Glycerol kinase deficiency has two main causes.. The first cause is isolated enzyme deficiency. The enzyme glycerol kinase is encoded by the X-chromosome in humans. [8] It acts as a catalyst in the phosphorylation of glycerol to glycerol-3-phosphate which plays a key role in formation of triacylglycerol (TAG) and fat storage.
Hyperglycerolemia, also known as glycerol kinase deficiency (GKD), is a genetic disorder where the enzyme glycerol kinase is deficient resulting in a build-up of glycerol in the body. Glycerol kinase is responsible for synthesizing triglycerides and glycerophospholipids in the body. Excess amounts of glycerol can be found in the blood and/ or ...
glucosyltransferase I deficiency causes ALG6-CDG (CDG-Ic) [22] glucosyltransferase II deficiency causes ALG8-CDG (CDG-Ih). [23] Glc3Man9GlcNAc2-PP-Dol A protein with hitherto unknown activity, MPDU-1, is required for the efficient presentation of Dol-P-Man and Dol-P-Glc. Its deficiency causes MPDU1-CDG (CDG-If). [24]
Glycerol kinase, encoded by the gene GK, is a phosphotransferase enzyme involved in triglycerides and glycerophospholipids synthesis. Glycerol kinase catalyzes the transfer of a phosphate from ATP to glycerol thus forming glycerol 3-phosphate :
Mitochondrial pyruvate carrier deficiency (MPYCD) is a metabolic disorder, in which the transport of pyruvate from the cytosol to the mitochondria is affected (gene SLC54A1/BRP44L/MPC1 [6]); the deficiency is characterized by delayed psychomotor development and lactic acidosis with a normal lactate/pyruvate ratio resulting from impaired ...
Glycogen storage disease type IX is a hereditary deficiency of glycogen phosphorylase kinase B that affects the liver and skeletal muscle tissue. It is inherited in an X-linked or autosomal recessive manner. [1]
Generally, diseases outlined within the ICD-10 codes E70-E72 within Chapter IV: Endocrine, nutritional and metabolic diseases should be included in this category. The main article for this category is Inborn errors of amino acid metabolism .
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 disease type ...
