Combined glycogenosis is a rare hereditary disease associated with impaired metabolism of muscle glycogen in muscle cells, liver and other organs. This is a serious pathology that leads to serious consequences. Treatment of combined glycogenosis requires complex medical intervention, including organ transplantation, as well as gene therapy. For this disease, patients may be offered, for example, tablet drugs, hepatoprotective agents, dietary intake and other treatment methods. However, despite all efforts, combined glycogenosis can be fatal.
