Glycogen storage disease type 0 liver provides a steady source of glucose from glycogen breakdown (or glycogenolysis). With prolonged fasting, glucose is generated in the liver from noncarbohydrate precursors through gluconeogenesis. Such precursors include alanine (derived from the breakdown of proteins in skeletal muscle) and glycerol (derived from the breakdown of triacylglycerols in fat cells). In patients with glycogen-storage disease type 0, fasting hypoglycemia occurs within a few hours after a meal because of the limited stores of hepatic glycogen and inadequate gluconeogenesis to maintain normoglycemia. Feeding characteristically results in postprandial hyperglycemia and glucosuria, in addition to increased blood lactate levels, because glycogen synthesis 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
