Children were further studied regarding symptoms of allergy (rhinitis, asthma, atopic dermatitis) according to international guidelines, and skin prick testing with a panel of aeroallergen extracts was performed before sera were analyzed in an investigator‐blinded manner for IgE specific to more than 160 micro‐arrayed allergen molecules using ImmunoCAP ISAC technology. This evidence concerns the gene IGHE and rhinitis.
