CP and allergic disease: This BN-virus peak group also contained the following genes previously implicated in asthma/allergy: high affinity immunoglobulin E receptors Fcεr1a and Fcεr1b (also known as Ms4a2), which are key genes in allergic responses [40]–[42]; Tslp which encodes a pro-inflammatory cytokine-like factor with polymorphisms linked to asthma susceptibility [43]; and Cp, which encodes an antioxidant and free radical scavenger produced by the airway under stressful conditions such as endotoxin administration (Figure S10) [44].
