Introduction A newly recognized disease of skeletal muscle was discovered recently in a 4-year-old girl. 1,2 The child had congenital, apparently nonprogressive, muscular weakness that was more severe proximally. In her biopsied skeletal muscle fibers were abnormal rod-shaped structures, which cytochemically appeared to be altered myofibrillar ...

Nemaline myopathy in the neonate
Neurology, 1983Nemaline myopathy, one of the more benign myopathies in older children and adults, may be associated with early death in the neonate and young infant even when there is no obvious clinical progression. Early diagnosis can be made by muscle biopsy in the neonate for aid in the decision-making, discussion with families, and genetic counseling.

Nemaline myopathy and cardiomyopathy
Pediatric Neurology, 1999A case report is presented in which a 4-year-old male is diagnosed with hypertrophic cardiomyopathy, respiratory distress, muscle hypotonia, and psychomotor retardation. Electron microscopic study of skeletal muscle biopsy revealed pathologic changes typical of congenital nemaline myopathy, and biochemical analysis revealed a disorder of mitochondrial ...

Muscle & Nerve, 1986
AbstractAn apparently inherited myopathy, characterized by the presence of large numbers of nemaline rods in skeletal muscle fibers, was investigated in five cats. Onset of signs varied from 6 months to 1.5 years of age and consisted of reluctance to move, jerky gait and muscle twitching, hyporeflexia, and muscle wasting, which was most prominent in ...

Neuromuscular Disorders, 1999 The nemaline myopathies are muscle disorders of variable severity and age of onset, with characteristic nemaline bodies in the sarcoplasm. Genes for dominant (NEM1) and recessive (NEM2A) nemaline myopathy have been localised to chromosomes one and two ...

Neuropediatrics, 1982
Two sisters with congenital nemaline myopathy are described. In both cases almost 70% of muscle fibers contained rods which were selectively localized in the larger ones. The variability coefficient was abnormally increased. Histochemical reactions showed that almost all the muscle fibers were type 1.

Progression in nemaline myopathy
Acta Neuropathologica, 1989Four of seven patients with nemaline myopathy had severe, rapidly progressing symptoms. These four showed an increase in acid phosphatase activity in muscle fibers demonstrated by histochemistry and cathepsin B&L activity by biochemical measurement. On electron microscopy, nemaline bodies, occasionally disorganized myofibrils and autophagic vacuoles ...

Hereditary Occurrence of Nemaline Myopathy
Archives of Neurology, 1965SINCE the original descriptions of nemaline myopathy in 1963 by Shy et al1,2in a four-yearold girl with pelvic and pectoral girdle weakness, other cases from different families have been described.3-5In none of these cases have muscle biopsies proved involvement of other members of the family with an exact disease process.

Nemaline and myotubular myopathies
Seminars in Pediatric Neurology, 2002Nemaline myopathy is caused by mutations in one of at least six different genes. The clinical picture also varies widely, in terms of the grade and the distribution of muscle weakness. In familial cases, autosomal-recessive inheritance is more common than autosomal-dominant inheritance, and in some patients the disorder is caused by new dominant ...

Journal of Neuro-Ophthalmology, 1997
Ophthalmoparesis and ptosis are extremely rare in nemaline myopathy. A 45-year-old man with a long history of bilateral ptosis and a 1-year history of diplopia is reported. Leg and arm weakness and wasting had been present since childhood, with a very slow deterioration over time.
