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 WebThe myofibrillar myopathies are a heterogeneous group of genetic disorders characterized pathologically by disruption of myofibrils and accumulation of degradation products in …
WebFrom MedlinePlus GeneticsMyosin storage myopathy is a condition that causes muscle weakness (myopathy) that does not worsen or worsens very slowly over time. This condition is characterized by the formation of protein clumps, which contain a protein called myosin, within certain muscle fibers. WebFeb 6, 2024 · Congenital myopathies are a vast group of genetic muscle diseases. Among the causes are mutations in the MYH2 gene resulting in truncated type IIa myosin heavy chains (MyHCs). The precise cellular and molecular mechanisms by which these mutations induce skeletal muscle symptoms remain obscure.
