Genetic biomarker may predict severity of food allergy
Researchers have discovered a genetic biomarker that could help predict the severity of food allergy reactions.
The biomarker, called α-tryptase, is an enzyme isoform encoded by the TPSAB1 gene.
Presence of α-tryptase is associated with an increased prevalence of anaphylaxis or severe reactions to food.
A commercially available test can easily determine if a patient has α-tryptase, allowing for better understanding of their risk and potential treatment strategies.

Researchers have identified a genetic biomarker that could potentially help predict the severity of food allergy reactions. The biomarker, known as α-tryptase, is an enzyme isoform encoded by the TPSAB1 gene. Its presence has been found to correlate with an increased risk of anaphylaxis or severe reactions to food. By using a commercially available test to detect α-tryptase, physicians can better understand a patient’s risk and potentially develop targeted treatments. However, further research is needed to validate these findings and gain a better understanding of α-tryptase’s role in food allergies.
