In cases such as these, a person may only find out because a relative was more severely affected with the syndrome. Several features that may be shared among those who have hereditary alpha tryptasemia syndrome are multiple symptoms affecting a variety of systems including (but not limited to) these: Because some people who carry the extra alpha tryptase gene copies exhibit few if any of these symptoms, we are working to determine just how common each is in people who have hereditary alpha tryptasemia.
