J Allergy Clin Immunol Glob. 2023 Mar 21;2(2):100095. doi: 10.1016/j.jacig.2023.100095. eCollection 2023 May.

Abstract

To our knowledge, we present the first case report of allergic reaction from oyster mushroom ingestion, which was confirmed by an oral food challenge test. Trehalose phosphorylase was identified as a novel potential allergen by IgE immunoblotting and mass spectrometry.

Keywords: Mushroom allergy; allergen; anaphylaxis; oyster mushroom; trehalose phosphorylase.
