807-Multitissue Epigenomic Variation of Human Disease

Paper Talk · Apr 17, 2026 · 23m

Researchers profiled epigenomic variation across hundreds of human tissue samples to understand how noncoding genetic variants influence complex diseases. By mapping H3K27ac histone marks in the brain, heart, muscle, and lung, the study identified over 280,000 active regulatory elements and linked them to specific biological contexts like sex and tissue type. The authors introduced haQTLs to reveal how genetic differences drive changes in these regulatory regions, providing a clearer map of the "circuits" between DNA variants and target genes. This data helps explain the molecular mechanisms…
