Area of Science:

Neurology
Genetics
Biochemistry

Background:

Duchenne and Becker muscular dystrophies are common genetic disorders.
Recent research has significantly improved understanding of their etiology.

Purpose of the Study:

To review current knowledge on the genetics, biochemistry, and pathophysiology of Duchenne muscular dystrophy.
To provide an overview of molecular diagnostic tools and their applications.

Main Methods:

Literature review of genetic and biochemical studies.
Analysis of diagnostic tool development and application.

Main Results:

Established understanding of the genetic and biochemical basis of Duchenne and Becker muscular dystrophies.
Development of gene- and protein-based molecular diagnostic tools.
Dystrophinopathies exhibit a wide spectrum of neuromuscular symptoms, not limited by sex or weakness location.

Conclusions:

Molecular diagnostics enable precise diagnosis for patients and families.
Clinical presentation of dystrophinopathies is diverse, requiring broad diagnostic consideration.
