A glycogen storage disease(GSD, also glycogenosisand dextrinosis) is a metabolic disordercaused by a deficiency of an enzymeor transport proteinaffecting glycogen synthesis, glycogen breakdown, or glucose breakdown, typically in musclesand/or livercells. [1] GSD has two classes of cause: genetic and environmental.
1 in 100,000 live births. Glycogen storage disease type I (GSD I) is an inherited disease that prevents the liver from properly breaking down stored glycogen, which is necessary to maintain adequate blood sugar levels. GSD I is divided into two main types, GSD Ia and GSD Ib, which differ in cause, presentation, and treatment.
Glycogen (black granules) in spermatozoa of a flatworm; transmission electron microscopy, scale: 0.3 μm. Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals, [2] fungi, and bacteria. [3] It is the main storage form of glucose in the human body.
Glycogen storage disease type V (GSD5, GSD-V), [ 1 ] also known as McArdle's disease, [ 2 ] is a metabolic disorder, one of the metabolic myopathies, more specifically a muscle glycogen storage disease, caused by a deficiency of myophosphorylase. [ 3 ][ 4 ] Its incidence is reported as one in 100,000, roughly the same as glycogen storage ...
Complications of diabetes are secondary diseases that are a result of elevated blood glucose levels that occur in diabetic patients. These complications can be divided into two types: acute and chronic. Acute complications are complications that develop rapidly and can be exemplified as diabetic ketoacidosis (DKA), hyperglycemic hyperosmolar ...
Each of these hormones has a different responsibility to keep blood glucose regulated; when blood sugar is too high, insulin tells muscles to take up excess glucose for storage in the form of glycogen. Glucagon responds to too low of a blood glucose level; it informs the tissue to release some glucose from the glycogen stores.
If the blood glucose level falls to dangerously low levels (as during very heavy exercise or lack of food for extended periods), the alpha cells of the pancreas release glucagon, a peptide hormone which travels through the blood to the liver, where it binds to glucagon receptors on the surface of liver cells and stimulates them to break down glycogen stored inside the cells into glucose (this ...
In glycogen storage diseases, however, glycogen cannot be properly broken down, leading to inappropriately decreased glucose levels in a fasting state, and thus hypoglycemia. [3] The glycogen storage diseases associated with hypoglycemia include type 0 , type I , type III , and type IV , as well as Fanconi syndrome .
