Introduction Filaggrin is a major epidermal protein that has been shown to be a key player in the pathogenesis of atopic dermatitis (AD) and allergic disease. Although filaggrin is a significant genetic risk WebBackground: Filaggrin (FLG) mutations are major genetic determinants for eczema, but their role in eczema severity needs further investigation. Children with eczema are at higher risk of having asthma and rhinitis but it is not known if this risk is associated with the severity of eczema.

WebAbstract. Recent genetic findings demonstrate an important role for the epidermal protein filaggrin in the aetiology of atopic diseases, including asthma as well as eczema. Filaggrin is critical to the conversion of keratinocytes to the protein/lipid squames that compose the stratum comeum, the outermost barrier layer of the skin. Individuals with truncation mutations in the gene coding for filaggrin are strongly predisposed to a severe form of dry skin, ichthyosis vulgaris, and/or eczema. It has been shown that almost 50% of all severe cases of eczema may have at least one mutated filaggrin gene. R501X and 2284del4 are not generally found in non-Caucasian individuals, though novel mutations (3321delA and S2554X) that yield similar effects have been found in Japanese …
