Becker Muscular Dystrophy (BMD) is a genetic disorder that primarily affects muscles, leading to progressive weakness and wasting. It is caused by mutations in the dystrophin gene, which is essential for maintaining muscle cell integrity. Symptoms typically appear in childhood or adolescence and may include difficulty walking, muscle cramps, and heart problems. Unlike Duchenne Muscular Dystrophy, which is more severe, BMD usually progresses more slowly, allowing individuals to maintain some muscle function into adulthood. Diagnosis often involves genetic testing, muscle biopsies, and assessments of muscle strength. Treatment focuses on managing symptoms and improving quality of life.
