• Proximal Muscle Weakness

  Our index case complained of proximal muscle weakness at age 30. Her daughter presented at birth with a cardiomyopathy without any skeletal muscle involvement. [ncbi.nlm.nih.gov]

  It is characterised by the presence of subsarcolemmal hyaline bodies in type I muscle fibres and predominantly proximal muscle weakness. [plu.mx]

• Flushing

  Circular dichroism (CD) was measured using a Jasco J-810 spectropolarimeter (Jasco) with constant N 2 flushing. A Peltier temperature control device was used to perform all measurements at 4 °C and a rectangular 1-mm path length cell was used. [pnas.org]

• Suggestibility

  Our Drosophila models are the first to recapitulate the human MSM phenotype with ultrastructural inclusions, suggesting that the diminished ability of the mutant myosin to form stable thick filaments contributes to the dystrophic phenotype observed in [ncbi.nlm.nih.gov]

  We show that each MSM mutation has a different molecular phenotype, suggesting that there are multiple mechanisms by which MSM can be caused. [pnas.org]

[…] molecular and imaging level, myopathies due to MYH7 gene mutations, MYH7 gene analysis was conducted by RT-PCR/SSCP/sequencing in two patients diagnosed with myosin storage myopathy and 17 patients diagnosed with scapulo-peroneal myopathy of unknown etiology [ncbi.nlm.nih.gov]

Etiology It is caused by mutation of the MYH7 gene (14q11) that encodes the myosin heavy chain of type 1 fibers of skeletal muscle and cardiac ventricles (mutations have been identified in approximately 50% of individuals with MPD1). [orpha.net]

Discovery of markers that represent etiological determinants of cardiac disease require a shift of focus towards the signaling proteome. Therefore, a protein -class centered quantitative analysis of kinases, phosphatases and GTPases was adopted. [pubs.rsc.org]

Unlikely the other, more frequent forms of congenital myopathy, our findings also propose a progressive nature of MYH7 -related myopathies, and a striking difficulty in targeting the underlying molecular etiology. [ojrd.biomedcentral.com]

Summary Epidemiology MPD1 is rare, the prevalence is unknown. Clinical description Age at onset varies from 4 to 5 years to the early twenties. [orpha.net]

Pathophysiology [ edit ] Skeletal muscle, with myofibrils labeled at upper right and sarcoplasmic reticulum at bottom Muscle contraction begins with the brain setting off action potentials, which are waves in the electrical charges that extend along neurons [en.wikipedia.org]

A lack of sodium would prevent the sodium gradient from being strong enough to power the calcium pumps; the calcium ions would remain in the myofibrils, forcing the muscle to stay contracted and causing a cramp. [en.wikipedia.org]
