Abstract

Abstract: CRISPR (clustered regularly interspaced short palindromic repeats)/Cas gene editing is a revolutionary technology that can enable the correction of genetic mutations , providing great promise as a therapeutic intervention for inherited diseases. Adeno-associated viral (AAV) vectors are a potential vehicle for delivering CRISPR/Cas. However, they are restricted by their limited packaging capacity. Identifying smaller Cas orthologs that can be packaged, along with the required guide RNA elements, into a single AAV would be an important optimization for CRISPR/- Cas gene editing. Expanding the options of Cas proteins that can be delivered by a single AAV not only increases translational application but also expands the genetic sites that can be targeted for editing. This review considers the benefits and current scope of small Cas protein orthologs that are suitable for gene editing approaches using single AAV vector delivery.
