Briefings

A 2026 Nature study analyzed 10 million immune cells from 1,108 individuals to link disease-associated changes in genome accessibility directly to gene expression. This approach reveals that many disease-linked genetic alterations do not affect the genes themselves but instead alter how strongly they are expressed, a finding that challenges previous models of disease mechanisms.

Key points

• The study analyzed 10 million immune cells from 1,108 individuals to link disease-associated changes in genome accessibility to gene expression.
• Most disease-associated genetic alterations do not affect the genes themselves but instead change how strongly they are expressed.

Context

This research provides a new method for understanding disease mechanisms by simultaneously analyzing genome accessibility and gene expression in large immune cell cohorts, revealing that accessibility changes drive disease risk independent of gene sequence alterations.

Limitations

Data covers only immune cells from 1,108 people, limiting generalizability to other cell types or populations. Results are observational and do not establish causality, and no clinical outcomes or treatment effects are reported.
