Kind: research · Impact: medium

## In brief

- CRISPR activation directed at enhancers of the autism risk genes CHD8 and SCN2A selectively increased their expression.
- The approach reversed mutant phenotypes in both patient-derived and gene-edited neuron and organoid models.
- The study reports results in organoid models; the sources do not describe effects in animals or humans.

## Why it matters

It shows that boosting expression of haploinsufficient autism risk genes through their enhancers can reverse disease-related cellular phenotypes in human models, a possible route for future therapeutic research.
