Genetic risk factors for EoE include polymorphisms in thymic stromal lymphopoetin (TSLP), its receptor (TSLPR), the tissue specific gene calpain 14, the trafficking protein ANKRD21 as well as genes associated with atopic and autoimmune diseases, specifically c11orf30 and STAT6 [17,18]. This evidence concerns the gene TSLP and eosinophilic esophagitis.
