IL10 and food allergy: Genetic studies have suggested that multitudes of genes could be involved in the development of allergic disease, including genes associated with vitamin D metabolism, and skin and gut barrier integrity.62 Specifically, the vitamin D response element has been identified in several genes directly relevant to food allergy pathogenesis, including those encoding for cytokines TNF‐α, IFN‐γ, IL‐10, and the antigen receptor proteins HLA‐DRB1 and HLA‐DQA1.
