Association of filaggrin variants with asthma and rhinitis: Is eczema or allergic sensitization status an effect modifier?


Background: Associations of variants of the filaggrin gene, i.e. FLG with asthma and rhinitis have been shown to be modulated by eczema status. However, it is unknown whether allergic sensitization status modifies this association. The aim of this study was to determine whether FLG variants need eczema and/or allergic sensitization as a necessary component to execute adverse effects on coexisting and subsequent asthma and rhinitis.
