Glycogen storage disease (GSD) is a rare condition that changes the way the body uses and stores glycogen, a form of sugar or glucose. Glycogen is a main source of energy for the body. Glycogen is stored in the liver. When the body needs more energy, certain proteins called enzymes break down glycogen into glucose While defects in the great majority of soluble lysosomal enzymes result in lysosomal storage disorders due to a defect in the catabolic turnover of their substrates, only 10 lysosomal membrane transporters have been associated with inherited human disorders (reviewed in []). These include the long known transporters like Sialin, Cystinosin. Enzyme replacement therapy (ERT) was eventually shown to be extraordinarily effective for patients with Gaucher disease, the most prevalent metabolic storage disorder of humans. Demonstration of the benefit of ERT in this disorder led to the extension of this approach to the treatment of other lysosomal storage disorders
