A functional screen of neurodevelopmental disorder risk variants identified 38 regulatory variants that may contribute to disease risk.

What it means

This study used a high-throughput functional screen to test many genetic variants previously linked to neurodevelopmental disorders (such as autism and schizophrenia) and identified 38 variants that alter regulatory activity—meaning they likely change how genes are expressed rather than the protein sequence itself. These 38 regulatory variants may represent concrete mechanisms through which risk-associated DNA changes contribute to disease.

Accuracy & sourcesGrounded

The claim is drawn directly from a bioRxiv preprint (primary research paper), so it accurately reports the authors' own findings. As a preprint, it has not yet undergone formal peer review, but the functional screen methodology is well-established and the results are internally consistent.
