Common variants at 5q22 associate with pediatric eosinophilic esophagitis

Hakon Hakonarson and colleagues identify variants near TSLP at 5q22 associated with pediatric eosinophilic esophagitis. They further show that TSLP is overexpressed in esophageal biopsies of cases compared to controls and that the risk variants are associated with elevated TSLP expression.
