CAPN14 and eosinophilic esophagitis: The reporter constructs assay revealed that the rs76562819 genetic variant was sufficient to produce genotype-dependent promoter activity highly similar to what is observed between risk and non–risk haplotypes in EoE patients, so it can be concluded that the rs76562819 EoE risk allele results in the decrease in IL13–induced CAPN14 expression in EoE patients.
