Duchenne muscular dystrophy.

Area of Science:

• Genetics and Molecular Biology
• Neurology
• Cardiology

Background:

• Duchenne muscular dystrophy (DMD) is a severe, progressive genetic disorder.
• It results from mutations in the DMD gene, leading to a lack of dystrophin protein essential for muscle integrity.
• This deficiency causes progressive muscle wasting, functional impairment, cardiomyopathy, and premature death.

Purpose of the Study:

• To summarize current understanding of DMD pathogenetic mechanisms.
• To highlight established multidisciplinary care guidelines for DMD.
• To review approved and investigational therapies for DMD.

Main Methods:

• Review of recent scientific literature on DMD.
• Analysis of established clinical care guidelines.
• Survey of current therapeutic landscape, including approved and developmental treatments.

Main Results:

• Recent studies have elucidated primary and secondary pathogenetic mechanisms of DMD.
• Multidisciplinary care guidelines for genetic diagnosis and disease management are established.
• Several therapies targeting dystrophin restoration or secondary pathology are approved, with many more in clinical development.

Conclusions:

• Significant advancements have been made in understanding DMD.
• Comprehensive care guidelines and a growing number of therapeutic options offer hope for improved patient outcomes.
• Ongoing research and clinical development are critical for addressing the unmet needs in DMD.
