Hardy Diagnostics is an American company that manufactures and sells bacteriological culture media, reagents, automated microscope slide staining machines, and rapid identification kits for microbiological testing in clinical, research, and industrial laboratories. The company's culture media is useful in the detection of bacterial pathogens ...
[2] [7] The symptoms of short-chain acyl-CoA dehydrogenase deficiency may be triggered during illnesses such as viral infections. In some cases, signs and symptoms may not appear until adulthood, when some individuals may develop muscle weakness, while other individuals mild symptoms may never be diagnosed. [2] [5]
Mutations also cause 3-hydroxyacyl-CoA dehydrogenase deficiency. There are a wide variety of mutations that have been identified to cause this disease. Among them are missense mutations (A40T, P258L, D57G, Y226H) and nonsense mutations (R236X) in the protein, and splicing mutations (261+1G>A, 710-2A>G) and some small deletions (587delC) in the ...
Conversely, these antibodies are absent in people who take statin medications but do not have myopathy. Thus, the presence of anti-HMG CoA reductase antibodies in someone who uses a statin and has myopathy strongly supports the diagnosis. [3] CK levels increase to 10-100 times above normal (2000–20,000 IU/L) in more than 90% of cases.
Coenzyme A (CoA, SHCoA, CoASH) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle. All genomes sequenced to date encode enzymes that use coenzyme A as a substrate , and around 4% of cellular enzymes use it (or a thioester ) as a substrate.
Medium-chain acyl-CoA dehydrogenase deficiency (MCAD deficiency or MCADD) is a disorder of fatty acid oxidation that impairs the body's ability to break down medium-chain fatty acids into acetyl-CoA. The disorder is characterized by hypoglycemia and sudden death without timely intervention, most often brought on by periods of fasting or vomiting.
VLCAD (very long-chain-acyl-dehydrogenase) deficiency is exclusively linked to genetic mutations in DNA. A change of the gene that codes for very long-chain-acyl-CoA-dehydrogenase (VLCAD) results in a deficiency or malfunction of the produced VLCAD enzyme. [7] This mutation occurs on chromosome 17 and can be altered via a variety of pathways. [4]
An additional class of acyl-CoA dehydrogenase was discovered that catalyzes α,β-unsaturation reactions with steroid-CoA thioesters in certain types of bacteria. [ 8 ] [ 9 ] This class of ACAD was demonstrated to form α 2 β 2 heterotetramers, rather than the usual α 4 homotetramer, a protein architecture that evolved in order to accommodate ...
