Glycogen storage diseases

Glycogen storage diseases: Introduction

Glycogen storage diseases are a group of inherited genetic diseases. Glycogen storage diseases are caused by a defect in a gene that is inherited from both parents and causes the excessive buildup of glycogen in the tissues.

Glycogen is the form of glucose that is stored in the body until it is needed. Glucose is a simple sugar that is necessary for the body's production of energy. Glycogen is stored in the liver and muscles of the body.

In glycogen storage diseases, excessive glycogen build-up in the muscles and/or liver, resulting in symptoms, such as low blood sugar, muscle cramps, slow growth and enlarged liver. Symptoms and complications vary depending on the specific type of glycogen storage disease.

There are eight types of glycogen storage diseases, designated as type I - type VIII. Glycogen storage diseases type I, III, IV and VI affect the liver. Symptoms can include enlarged liver, low blood sugar and cirrhosis of the liver.

Glycogen storage diseases type V and VII affect the muscles. Symptoms can include muscle cramps and fatigue with exercise.

Symptoms of glycogen storage disease type VIII can include muscle weakness, anemia, and high levels of uric acid.

Glycogen storage disease type II can affect both the liver and heart. Symptoms can include enlarged heart and enlarged liver. In severe cases heart failure may occur in infanthood. For more details on complications and symptoms, refer to symptoms of glycogen storage diseases.

Making a diagnosis of a glycogen storage disease begins with taking a thorough medical and family history, including symptoms. A physical examination is also performed.

Testing for glycogen storage disease includes a biopsy of the affected organs, blood and urine tests and MRI imaging test. A fasting blood glucose test is done to determine if low blood sugar is present. Liver function tests can help to evaluate the functioning of the liver. A complete blood count (CBC) and uric acid tests can determine of anemia and/or high levels of uric acid are present in the blood. Other tests are performed to determine overall heath.

It is possible that a diagnosis of glycogen storage disease can be missed or delayed because symptoms vary between individuals and can be similar to symptom of other diseases, conditions or disorders. For more information on misdiagnosis, refer to misdiagnosis of glycogen storage diseases.

There is no cure for or way to prevent glycogen storage diseases, but they can be treated to minimize symptoms and control the disease. Treatment varies depending on the specific type of glycogen storage disease but may include dietary adjustments, medications and lifestyle changes. In certain severe cases, a liver transplant may be necessary. For more information on treatment, refer to treatment of glycogen storage diseases. ...more »
