Question

Most patients with moderate to severe glycogen storage disease experience some growth retardation. What feature of the glycogen storage diseases would account for this?

Answer 1

YES

The defect leading to this disorder occurs on chromosome 14. GSD type IX is a more heterogeneous disorder, caused by a deficiency of phosphorylase kinase. Phosphorylase kinase deficiency is the most common glycogen storage disease, representing 25% of all patients with a glycogen storage disease.
