GSD is a genetic disease characterised by missing enzymes. Inheritance is typically autosomal recessive.

GSD involves disrupted glycogen metabolism. It makes glycogen accumulate or not form properly, so the glycogen cannot be broken down into glucose or stored like normal.

Treatment can include dietary modification.
