Dystrophin pre-mRNA Exon 44 (DMD Exon 44)

Target
DMD Exon 44
Molecular classification
mRNA, Exon, Pre-mRNA splicing target
01

Overview

Dystrophin pre-mRNA exon 44 is the 44th exon in the pre-mRNA transcript of the DMD gene. It is a therapeutic target for exon skipping strategies in Duchenne muscular dystrophy (DMD). Antisense oligonucleotides (ASOs) are designed to bind to this exon, causing it to be skipped during mRNA splicing, potentially restoring the reading frame and producing a truncated but partially functional dystrophin protein.
