Immunology of the Ancestral Differences in Eosinophilic Esophagitis

Eosinophilic Esophagitis (EoE) is an allergen driven disease characterized by eosinophilic inflammation in the esophagus1. Like other atopic disorders such as atopic dermatitis (AD), food allergy (FA), allergic rhinitis (AR), and asthma, EoE has complex etiology with genetic predisposition and environmental factors playing a major role in disease development2. The genetic predisposition has been suggested as an important factor by familial and twin studies. Additionally, numerous genetic risk loci have been now described linked to EoE risk confirming that inheritability is associated with genetic predisposition3.
