Washington: A gene that could be responsiblefor a severe and often painful type of food allergy calledeosinophilic esophagitis (EoE) has been discovered by Americanscientists.
A person suffering from EoE, which may cause weightloss, vomiting, heartburn and swallowing difficulties, may notbe able to eat a wide variety of foods, the study said. The hallmark of EoE is swelling and inflammation in theesophagus, accompanied by high levels of immune cells calledeosinophils. It can affect people of any age, but is morecommon among young men who have a history of other allergicdiseases such as asthma and eczema. In the current study, the researchers performed agenome-wide analysis on 181 samples from the Cincinnaticenter, compared to nearly 2,000 healthy controls from TheChildren`s Hospital of Philadelphia (CHOP).
