Congenital myopathies 1 – nemaline

Congenital myopathies are a heterogeneous group of hereditary primary muscle disorders that are present from birth, although their onset may be delayed until later in infancy or early childhood. The most common of these rare disorders are nemaline myopathy, central core disease, centronuclear (myotubular) myopathies, and congenital fiber type disproportion. Among them, nemaline myopathy, a rare congenital myopathy, is characterized by generalized muscle weakness, respiratory insufficiency, and the presence of rod structures on muscle biopsy, which is caused by mutations in at least 13 known genes.
