What is Muscular Dystrophy

Muscular dystrophy (MD) encompasses a diverse group of inherited disorders characterized by progressive muscle weakness and degeneration. The condition arises from genetic mutations that impair the production or function of proteins vital for muscle fiber stability—most notably dystrophin and related proteins. This deficiency compromises muscle cell integrity, making fibers more susceptible to damage and initiating cycles of muscle cell death and regeneration. Over time, these cycles lead to fibrosis and fatty replacement of muscle tissue. MD includes several subtypes, such as Duchenne, Becker, limb-girdle, facioscapulohumeral, and myotonic dystrophies, each differing in genetic cause, age of onset, and clinical severity. Clinically, MD presents with progressive muscle weakness, loss of mobility, and, in some forms, cardiac and respiratory complications. The diagnostic approach integrates clinical assessment, elevated serum creatine kinase (CK) levels, electromyography, muscle imaging, and, increasingly, genetic testing to identify causative mutations. Muscle biopsy may support diagnosis in select cases. Treatment is primarily supportive and aimed at slowing disease progression, preserving function, and managing complications. Pharmacological options include corticosteroids (deflazacort, prednisolone), exon-skipping therapies (eteplirsen, golodirsen, viltolarsen, casimersen), gene therapy (delandistrogene moxeparvovec), and other agents such as vamorolone and givinostat. Multidisciplinary care remains essential for optimizing quality of life.

Targets for Muscular Dystrophy

Targets in Clinical or Later Phases of Development

Target Name Gene Symbol
Calpain (nonspecified subtype)
cathepsin B CTSB
cathepsin L CTSL
AMP-activated protein kinase (AMPK)
insulin INS
phosphodiesterase 5A PDE5A
Voltage-Gated Calcium Channel alpha-2/delta (nonspecified subtype)
glyceraldehyde-3-phosphate dehydrogenase GAPDH
Skeletal muscle troponin
troponin I2, fast skeletal type TNNI2

Muscular dystrophy is characterized by progressive muscle degeneration and weakness, driven by disruptions in several molecular pathways. Key therapeutic targets include proteolytic enzymes such as calpain 2 (CAPN2), cathepsin B (CTSB), and cathepsin L (CTSL), which are upregulated in dystrophic muscle and contribute to the breakdown of structural proteins following membrane instability. Additional targets, such as NADPH oxidase 3 (NOX3), drive oxidative stress by generating reactive oxygen species, exacerbating muscle fiber injury and inflammation. Proteins involved in extracellular matrix (ECM) stability, including laminin subunit alpha 1 (LAMA1) and latent transforming growth factor beta binding protein 4 (LTBP4), regulate fibrosis and maintain the structural integrity of muscle tissue. Finally, contractile apparatus components like troponin I2 (TNNI2) and troponin T3 (TNNT3) reflect ongoing muscle damage and impaired contractility in muscular dystrophy.
