# Hereditary alpha tryptasemia and food allergy

## TL;DR

This paper explores the possible link between food allergy and hereditary alpha-tryptasemia, a genetic condition that may influence the severity of allergic reactions.

## Contribution

The paper introduces the novel idea that hereditary alpha-tryptasemia may be a risk factor for more severe food allergy reactions.

## Key findings

- Hereditary alpha-tryptasemia may be associated with increased severity of food allergy reactions.
- More research is needed to understand the relationship between food allergy and hereditary alpha-tryptasemia.
- Tryptase genotyping could be important in managing food allergy cases.

## Abstract

Food allergy (FA) and hereditary alpha-tryptasemia (HαT) are both relatively common conditions, but potential associations between these diagnoses have not been well-studied. Prior studies have suggested that acute rises in tryptase following food allergy reactions may not be as significant as reactions triggered by venom or drug allergy, but preliminary evidence suggests that the presence of α-tryptase and HαT is a risk factor for more severe reactions to foods. This mini review summarizes the epidemiology and diagnostic considerations of FA for patients with co-morbid HαT, potential effect of α-tryptase on food allergy reaction severity, and implications of tryptase genotyping in the management of FA. Additional research is needed to further investigate the relationship between FA and HαT.
