Antisense RNA therapies for muscular dystrophies.

Inherited muscular dystrophies are a heterogeneous group of diseases, caused by different types of genetic mutations. RNA therapies, and particularly antisense oligonucleotides, offer a palette of therapeutic strategies to either reduce the production of harmful proteins or to restore or increase protein expression. Consequently, they offer therapeutic promise for multiple forms of muscular dystrophies. This review outlines the different RNA therapy types considered for the treatment of Duchenne muscular dystrophy, facioscapulohumeral muscular dystrophy and myotonic dystrophy, emphasizing the strategies used to deliver these therapies to skeletal muscle with a focus on approaches that have reached the clinical trial stage.
