Nemaline Myopathy 10 (NEM10)

External Ids:

UniProtKB/Swiss-Prot: ⁷³ An autosomal recessive 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. NEM10 is characterized by early-onset generalized muscle weakness and hypotonia with respiratory insufficiency and feeding difficulties. Additional features include arthrogryposis or congenital contractures, ophthalmoplegia, a history of prematurity, reduced fetal movements, and polyhydramnios. Most patients die of respiratory failure in early infancy.

MalaCards based summary: Nemaline Myopathy 10, also known as nem10, is related to myopathy and locked-in syndrome, and has symptoms including ophthalmoplegia, generalized muscle weakness and facial paresis. An important gene associated with Nemaline Myopathy 10 is LMOD3 (Leiomodin 3). Affiliated tissues include skeletal muscle, and related phenotypes are facial palsy and skeletal muscle atrophy

OMIM®: ⁵⁷ Nemaline myopathy-10 is an autosomal recessive severe congenital myopathy characterized by early-onset generalized muscle weakness and hypotonia with respiratory insufficiency and feeding difficulties. Many patients present antenatally with decreased fetal movements, and most die of respiratory failure in early infancy (summary by Yuen et al., 2014). Patients with a stable and much milder disease course have been described (Schatz et al., 2018). For a discussion of genetic heterogeneity of nemaline myopathy, see NEM3 (161800).

Disease Ontology: ¹¹ A nemaline myopathy characterized by early-onset generalized muscle weakness and hypotonia with respiratory insufficiency and feeding difficulties that has material basis in homozygous or compound heterozygous mutation in the LMOD3 gene on chromosome 3p14.
