Von Gierke Disease (GSD1)

Your GSD1 coordinator is
Jason McMillan


Children with GSD1 are unable to release glucose from liver glycogen. If untreated this results in prolonged periods when their blood sugar level is too low. They become unwell in early childhood with sweating, irritability, poor growth and muscle weakness. Their livers become enlarged because of excessive accumulation of glycogen that cannot be broken down normally. In addition to these problems, children with GSD1 can develop frequent mouth ulcers and are at increased risk of infection.
