It is caused by an inborn error of metabolism resulting in a mutation in the GBE1 gene that causes a defect in the glycogen branching enzyme leading to accumulation of abnormal glycogen molecules particularly in cardiac and muscle cells. The severity of this disease varies on the amount of enzyme produced.
