X-linked Emery-Dreifuss muscular dystrophy is caused by mutations in emerin, a novel nuclear membrane protein. Other major inherited neuromuscular diseases have now also been shown to involve proteins which localize and function at least partly in the cell nucleus. These include lamin A/C in autosomal dominant Emery-Dreifuss muscular dystrophy, SMN in spinal muscular atrophy, SIX5 in myotonic dystrophy, calpain3 in type 2A limb-girdle muscular dystrophy, PABP2 in oculopharyngeal dystrophy, androgen receptor in spinal and bulbar muscular atrophy and the ataxins in hereditary ataxias. This review compares the molecular basis for these various disorders and considers the role of cell death, including apoptosis, in their pathogenesis.
