Andersen disease is one of the glycogen storage diseases and is characterized by cirrhosis and liver failure. Individuals with glycogen storage diseases are unable to break glycogen down to glucose, thus causing abnormal accumulation of glycogen in the liver or muscle. Storing excess amounts of glycogen results in muscle weakness and an enlarged liver. Individuals with glycogen storage diseases are unable to convert glycogen to glucose, so they must be fed every few hours to ensure constant glucose from ingested food sources. This disease is inherited as an autosomal recessive trait and symptoms are caused by abnormal glycogen levels.
