Homology-dependent repair (HDR) knock-in of CBS gene in rabbits using CRISPR/Cas9 gene editing. a CRISPR/Cas9-targeting sites on the rabbit CBS gene. The red letters in the sgRNA sequences are specific for exon 8, and the green letters indicate the protospacer adjacent motif (PAM). b Donor template sequences with silent mutations (green letters) and G307S (red letters)
