| abstract |
Antisense polynucleotides and their use in pharmaceutical compositions to induce exon skipping in targeted exons of the gamma sarcoglycan gene are provided, along with methods of preventing or treating dystrophic diseases such as Limb-Girdle Muscular Dystrophy. One aspect the disclosure provides an isolated antisense polynucleotide wherein the polynucleotide specifically hybridizes to an exon target region of a gamma sarcoglycan RNA, wherein the exon is selected from the group consisting of exon 4 (SEQ ID NO:1), exon 5 (SEQ ID NO: 2), exon 6 (SEQ ID NO: 3), exon 7 (SEQ ID NO: 4) and a combination thereof. In some embodiments, the antisense polynucleotide cannot form an RNase H substrate, and in further embodiments the antisense polynucleotide comprises a modified polynucleotide backbone. |
