Bicluster of GWAS phenotypes based on eGene pleiotropy FadasonTayaza 2018 Chromatin interactions (using Hi-C) and functional (using eQTL) data were used to identify long-range regulatory associations involving >20,000 GWAS variants and their target genes (i.e. eGenes). This figure shows clusters of phenotypes that share eGenes, which implies a common underlying molecular mechanism.
