Myofibrillar myopathy (MFM) describes a group of skeletal and cardiac muscle disorders, defined by the disintegration of myofibrils and aggregation of degradation products into intracellular inclusions, and is typically clinically characterized by slowly-progressive muscle weakness, which initially involves the distal muscles, but is highly variable and that can affect the proximal muscles as well as the cardiac and respiratory muscles in some patients.
Biomarker and diagnostic research for myofibrillar myopathy has been reported in the published literature.
Estimated prevalence: Unknown (Unknown prevalence).
1 clinical trial registered, 1 recruiting. Interventions under study include medical devices. Research is primarily sponsored by academic and government institutions.
58 publications have been identified in PubMed for myofibrillar myopathy. Research spans Case Report / Case Series (34%), Basic Science / Preclinical (34%), and Epidemiology / Natural History (12%).
