Alternative splicing events in SCN1A gene can lead to non-productive mRNA transcripts which in turn can lead to aberrant protein expression, and therapeutic agents which can target the alternative splicing events in SCN1A gene can modulate the expression level of functional proteins in Dravet Syndrome patients and/or inhibit aberrant protein expression. Such therapeutic agents can be used to treat a condition caused by SCN1A, SCN8A or SCN5A protein deficiency.

Aspects of the disclosure relate to complexes comprising a muscle-targeting agent covalently linked to a molecular payload. In some embodiments, the muscle-targeting agent specifically binds to an internalizing cell surface receptor on muscle cells. In some embodiments, the molecular payload promotes the expression or activity of a functional dystrophin protein. In some embodiments, the molecular payload is an oligonucleotide, such as an antisense oligonucleotide, e.g., an oligonucleotide that causes exon skipping in a mRNA expressed from a mutant DMD allele.

The invention relates to neurodegenerative disorders, and in particular to novel oligonucleotides for treating such conditions, for example Alzheimer's disease. The invention provides novel antisense oligonucleotides, and compositions comprising such oligos, and therapies and methods for treating neurodegenerative disorders. The invention includes genome editing techniques for achieving similar results as using the novel antisense oligonucleotides.

The present specification provides a drug that causes highly-efficient skipping of exon 50 in the human dystrophin gene. The present specification provides an antisense oligomer which induces skipping of exon 50 in the human dystrophin gene.

The present specification provides a drug that causes highly-efficient skipping of exon 50 in the human dystrophin gene. The present specification provides an antisense oligomer which induces skipping of exon 50 in the human dystrophin gene.

Antisense molecules capable of binding to a selected target site in the human dystrophin gene to induce exon 53 skipping are described.

The disclosure provides methods, base editors, vectors encoding base editors and cognate gRNAs, and compositions and kits comprise said components, for installing nucleobase edits to the SMN2 locus to increase the activity and/or amount and/or stability of SMN2 protein in a cell, thereby treating Spinal Muscular Atrophy. In certain aspect, the disclosure provides compositions and methods to edit C840T of exon 7 of the SMN2 gene, or installing another one or more nucleobase edits which have the effect of removing or inactivating a degron, such as the C-terminal portion of the region encoded by exon 6 or the 4-amino acid region encoded by exon 8 (i.e., the EMLA (SEQ ID NO: 466)-tail) so as to remove or limit their degron activity to reduce, mitigate, or eliminate the intracellular degradation of the SMN2 protein.

The present invention relates to antisense oligonucleotides that are complimentary to SOD1, leading to decreased expression of SOD1. Reduced expression of SOD1 is beneficial in medical disorders such as Amyotrophic Lateral Sclerosis.

Provided are peptide nucleic acid derivatives targeting a 3′ splice site of the human tyrosinase pre-mRNA. The peptide nucleic acid derivatives potently induce a splice variant of the human tyrosinase mRNA in cells, and are useful to safely treat dermatological indications or conditions involving the human tyrosinase protein upon topical administration.

The present invention is directed to a method for inducing skipping of exon 24 of the cystic fibrosis transmembrane conductance regulator (CFTR) pre-mRNA. Further, treating cystic fibrosis (CF) using a splicing modulator, such as an antisense oligonucleotide, capable of inducing the skipping of exon 24 of the cystic fibrosis transmembrane conductance regulator (CFTR) pre-mRNA. Also provided are a composition and a kit comprising the splicing modulator.
