(C;C) 5 McArdle disease (also known as glycogen storage disease type V)

This is a genotype with recommended actions if clinically confirmed. In brief:

  • Annual routine physical examination and review of diet.
  • Avoid repetitive episodes of muscle damage that may lead to rhabdomyolysis and fixed weakness.
  • Be aware risk for acute muscle damage from certain general anesthetics (usually muscle relaxants and inhaled anesthetics.
  • Statin-induced myopathy risk may be increased 12-20 fold for all carriers of a PYGM pathogenic mutation.
