Dystrophin pre-mRNA (exon 51)

Molecular classification
Precursor mRNA, RNA
01

Overview

Dystrophin pre-mRNA containing exon 51 is a critical molecular target for therapies aiming to treat Duchenne muscular dystrophy caused by out-of-frame mutations involving this region. By inducing targeted skipping of this exon during RNA processing using antisense technologies, it is possible to restore production of a shorter but still functional form of the essential structural protein dystrophin—offering clinical benefit by converting severe disease phenotypes toward milder ones seen in Becker muscular dystrophy patients.
