Aspects of the disclosure provide nucleic acids for reducing expression of a target RNA. In some aspects, the disclosure provides nucleic acid modifications and base-pairing configurations useful in the design of nucleic acids for RNA interference.

Provided are antisense molecules capable of binding to a selected target site in the human dystrophin gene to induce exon skipping, and methods of use thereof to treat muscular dystrophy.

Provided herein are compositions for gene modification or editing and methods of using same to treat or prevent certain conditions. Specific compositions and methods capable of safely and effectively editing gene targets expressed in the liver to durably lower LDL-C thereby treating a leading cause of cardiovascular disease are disclosed.

The current invention provides an improved oligonucleotide and its use for treating, ameliorating, preventing and/or delaying DMD or BMD.

The present invention relates to compounds, compositions, and methods for the study, diagnosis, and treatment of traits, diseases and conditions that respond to the modulation of gene expression and/or activity, and/or modulate a gene expression pathway. Specifically, the invention relates to double-stranded nucleic acid molecules including small nucleic acid molecules, such as short interfering nucleic acid (siNA) molecules that are capable of mediating or that mediate RNA interference (RNAi) against target gene expression.

The current invention provides an improved oligonucleotide and its use for treating, ameliorating, preventing and/or delaying DMD or BMD.

The invention relates to RNAi agents, e.g., double-stranded RNAi agents, targeting the Serpina1 gene, and methods of using such RNAi agents to inhibit expression of Serpina1 and methods of treating subjects having a Serpina1 associated disease, such as a liver disorder.

Described are RNAi agents, e.g., double stranded RNAi agents, for inhibiting patatin-like phospholipase domain-containing protein 3 (PNPLA3) gene expression. Also disclosed are pharmaceutical compositions that include PNPLA3 RNAi agents and methods of use thereof. The PNPLA3 RNAi agents disclosed herein may be conjugated to targeting ligands to facilitate the delivery to cells, including to hepatocytes. Delivery of the PNPLA3 RNAi agents in vivo provides for inhibition of PNPLA3 gene expression. The RNAi agents can be used in methods of treatment of PNPLA3-related diseases and disorders, including non-alcoholic fatty liver disease (NAFLD), nonalcoholic steatohepatitis (NASH), hepatic fibrosis, and alcoholic or non-alcoholic liver diseases, including cirrhosis.
