Materials and methods for treatment of Duchenne Muscular Dystrophy
The present application provides materials and methods for treating a patient with Duchenne Muscular Dystrophy (DMD) both ex vivo and in vivo. In addition, the present application provides materials and methods for editing a dystrophin gene in a cell by genome editing.
1. A single-molecule guide RNA (sgRNA) comprising in the 5′ to 3′ direction, a spacer sequence, a minimum CRISPR repeat sequence and a tracrRNA sequence, wherein the spacer sequence consists of an RNA sequence encoded by SEQ ID NO: 1410444, and wherein the sgRNA is capable of removing an AG sequence upstream of Exon 51 in the DMD gene when administered to a cell with a Cas9 protein or a nucleic acid encoding a Cas9 protein.
2. The sgRNA of claim 1 , wherein the sgRNA comprises an RNA modification.
3. The sgRNA of claim 1 , wherein the sgRNA is complexed with a Cas9 protein.
