Filaggrin mutations in the onset of eczema, sensitization, asthma, hay fever and the interaction with cat exposure

Abstract

FLG mutations are associated both with atopic and nonatopic eczema starting in the first year of life. FLG mutations combined with eczema in the first year of life are associated with a later development of asthma and hay fever, a clear example of the atopic march. We confirm that cat exposure enhances the effect of a FLG mutation on the development of eczema and sensitization.
