What is Glycogen Storage Disease?

Glucose is a major source of energy for the body. It is stored in the form of glycogen in both the liver and muscles and later released with the help of enzymes.

Persons affected by Glycogen Storage Disease (GSD) have an inherited defect in one of the enzymes responsible for forming or releasing glycogen as it is needed by the body during activity and/or between meals.

Mainly it is liver or muscles that are involved

GSD can affect the liver, the muscles or both. Diagnosis of the GSD variant is made on the basis of an individual’s symptoms, the results of a physical examination and of biochemical tests. Increasingly DNA testing is able to confirm the diagnosis, but occasionally a muscle or liver biopsy is required to clarify the actual enzyme defect.

Now read about the list of GSD variants.
