Initial therapy usually includes oral prednisone at a dose of 1 mg per kilogram of body weight per day. Combatting Modern Slavery and Human Trafficking Statement, 3-Hydroxy-3-Methylglutaryl-Coenzyme A Reductase. Regenerating myocytes express even higher levels of HMG-CoA reductase. IgG antibodies to 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) are mainly associated with necrotizing autoimmune myopathy (NAM) in a subset of statin-treated patients. A paraneoplastic basis should be considered, according to age, sex, and other risk factors. Statin-associated autoimmune myopathy (SAAM) is a very rare form of muscle damage caused by the immune system in people who take statin medications. Anti-HMG-CoA reductase Antibody detects level of HMG-CoA reductase & has been published & validated for use in Immunoprecipitation, Western Blotting. Expression of HMG-CoA reductase is low in most tissues, but it is markedly increased when muscle and other types of cells are exposed to statins. Competitive inhibitors of the reductase induce the … Human(3156) Summary: HMG-CoA reductase is the rate-limiting enzyme for cholesterol synthesis and is regulated via a negative feedback mechanism mediated by sterols and non-sterol metabolites derived from mevalonate, the product of the reaction catalyzed by reductase. MABS1233, validated for use in Immunocytochemistry, Immunoprecipitation, and Western Blotting. Binding of statin to HMG-CoA reductase may alter protein conformation, exposing cryptic epitopes to which the immune system is not tolerant, leading to autoimmunity. Anti–HMG-CoA reductase autoantibodies have not been detected in statin-treated patients who do not have muscle disease. Freeman MW et al.

Parikh, J. Tavee, P. Soltanzadeh, A.L. In mammalian cells, HMG-CoA reductase is regulated by multiple mechanisms. Autoimmune myopathy has an insidious onset and a protracted course. This target gene encodes the protein '3-hydroxy-3-methylglutaryl-CoA reductase' in humans and may also be known as LDLCQ3, 3-hydroxy-3-methylglutaryl-Coenzyme A reductase, and 3-hydroxy-3-methylglutaryl CoA reductase (NADPH). Tested on 20 paraffin-embedded human tissues. Recently, a new myositis syndrome was described in association with antibodies directed against the pharmacologic target of statins, anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR antibody). Images. The 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA reductase) enzyme is a ubiquitously expressed glycoprotein that is bound to the membrane of the endoplasmic reticulum (ER), but also projects an active C-terminal catalytic tail into the cytoplasm. Unless the patient has only mild weakness, another immunosuppressive drug, , should be included at the outset. HMG-CoA reductase is the rate-limiting enzyme for cholesterol synthesis and is regulated via a negative feedback mechanism mediated by sterols and non-sterol metabolites derived from mevalonate, the product of the reaction catalyzed by reductase. Reference range is 0-20 units. Reporting Name Lists a shorter or abbreviated version of the Published Name for a test.

Sample Type Serum, Plasma, Tissue Homogenate Analytical Method Quantitative Specificity This assay has high sensitivity and excellent specificity for detection of human HMG-CoAR. HMG-CoA reductase (3-hydroxy-3-methyl-glutaryl-CoA reductase or HMGR) (EC 1.1.1.34) is a transmembrane protein involved in the mevalonate pathway, the metabolic pathway that produces cholesterol from acetyl-CoA. Therefore, a positive test for anti–HMG-CoA reductase autoantibodies in patients who develop muscle weakness after stain therapy strongly supports the diagnosis of an autoimmune disorder. Please note: not all lab locations offer all services. Recently, a new myositis syndrome was described in association with antibodies directed against the pharmacologic target of statins, anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR antibody).

Separate serum from cells within one hour of collection. Class II HLA allele DRB1*11:01 is strongly associated with the development of anti–HMG-CoA reductase autoantibodies, even in patients without known exposure to statins. New immunoassays for anti-HMG-CoA reductase antibodies may lead to incorrect diagnosis in inflammatory myositis. Tested on 20 paraffin-embedded human tissues. Therefore, a positive test for anti–HMG-CoA reductase autoantibodies in patients who develop muscle weakness after stain therapy strongly supports the diagnosis of an autoimmune disorder. It is found in the endoplasmic reticulum. The myopathy usually persists or worsens even if statin therapy is discontinued. HMG-CoA reductase is the rate-limiting enzyme for cholesterol synthesis and is regulated via a negative feedback mechanism mediated by sterols and non-sterol metabolites derived from mevalonate, the product of the reaction catalyzed by reductase. In most cases, autoimmune myopathy is refractory to treatment with glucocorticoids alone. Supplier Product Quantity Reactivity ?

Statins can produce rhabdomyolysis through two distinct mechanisms; a direct toxic effect and the induction of autoantibodies to the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMGCR). It is the rate-limiting enzyme in the mevalonate pathway as it catalyzes the conversion of HMG CoA to mevalonate, which is a critical precursor protein in the synthesis of sterols such as cholesterols. master code : NBP2-61616. 2012;64:4087-4093 © 2020 Laboratory Corporation of America® Holdings.
