At present there is no curative treatment for individuals suffering from myofibrillar myopathy. Treatment is aimed at alleviating the symptoms; strengthen muscle power so that patient can live comfortable life. [tandurust.com]
Prognosis
Treatment [ edit ] There is currently no cure for the disease but treatments to help the symptoms are available. [3] Prognosis [ edit ] Prognosis strongly depends on which subtype of disease it is. [en.wikipedia.org]

Etiology
They are organised into groups, and further divided into clinical, etiological or histopathological sub-types. [orpha.net]

Pathophysiology
This form has a wide range of symptoms and varies depending on the mutation made. [3] Pathophysiology [ edit ] The sarcomeres become misaligned and result in the disorganization of muscle fibers. [1] This mutation also results in muscle cell death by [en.wikipedia.org]
Prevention
This protein may have an important role to prevent the formation of intermediate filaments, in which formation mechanism involved other proteins such as desmin. Mutations in the gene CRYAB, give rise to type 2 myofibrillar myopathy (MFM2). [ivami.com]
Not only did this mean the aggregates were not removed but the other pathways were prevented from taking over. [medicalxpress.com]
This condition enlarges (dilates) and weakens the cardiac muscle, preventing it from pumping blood efficiently. [ghr.nlm.nih.gov]
