Dystrophin pre-mRNA Exon 50 (DMD Exon 50)

Target
DMD Exon 50
Molecular classification
RNA, Pre-mRNA, Exon, Splice variant
01

Overview

Dystrophin pre-mRNA exon 50 is a critical exon within the pre-mRNA transcript of the DMD gene. Mutations or deletions affecting this exon often disrupt the reading frame, leading to Duchenne muscular dystrophy. Therapeutic strategies, such as exon skipping using antisense oligonucleotides, aim to restore the reading frame and produce a truncated but partially functional dystrophin protein.

02

Mechanism of action

Antisense oligonucleotides (AOs) induce exon skipping during pre-mRNA splicing, restoring the reading frame and allowing for the production of a truncated, but partially functional, dystrophin protein.
