This condition is characterized by the formation of protein clumps, which contain a protein called myosin, within certain muscle fibers.
WebMyosinopathies are a heterogeneous group of congenital myopathies clinically ranging from late onset mild muscle dysfunction to early lethal symptomatic manifestations [1,2]. They are associated with mutations in the MYH3, MYH8, MYH7, MYH2, MYH1 and MYH4 genes, all encoding for myosin heavy chain isoforms present in the foetus, neonatal and/or WebA firm foundation is provided for molecular analysis in patients with suspected primary skeletal myosinopathies and for detailed modelling of the hypervariable surface loops which dictate myosin's kinetic properties. Myosin heavy chain (MyHC) is the major contractile protein of muscle. We report the first complete cosmid cloning and definitive ...
