Researchers Mapped Human Gene Regulation Across 21 Tissues
A new single-nucleus atlas links over one million regulatory elements to gene expression in human adult tissues.
Updated on Sept. 27, 2026 in Life Sciences
Researchers have published a comprehensive multi-omic atlas of gene regulation, detailing 459,856 profiles across 21 adult human tissues. This research-stage dataset provides a framework for interpreting how non-coding DNA variants influence complex human traits.
Why it matters
Understanding the regulatory landscape of the human genome is essential for mapping the functional consequences of genetic variation. This atlas provides a foundational resource for linking high-effect variants to specific cell types and gene expression patterns.
The dataset maps 1,085,062 candidate cis-regulatory elements, including 161,270 previously uncharacterized sequences. Researchers established 871,177 associations between these elements and gene expression using paired measurements from 160,688 nuclei.
The details
The team employed single-nucleus multi-omic profiling, a method that simultaneously analyzes the transcriptome—the complete set of RNA transcripts—and chromatin accessibility—the degree to which DNA is available for transcription—within individual cells. By training sequence-to-function models, researchers predicted how chromatin-accessibility changes affect fine-mapped variants. This enabled the identification of 18,133 high-effect genetic variants that likely drive gene regulation across 313 distinct cell subclusters.

The Tech Race
The study follows the precedent set by the ENCODE project by expanding regulatory mapping into single-cell tissue resolution. This atlas significantly accelerates the shift toward high-resolution functional genomics compared to earlier, bulk-tissue sequencing efforts.
This resource is currently a research-stage tool intended for use by geneticists and computational biologists to refine the interpretation of genomic data. Clinicians and researchers can use these associations to better understand the mechanisms behind complex genetic traits and disease susceptibility.
The takeaway
The atlas provides a definitive map for researchers to cross-reference genetic variants against active regulatory elements. Future efforts will focus on validating the functional impact of the 1,120 broadly active variants identified in the dataset.
