Gene linked to eosinophilic esophagitis plays key role in inflammation
Pediatrics researchers have identified the first major gene location responsible for a severe, often painful type of food allergy called eosinophilic esophagitis (EoE). In this disease, which may cause weight loss, vomiting, heartburn and swallowing difficulties, a patient may be unable to eat a wide variety of foods.
After performing a genome-wide association study, the study team found EoE was linked to a region of chromosome 5 that includes two genes. The likely culprit is the gene TSLP, which has higher activity levels in children with EoE compared to healthy subjects. In addition, TSLP has been previously linked to allergic inflammatory diseases, such as asthma and the skin inflammation, atopic dermatitis. Read more...
