Glycogen storage disease type III
Summary
Glycogen storage disease type III is one of the genetic disorders affecting how the body stores and uses glycogen. People with glycogen storage disease type III have a deficiency of the glycogen debrancher enzyme (α-1,6-glucosidase), one of the enzymes that help to break down glycogen. The symptoms of glycogen storage disease type III generally appear during childhood and include generalized muscle weakness, hepatosplenomegaly, fasting hypoglycemia, and ketosis.
