OPTIMIZED STRATEGY FOR EXON SKIPPING MODIFICATIONS USING CRISPR/CAS9 WITH TRIPLE GUIDE SEQUENCES

摘要

CRISPR/Cas9-mediated genome editing holds clinical potential for treating genetic diseases, such as Duchenne muscular dystrophy (DMD), which is caused by mutations in the dystrophin gene. Here, using three promoters to drive expression of the same DMD guide RNA, a more robust and safe form of genome editing was achieved in a humanized mouse model for DMD with a deletion 13 in exon 50, and in a ΔEx50-MD Dog.
