摘要

Recently, our research team found a strong and significant association between loss-of-function (LOF) mutations in filaggrin (FLG), a gene that encodes a skin barrier protein, in European and Canadian individuals with peanut allergy (PA).1 These mutations result in a barrier defect and have been associated with atopic dermatitis, asthma, and allergic rhinitis.2 This finding represents the strongest genetic risk factor found to date for PA, a highly heritable disease,3 with an estimated odds ratio (OR) between 1.9 (Canadian) and 5.3 (English, Dutch, and Irish combined).1 Because there is no uniformly accepted definition of PA short of oral food challenge, it is worthwhile to examine whether the association between the FLG LOF mutations and PA varies with the diagnostic criteria for PA. Furthermore, the frequent coexistence of PA with other atopic conditions may mean that the association between PA and FLG LOF mutations is confounded.
