When Our Protective Armor Shows Weakness: Genetic Defect In Skin Cells Leads To Neurodermatitis, Hay Fever And Asthma

Monday, August 4, 2008 - 11:28 in Health & Medicine

New knowledge points to the fact that a genetically induced lack of filaggrin, a key protein of the skin barrier, plays a decisive role in the origin of allergies. In a large study on more than 3000 school-children scientists found that about 8% of the German population carry variations of the filaggrin gene, which raise the risk to develop atopic dermatitis more than threefold. In addition, these genetic variations predispose to hay fever and asthma in those with atopic dermatitis.
