Glycogen Storage Disease IV
What's glycogen storage disease IV?
Glycogen storage disease IV (GSD IV) is a genetic condition where your body can not properly build a complex sugar called glycogen. Typically, our bodies break down the food we eat into energy. Some of this energy gets used right away, while the rest gets stored as glycogen in our muscles and liver for later use. People with GSD IV have a genetic change which makes their glycogen an abnormal shape with many long branches. The body does not recognize this as normal glycogen, so the immune system attacks the abnormal glycogen, causing scars in the liver and muscles where the glycogen is stored. This causes the signs and symptoms of glycogen storage disease IV.
