Becker muscular dystrophy is a genetic disorder that primarily affects males and is characterized by progressive muscle weakness and degeneration. 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. The condition is a milder form of Duchenne muscular dystrophy and progresses more slowly. Individuals with Becker muscular dystrophy often retain some muscle function into adulthood, but they may eventually require mobility aids. Early diagnosis and supportive therapies can help manage symptoms and improve quality of life.
