Values >4 indicate presence of antibodies to 3-Hydroxy-3-Methylglutaryl CoEnzyme A Reductase (HMGCR) and suggest autoimmune myopathy. IgG antibodies to HMGCR in the setting of muscle weakness and a raised CK are highly suggestive of an autoimmune necrotising myositis. HMGCR Antibody ← Return Test Information Test Name. HMGCR Antibody. Synonyms. 3-Hydroxy-3-Methylglutaryl CoEnzyme A Reductase; HMG CoA Reductase; extended myositis screen. Preferred Specimen.

Hmgcr antibody test

Back to Test Catalogue. Anti-HMGCR antibodies represent a characteristic serological feature of statin-exposed and statin-unexposed patients with immune-mediated necrotizing myopathy (IMNM). We assessed anti-HMGCR antibodies in patients with suspected IMNM following statin exposure and patients with other autoimmune rheumatic diseases. 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. In antibody-negative patients, alternative diagnoses should be considered. Anti-HMGCR myopathy was first recognized and characterized in patients with a history of statin exposure and immune-mediated necrotizing myopathy. After the discovery of anti-HMGCR autoantibodies, several international groups identified and characterized more patients, expanding the phenotypic spect … Acid phosphatase stain.

Anti-MDA5 (anti-CADM 140) HMGCR (3-hydroxy-3-methylglutaryl-coenzyme A reductase) is a key enzyme in the production of cholesterol. Patients who have anti-HMGCR antibodies and use statin medications to control high cholesterol may develop statin-induced necrotizing myopathy. Those who know they have this antibody should never take statins. HMGCR Antibody: Chronic Myopathy, Young onset.

Recently, auto-antibodies (AAbs) to the enzyme, 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) was shown to be a MSA HMGCR : Evaluating patients with suspected necrotizing autoimmune myopathy Measuring 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR) antibodies HMGCR - Overview: 3-Hydroxy-3-Methylglutaryl Coenzyme-A (HMG-CoA) Reductase, Serum 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. Although infrequent, these antibodies may also be observed in statin-naive patients with NAM. Strong clinical correlation is recommended in the absence of muscle fiber HMGCR : Necrotizing autoimmune myopathy (NAM) is a serious but rare muscle disease strongly associated with autoantibodies to either signal recognition protein (SRP) or 3-hydroxy-3-methylglutaryl-CoA reductase (HMGCR).(1) NAM typically manifests with subacute proximal limb muscle weakness and persistently elevated serum creatine kinase (CK) concentrations, but slower onsets can occur and complicate diagnosis.
