Understanding McArdle Disease: Causes, Symptoms, and Diagnosis
McArdle disease, also known as glycogen storage disease type V, is a rare genetic disorder that affects the way your body uses glycogen - a type of sugar that the body uses for energy. This condition is caused by a deficiency of the enzyme called myophosphorylase, which is necessary for breaking down glycogen in muscle cells.
McArdle disease is inherited in an autosomal recessive pattern, meaning that a person must inherit two copies of the mutated gene - one from each parent - to develop the condition. If only one parent carries the mutated gene, the child will be a carrier but will not have the disease.
Symptoms of McArdle Disease
The most common symptom of McArdle disease is muscle weakness, especially during exercise. Other symptoms may include muscle cramps, pain, and stiffness, as well as fatigue and a limited ability to perform physical activities. Some people with McArdle disease may also experience rhabdomyolysis, a condition in which damaged muscle fibers release their contents into the bloodstream.
Diagnosis of McArdle Disease
Diagnosis of McArdle disease is usually made through a combination of medical history, physical examination, and genetic testing. Doctors may also perform a muscle biopsy to confirm the diagnosis. During a muscle biopsy, a small sample of muscle tissue is removed and examined under a microscope to look for the absence of myophosphorylase.
Conclusion
- McArdle disease is a rare genetic disorder that affects the way your body uses glycogen.
- Symptoms include muscle weakness, cramps, pain, stiffness, fatigue, and a limited ability to perform physical activities.
- Diagnosis is usually made through a combination of medical history, physical examination, and genetic testing.
If you or someone you know is experiencing symptoms of McArdle disease, it is important to talk to a doctor as soon as possible. While there is no cure for the condition, there are treatments available to manage symptoms and improve quality of life.

McArdle disease, also known as glycogen storage disease type V, is a rare genetic disorder that affects the way the body uses and stores glycogen, a form of energy stored in the muscles. This condition is caused by a deficiency in the enzyme myophosphorylase, which is responsible for breaking down glycogen into glucose in muscle tissue. As a re...
