Description
This panel was developed and is maintained by VCGS.

The glycogen storage diseases (GSDs) are a group of inherited metabolic disorders caused by deficiency of enzymes involved in the production or breakdown of glycogen. 

The GSDs can be divided into 4 categories:
1). GSDs predominantly affecting the liver and having a direct influence on blood glucose level (types I, VI, and VIII)
2). GSDs predominantly affecting muscle and having a direct influence on muscle function (types V and VII)
3). a GSD affecting liver and muscle and having a direct influence on blood glucose level and muscle function (type III)
4). GSDs affecting liver, muscle, and other tissues and having no direct effect on blood glucose or muscle function (types II and IV).
