RNA, pre-mRNA, Splice target
01

Overview

Dystrophin pre-mRNA containing exon 53 is a crucial molecular target in genetic therapies for Duchenne muscular dystrophy. By inducing skipping of this specific exon during mRNA processing, it becomes possible to restore partial function even when disease-causing mutations disrupt normal translation downstream from this region. This approach underpins several current RNA-based therapeutics aimed at treating subsets of patients with amenable genotypes.
