Definition and Characteristics
Autosomal-recessive or autosomal-dominant congenital myopathies marked by generalized muscle weakness and the formation of nemaline bodies/rods in muscle fibers caused by mutations in at least six different genes .
No prevalence figures have been published. An estimated incidence is 0.02 per 1,000 live births .
So far, five different genes have been identified as being responsible for nemaline myopathies, NEM 1–6, (Table 1). In addition, two loci have been identified for the rare core-rod myopathies, where both cores and rods can be found in the muscle fibers.
Molecular and Systemic Pathophysiology
Nemaline myopathies are considered a heterogeneous group of disorders which may be classified according to clinical features as encompassing six different types. Nemaline myopathies have been linked to at least six different loci, NE ...
