Two-stage Genome-wide Methylation Profiling in Childhood-onset Crohnʼs Disease Implicates Epigenetic Alterations at the VMP1/MIR21 and HLA Loci

Abstract

We demonstrate highly significant and replicable differences in DNA methylation in CD, defining the disease-associated epigenome. The data strongly implicate known GWAS loci, with compelling evidence implicating MIR21 and the HLA region.
