Researchers at the Icahn School of Medicine at Mount Sinai have identified novel genes associated with the severity of peanut allergy, as well as ways in which these genes interact with other genes during allergic reactions.

The findings, published December 12 in the Journal of Allergy and Clinical Immunology, could lead to better treatments for peanut allergy.

Peanut allergy varies widely in severity and is the leading cause of fatal food-related anaphylaxis. The tests used to determine the existence of a peanut allergy don’t offer any clues as to whether an individual ingesting a peanut could experience a minor rash, major swelling, or life-threatening issues such as difficulty breathing or cardiovascular complications.
