CEP290 and Leber congenital amaurosis 10: Leber congenital amaurosis 10 (LCA10) is a severe rare genetic eye disease caused by mutations in the CEP290 gene, and SaCas9 was delivered in conjunction with dual gRNAs into a human CEP290 IVS26 knock-in mouse model by a single adeno-associated virus (AAV) to remove the aberrant splice donor generated by the IVS26 mutation of the CEP290 gene (169).
