FOOD allergies could be down to genetics after scientists found a new gene associated with peanut allergy.
The breakthrough provides further evidence genes play a role in the development of food allergies. It could help identify those at risk of an allergy and lead to new treatments.
It is estimated one in every 14 British children under three has at least one food allergy. Most are allergic to milk, eggs, soya and wheat in childhood but grow out of it by the time they start school.
Yet allergies to peanut and tree nut allergies persist and an estimated four out of five children with peanut allergies remain allergic to peanuts for the rest of their lives.
For reasons that are unclear rates of food allergies have risen sharply in the past 20 years.
Associate Professor Dr Denise Daley at The University of British Columbia said: “Food allergy is the result of both genetic and environmental factors, but there are surprisingly few data regarding the genetic basis of this condition.
“The discovery of this genetic link gives us a fuller picture of the causes of food allergies, and this could eventually help doctors identify children at risk.”
Why are you making commenting on The Herald only available to subscribers?
It should have been a safe space for informed debate, somewhere for readers to discuss issues around the biggest stories of the day, but all too often the below the line comments on most websites have become bogged down by off-topic discussions and abuse.
heraldscotland.com is tackling this problem by allowing only subscribers to comment.
We are doing this to improve the experience for our loyal readers and we believe it will reduce the ability of trolls and troublemakers, who occasionally find their way onto our site, to abuse our journalists and readers.
