Summaries for Nemaline Myopathy 8

About this section
UniProtKB/Swiss-Prot : 75 Nemaline myopathy 8: A severe form of nemaline myopathy. Nemaline myopathies are muscular disorders characterized by muscle weakness of varying severity and onset, and abnormal thread-like or rod-shaped structures in muscle fibers on histologic examination. NEM8 is 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.

MalaCards based summary : Nemaline Myopathy 8, is also known as nemaline myopathy 8, autosomal recessive. An important gene associated with Nemaline Myopathy 8 is KLHL40 (Kelch Like Family Member 40). Affiliated tissues include skeletal muscle and bone, and related phenotypes are dysphagia and facial palsy

Disease Ontology : 12 A nemaline myopathy characterized by fetal akinesia or hypokinesia, followed by contractures, fractures, respiratory failure, and swallowing difficulties apparent at birth that has material basis in homozygous or compound heterozygous mutation in the KLHL40 gene on chromosome 3p22.

OMIM : 57 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). (615348)
