Nemaline myopathy 8

Nemaline myopathy-8 is a severe autosomal recessive muscle disorder characterized by fetal akinesia or hypokinesia, followed by contractures, fractures, respiratory failure, and swallowing difficulties apparent at birth. Most patients die in infancy. Skeletal muscle biopsy shows numerous small nemaline bodies, often with no normal myofibrils (summary by Ravenscroft et al., 2013). For a discussion of genetic heterogeneity of nemaline myopathy, see NEM3 (161800).
