A study proposes using topologically associated domains to identify pathogenic non-coding variants in rare disease patients.

What it means

This bioRxiv preprint describes a computational method that uses topologically associated domains (TADs) to identify non-coding DNA variants that may cause rare diseases in patients who have remained undiagnosed after standard genetic testing. By focusing on structural regions of the genome that organize gene regulation, the approach aims to find hidden pathogenic variants missed by conventional exome or genome sequencing.

Accuracy & sourcesSourced

The claim is based on a primary source (a bioRxiv preprint), which is the actual research paper rather than a news report. As a preprint, it has not yet undergone formal peer review, so the findings should be considered preliminary but are directly from the authors who conducted the study.
