👉 Glycogenosis is a type of metabolic disorder characterized by a buildup of glycogen in the liver, kidneys, and other tissues. It is caused by a deficiency or malfunction in the enzyme that breaks down glycogen into glucose. This can lead to high blood sugar levels and complications such as diabetes, heart disease, and kidney failure. There are several types of glycogenosis, including glycogen storage diseases (GSD), glycogenetic disorders, and glycogenopathies.
