Overview

Glycogen storage disease due to glycogen branching enzyme deficiency, progressive hepatic form, is a rare inherited metabolic disorder also known as Andersen disease or glycogen storage disease type IV (GSD IV) in its progressive liver form. This condition is caused by a deficiency of the glycogen branching enzyme (GBE), which is needed to build glycogen — the body's main way of storing sugar for energy. Without enough of this enzyme, the body produces an abnormal form of glycogen called amylopectin-like polysaccharide (polyglucosan), which accumulates in the liver and other organs. In the progressive hepatic form, the liver is the primary organ affected. Infants and young children typically develop an enlarged liver and spleen, failure to thrive, and progressive liver disease that can advance to cirrhosis (scarring of the liver) and liver failure. Symptoms usually appear in the first months of life and worsen over time. Children may also experience low muscle tone, poor growth, and general weakness. There is currently no cure for this condition. Treatment is mainly supportive and focused on managing liver disease and nutritional needs. Liver transplantation is the most significant treatment option and can be life-saving for children with progressive liver failure. After transplant, the abnormal glycogen does not accumulate in the new liver, and liver function can be restored. However, the disease may still affect other organs over time. Early diagnosis and referral to a specialized metabolic and liver center are essential for the best possible outcomes.

Inheritance

Autosomal recessive

Passed on when both parents carry the same gene change; often skips generations

Age of Onset
