Congenital Myopathies in the New Millennium

Few medical disciplines have benefited so enormously from the molecular revolution as myology. Whereas the congenital myopathies have flourished from enzyme histochemistry and electron microscopy, defining individual congenital myopathies by structural abnormalities, genetic research has only recently focused on congenital myopathies. However, a number of congenital myopathies have been molecularly elucidated: central and multiminicore diseases, nemaline myopathy, myotubular myopathy, and congenital myopathy marked by aggregation of proteins, giving rise to the concept of protein aggregate myopathies, to which now desminopathies, -B crystallinopathies, selenoproteinopathy, myotilinopathy, actinopathies, and myosinopathies belong. Based on recent identification of mutations in respective genes, the principle "from morphology, that is, immunohistochemistry, to molecular analysis" through recognition of certain accrued proteins within muscle fibers and subsequent analysis of their respective genes has resulted in a wealth of genetic data and in reconsidering classification and nosologic interpretation of certain congenital myopathies. This heuristic principle needs to be further applied to other genetically still obscure congenital myopathies. (J Child Neurol 2005;20:94101).
