Paper Talk · Apr 12, 2026 · 23m

This research describes a large-scale functional study designed to pinpoint the causal genetic variants behind complex human diseases and traits. By utilizing massively parallel reporter assays (MPRA), the authors tested over 200,000 fine-mapped variants across five different cell types to measure their direct impact on gene regulation. They successfully identified 13,121 trait-associated regulatory variants (TARVs), demonstrating that combining experimental data with genomic annotations significantly improves the accuracy of identifying disease-linked alleles. The study further employed…
