FLG mutations (R501X, 2282del4, and R2447X) were identified in 16.9% of patients, and were significantly associated not only with atopic dermatitis, but also independently with skin fissures on the fingers and heels, and self-reported actinic keratosis.
FLG mutations R501X, 2282del4 and R2447X were genotyped in the Prevention and Incidence of Asthma and Mite Allergy birth cohort (n = 934) to evaluate longitudinally, for up to 8 years, their association with eczema, sensitization, asthma, hay fever and their interaction with cat exposure.
