Glycogen storage disease type IV old. It has not been associated with cirrhosis or liver failure. Glycogen storage disease type IV Glycogen storage disease type IV, also known as Andersen’s Disease, is a form of glycogen storage disease, which is caused by an inborn error of metabolism. It is the result of a mutation in the GBE1 gene, which causes a defect in the glycogen branching enzyme. Therefore, glycogen is not made properly and abnormal glycogen molecules accumulate in cells; most severely in cardiac and muscle cells. The severity of this disease varies on the amount of enzyme produced. Glycogen Storage Disease Type IV is
Glycogen storage disease type II International Pompe Association. John Crowley became involved in the fund-raising efforts in 1998 after two of his children were diagnosed with Pompe's. He joined the company Novazyme in 1999, which was working on enzyme replacement treatment for Pompe's. Novazyme was sold to Genzyme in 2001 for over US$100 million. The 2010 film "Extraordinary Measures" is based on Crowley's search for a cure. Glycogen storage disease type II Glycogen storage disease type II, also called Pompe disease, is an autosomal recessive metabolic disorder which damages muscle and nerve cells throughout the body. It is caused by an accumulation of glycogen in
