'Gene flaw' linked to peanut allergy

11th March 2011

Scientists have identified a gene defect that can triple the risk of a child developing an allergy to peanuts.

An international research team led by Dundee University discovered that the Filaggrin gene helped to make the skin a good barrier against irritants and allergens but that changes in the gene decreased the effectiveness of this barrier. That in turn allowed substances to enter the body and lead to a range of allergic conditions, including peanut allergy that affects 1-2% of children in the UK.
