Abstract
Rare diseases occur in their large majority from a genetic cause, which makes them good candidates for genetic
RNA drugs. The basic concepts, principles, mechanisms of action and chemical optimizations of synthetic
antisense oligonucleotides (ASO) and small interfering RNA (siRNA) are illustrated. These drugs act either by
leading to RNA degradation, or as steric blockers of RNA translation, microRNA antagonists, splicing modulators or
inducers of exon skipping. Chemical modifications and delivery techniques differ and are adapted to their distinct
functions. The successes, potential, and challenges of synthetic RNA drugs are illustrated for several muscular and
neuromuscular diseases: Duchenne muscular dystrophy, spinal muscular atrophy, transthyretin amyloidosis, Type 1
myotonic dystrophy, centronuclear myopathy, oculopharyngeal muscular dystrophy.
Keywords: Antisense oligonucleotide, neuromuscular disorders, rare disease, RNA drug, RNA interference, small
interfering siRNA
