Abstract

To provide nucleic acid-polypeptide compositions and methods for inducing exon skipping.SOLUTION: Disclosed herein are molecules and pharmaceutical compositions that induce an insertion, deletion, duplication, or alteration in an incorrectly spliced mRNA transcript to induce exon skipping or exon inclusion. Also described herein are methods for treating a disease or disorder that comprises a molecule or a pharmaceutical composition that induces an insertion, deletion, duplication, or alteration in an incorrectly spliced mRNA transcript to induce exon skipping or exon inclusion.SELECTED DRAWING: Figure 3
