Dystrophin Expression Modulator

Molecular classification
Other
01

Overview

A dystrophin expression modulator is any molecule, drug, or genetic intervention designed to increase, restore, or regulate the production of dystrophin protein in muscle cells. Dystrophin is a critical structural protein that stabilizes muscle fibers during contraction and protects them from injury. Loss or deficiency of dystrophin leads to Duchenne muscular dystrophy (DMD), a severe X-linked neuromuscular disorder.

02

Mechanism of action

Varies depending on the specific modulator. Examples include exon skipping, microRNA inhibition, and genome editing to increase or restore functional dystrophin expression.
