Key Points about Becker muscular dystrophy

• Definition: Becker muscular dystrophy is an X-linked recessive neuromuscular disorder characterised by progressive muscle weakness due to mutations in the dystrophin gene.
• Causes:
  • Mutation in the dystrophin gene located on the X chromosome.
  • Milder form of muscular dystrophy compared to Duchenne muscular dystrophy due to partially functional dystrophin.
• Symptoms:
  • Progressive muscle weakness, particularly in the lower limbs.
  • Calf hypertrophy.
  • Difficulty with activities such as walking, running, and climbing stairs.
• Investigations:
  • Genetic testing for dystrophin gene mutations.
  • Muscle biopsy showing reduced or abnormal dystrophin levels.
  • Blood tests showing elevated creatine kinase (CK) levels.
• Management:
  • Physical therapy to maintain mobility and prevent contractures.
  • Corticosteroids may help slow disease progression.
  • Cardiac monitoring and management due to risk of cardiomyopathy.
• Complications:
  • Progressive disability and loss of ambulation.
  • Cardiomyopathy, which may lead to heart failure.
  • Respiratory failure in advanced stages.
