Immune-mediated necrotizing myopathy (IMNM), also called necrotizing autoimmune myopathy (NAM), is a rare but serious muscle disease strongly associated with autoantibodies to either signal recognition protein (SRP-IgG) or 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR-IgG). Our testing can provide earlier identification and treatment initiation in patients with IMNM, which is critical to preventing further harm.
2/3 of IMNM patients will be seropositive for HMGCR-IgG or SRP-IgG
