CRISPR/Cas9 DNA editing creates a double-stranded break in the target DNA, which can frequently generate random insertion or deletion of bases (indels); a new genome editing approach combining Cas9 with a cytidine deaminase is described here, which corrects point mutations more efficiently than canonical Cas9, while avoiding double-stranded breaks and indel formation.
