Carnitine deficiency is one of a group of metabolic muscle diseases that interferes with the processing of food (in this case, fats) for energy production. Acid maltase deficiency (AMD) is an autosomal recessive disease characterized by an excessive accumulation of glycogen within lysosome-derived vacuoles in nearly all types of cells. Acid Maltase Deficiency Beyond Muscle Glycogen Accumulation Juan M. Pascual, MD, PhD; Charles R. Roe, MD Importance: The physiological relevance of acid malt-ase (acid -glucosidase, an enzyme that degrades lyso-somal glycogen) is well recognized in liver and muscle. The Journal of Pediatrics is an international peer-reviewed journal that advances pediatric research and serves as a practical guide for pediatricians who manage health and diagnose and treat disorders in infants, children, and adolescents.The Journal publishes original work based on standards of excellence and expert review.

Pompe, who first described an infant with the disease in 1932. 35 talking about this. Pompe's disease (acid maltase deficiency) classically affects infants and children, with a few sporadic cases occurring in adults. Pompe disease is a genetic disorder in which complex sugar called glycogen builds up in the body’s cells. Weaning failure was followed by diffuse pneumonia and death. At this time there is no cure for Pompe disease. There is one FDA approved treatment called Myozyme which is an enzyme replacement therapy produced by Genzyme Therapeutics. Enzyme replacement therapy (ERT) works by replacing some of the missing enzyme in Pompe disease patients’ bodies through lifetime IV infusions of Myozyme every other week. Widespread reversal of glycogen accumulation in the AAG-knockout mouse after AD vector delivery of the AAG cDNA to the liver Andy Amalfitano. cause of acid maltase deficiency or pompe disease Pompe disease is caused by a complete or partial deficiency of the lysosomal enzyme, alpha-glucosidase. Neurol Clin. 1 year. Aldolase A deficiency. The GAA gene provides instructions for producing an enzyme called acid alpha-glucosidase (also known as acid maltase).

The National Library of Medicine (NLM), on the NIH campus in Bethesda, Maryland, is the world's largest biomedical library and the developer of electronic information services that delivers data to millions of scientists, health professionals and members of the public around the globe, every day. What are the symptoms of carnitine deficiency? In patients with AMD, these mutations cause the acid alpha-glucosidase enzyme to lose most or all … Patients with AMD have a defect, or mutation, in a gene that functions in muscles, called the Acid Alpha-Glucosidase (GAA) gene. Normally, this gene makes a protein called the acid alpha-glucosidase enzyme (also called the acid maltase enzyme). Another common deficiency is an absence of alpha-galactosidase, which can help break down the carbohydrates found in legumes and beans. This genetic mutation causes a substance called glycogen … Glycogen storage disease type 2, also known as Pompe disease or acid maltase deficiency disease, is an inherited metabolic disorder. The adult form of acid maltase deficiency appears to be both clinically and genetically rather homogeneous; decrease of β‐glucosidase activity is the final common pathway leading to destruction of muscle fibers and progression of muscle weakness over a period of years. All patients had developed their initial pelvic girdle symptoms late in the second or early in the third decade and some years later developed signs of respiratory insufficiency. This condition is rare in the general public. In addition to the infantile lethal form of glycogen storage disease with cardiomyopathy (GSD Type IIa, Pompe disease) 1,4 glucosidase or acid maltase deficiency has been reported in a few children and adults (GSD Type IIb or IIc) erroneously thought to have muscular dystrophies.

A glycerol amino acid B amino acid fatty acid C fatty acid glycerol D glycerol fatty acid (h) The diagram shows a sperm cell. The Basics Name: Tiffany House. The disease results from the deficiency of an enzyme called acid alfa glucosidase (GAA), which breaks downs complex sugars in the body. This buildup occurs in organs and tissues, especially in muscles, causing them to break down. Pompe's disease, glycogen-storage disease type II, and acid maltase deficiency are alternative names for the same metabolic disorder. Acid maltase deficiency in adults is associated with progressive muscle weakness and may effect respiratory muscles resulting in respiratory failure. Acid alpha-glucosidase, also called α-1,4-glucosidase and acid maltase, is an enzyme (EC 3.2.1.20) that helps to break down glycogen in the lysosome.It is functionally similar to glycogen debranching enzyme, but is on a different chromosome, processed differently by the cell and is located in the lysosome rather than the cytosol. The structural gene is located on chromosome 17 … Acid Maltase Deficiency Association (AMDA) Association for Glycogen Storage Disease. Pompe's disease is also regarded as a muscular disorder, but the generalised storage of glycogen causes more than … What is acid maltase deficiency (also called AMD, Pompe disease, glycogenosis type 2, acid-alpha glucosidase deficiency, lysosomal storage disease)?

The other types of glycogen storage myopathies are considered static in that they are associated with fixed weakness rather than dynamic symptoms and signs. The Acid Maltase Deficiency Association, Inc. (AMDA) is a non-profit organization directed toward the advancement of research in acid maltase deficiency (also known as Pompe's disease). Hip flexion weakness may be the only finding in the earliest stages of this disease. Acid maltase deficiency is a metabolic muscle disorder, a group of diseases that interferes with the processing of food (in this case, carbohydrates) for energy production. Mutations in the GAA gene cause Pompe disease. People with this condition cannot break down the sugars sucrose and maltose, and other compounds made from simple sugar molecules (carbohydrates), which can cause diarrhea, abdominal pain, and other symptoms. • Daily urinary excretion of acid maltase (12.78 ± 2.10 units/24 hr/mg of creatinine, in 11 normal adults) was significantly decreased in ten patients with late-onset acid maltase deficiency (1.33 ± O.16 units/24 hr; P <.001) and 11 heterozygotes (3.27 ± 0.62 units/24 hr; P <.001). Adult pathology. The assay indicates that, just as in infantile and childhood cases, adult cases of the disease are transmitted by autosomal recessive inheritance. Pompe disease, also known as acid maltase deficiency and glycogen storage disease type II, is a glycogen storage disorder that is caused by a specific gene called GAA not working correctly. Overview.

Patients with AMD have a defect, or mutation, in a gene that functions in muscles, called the acid alpha-glucosidase (GAA) gene. At autopsy, profound muscle replacement by fibrofatty tissue was noted in the tongue and diaphragm, while the accessory and non respiratory muscles were variably preserved. Histochemistry and electronmicroscopy of muscle biopsies showed lysosomal glycogen storage resembling acid maltase deficiency. It is a pan-ethnic autosomal recessive trait characterised by acid α-glucosidase deficiency leading to lysosomal glycogen storage. Acid maltase deficiency in adults is associated with progressive muscle weakness and may effect respiratory muscles resulting in respiratory failure.
