The two major types of lesions in myofibrillar myopathy consist of hyaline spheroidal structures composed of compacted myofibrillar residues, and nonhyaline lesions that comprise foci of myofibrillar destruction.

Introduction: Myofibrillar myopathy (MFM) is a rare human disease, characterized by a distinct histopathological pattern of myofibrillar degeneration and protein aggregates. LDB3 protein encoded by this gene is a key Z-disk protein that interacts with α-actinin and protein kinase C. Case Presentation: In this paper, we identified the novel heterozygous, and hence, dominant mutation in the LIM

Desmin-related myofibrillar myopathy is a subgroup of the myofibrillar myopathy diseases and is the result of a mutation in the gene that codes for desmin which prevents it from forming protein filaments, instead forming aggregates of desmin and other proteins throughout the cell. Presentation

Nonsyndromic deafness is hearing loss that is not associated with other signs and symptoms. In contrast, syndromic deafness involves hearing loss that occurs with abnormalities in other parts of the body. Accordingly, mice deficient for MuRF1 and MuRF3 develop a skeletal muscle myopathy and hypertrophic cardiomyopathy characterized by subsarcolemmal MHC accumulation, myofiber fragmentation, and diminished muscle performance. First described in 1983, Barth syndrome (BTHS) is widely regarded as a rare X-linked genetic disease characterised by cardiomyopathy (CM), skeletal myopathy, growth delay, neutropenia and increased urinary excretion of 3-methylglutaconic… Further sessions concentrated on the current understanding of the role of autophagy in several muscle disorders including Pompe disease, Danon disease, XMEA, laminopathies, GNE myopathy, centronuclear myopathies, myofibrillar myopathies… These spontaneous Dmdmdx mutant mice do not express dystrophin and may be useful for studying Duchenne muscular dystrophy.

A novel de novo mutation in the desmin gene causes desmin myopathy with toxic aggregates. Myopathy is a disease of the muscle in which the muscle fibers do not function properly. This results in muscular weakness. Myopathy means muscle disease (Greek : myo- muscle + patheia -pathy : suffering).This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the brain). Myofibrillar myopathy is a muscular disease and part of a group of disorders called muscular dystrophies. The condition is characterized by improper functioning of muscle fibers causing weakness Academia.edu is a platform for academics to share research papers.

An ultrastructural study of biopsied muscles was performed in seven patients with rimmed vacuolar distal myopathy, which This disambiguation page lists articles associated with the title DRM. If an internal link led you here, you may wish to change the link to point directly to the intended article. Skin fragility syndrome (also known as "plakophilin 1 deficiency") is a cutaneous condition characterized by trauma-induced blisters and erosions. For the template on this page, that currently evaluates to autocollapse. Normally, type I and type II muscle fibers show a checkerboard-like random distribution. However, when reinnervation occurs, the group of fibers associated with one nerve are of the same type. This could reflect a strong influence of conformational transition on the kinetics or the presence of alternative aggregation pathways.

A fifth myopathy, nemaline myopathy, is caused by muta-tions that affect filament pro-teins. When the filament proteins fail to do their jobs, muscles can’t contract properly, causing a loss of tone and strength. At least one myopathy (a type of myotubular myopathy) is caused by mutations in a muscle pro-tein required for normal muscle Since the frequency of sporadic myofibrillar myopathy appears to be high, 4 the desmin gene and possibly other unidentified genes may be hot spots for mutations. Download Citation DES gene mutations have also been shown to cause another form of cardiomyopathy called restrictive cardiomyopathy, in which the heart muscle is stiff and cannot fully relax after each contraction. Although cardiomyopathy is a sign of myofibrillar myopathy, these forms of cardiomyopathy are not associated with weakness of the skeletal muscles.
