CRISPR–Cas9 editing shows promise for correcting disease-causing mutations. For example, in a recent study we used CRISPR-Cas9 for sight restoration in blind rd1 mice by correcting a mutation in the Pde6b gene1. However, concerns persist regarding secondary mutations in regions not targeted by the single guide RNA (sgRNA).
