What is Becker muscular dystrophy

Becker muscular dystrophy (BMD) is a genetic disorder that primarily affects the muscles. It is a milder form of muscular dystrophy compared to Duchenne muscular dystrophy (DMD), but still leads to progressive muscle weakness and wasting over time.

BMD is caused by mutations in the dystrophin gene, which is responsible for producing a protein called dystrophin. This protein plays a crucial role in maintaining the structure and function of muscle fibers. In individuals with BMD, the dystrophin protein is either absent or produced in insufficient amounts, leading to muscle damage and weakness.

The symptoms of BMD typically appear in adolescence or early adulthood and may include difficulty walking, muscle cramps, muscle stiffness, and fatigue. Unlike DMD, individuals with BMD often retain the ability to walk into their 30s or beyond.

Treatment for BMD focuses on managing symptoms and improving quality of life. This may involve physical therapy, assistive devices, medications to manage muscle symptoms, and regular monitoring of heart and lung function.

Early diagnosis and intervention can help individuals with BMD lead fulfilling lives by managing symptoms and preventing complications. It is important for individuals with suspected BMD to consult with healthcare professionals for proper evaluation and guidance.
