Mutations in the gene encoding nebulin (NEB) are known to cause several types of congenital myopathy including recessive nemaline myopathy and distal nebulin myopathy.
This report illustrates that core-rod congenital myopathy with foot-drop is frequently associated with NEB gene mutations and should be considered in the differential diagnosis of early onset distal myopathies.
Although mutations in the gene encoding nebulin (NEB) are a frequent cause of nemaline myopathy, the most common non-dystrophic congenital myopathy, the mechanisms by which mutations in NEB cause muscle weakness remain largely unknown.
Nemaline myopathy (NM) is the most common congenital myopathy and is caused by mutations in various genes including NEB (nebulin), TPM2 (beta-tropomyosin), TPM3 (gamma-tropomyosin), and ACTA1 (skeletal alpha-actin).
LVhMyoD transduced cells readily formed striated, multinucleate myotubes expressing a wide range of genes associated with muscular dystrophy (dystrophin, dysferlin, sarcoglycans, caveolin-3) and congenital myopathy (nebulin, actin, desmin, tropomyosin, troponin).
