A growing amount of children in the Western world are afflicted with a severe peanut allergy, says a recent BBC article on the subject. Dundee University in the UK has recently made a "significant breakthrough" in understanding why more children are severly allergic to peanuts. A gene called Filaggrin is responsible for the allergy, the research shows, and a defect in Fillagrin may reduce the skin's barrier "against irritants and allergens." Because allergic conditions commonly run in families, scientists knew a genetic component was important and likely. The study, published in the Journal of Allergy and Clinical Immunology, "suggests one in five peanut allergy sufferers have a Fillagrin defect."
Hopefully in the future, this can help assuage the suffering of children and grownups with deadly peanut allergies.
