Genome-wide association analysis of eosinophilic esophagitis provides insight into the tissue specificity of this allergic disease

Marc Rothenberg, John Harley and colleagues present the results of a genome-wide association study of eosinophilic esophagitis. They discover an association with variants near CAPN14 and show that CAPN14 is expressed specifically in the esophagus and is upregulated in esophageal biopsies of individuals with active disease.
