An adult nemaline myopathy patient with respiratory and heart failure harboring a novel NEB variant

eNeurologicalSci, 2020
Nemaline myopathy is a heterogeneous disorder of skeletal muscle, and histologically characterized by the presence of nemaline bodies in muscle fibers. Patients with typical congenital form of nemaline myopathy initially present with proximal but later ...

A Homozygous Deep Intronic Mutation Alters the Splicing of Nebulin Gene in a Patient With Nemaline Myopathy

Frontiers in Neurology, 2021
Nemaline myopathy is a rare disorder affecting the muscle sarcomere. Mutations in nebulin gene (NEB) are known to be responsible for about 50% of nemaline myopathy cases.

Testing of therapies in a novel nebulin nemaline myopathy model demonstrate a lack of efficacy

Acta Neuropathologica Communications, 2018
Nemaline myopathies are heterogeneous congenital muscle disorders causing skeletal muscle weakness and, in some cases, death soon after birth. Mutations in nebulin, encoding a large sarcomeric protein required for thin filament function, are responsible ...

Molecular signatures of inherited and acquired sporadic late onset nemaline myopathies

Acta Neuropathologica Communications, 2023
Acquired sporadic late onset nemaline myopathy (SLONM) and inherited nemaline myopathy (iNM) both feature accumulation of nemaline rods in muscle fibers. Unlike iNM, SLONM is amenable to therapy.

Filamentous tangles with nemaline rods in MYH2 myopathy: a novel phenotype

Acta Neuropathologica Communications, 2021
The MYH2 gene encodes the skeletal muscle myosin heavy chain IIA (MyHC-IIA) isoform, which is expressed in the fast twitch type 2A fibers. Autosomal dominant or recessive pathogenic variants in MYH2 lead to congenital myopathy clinically featured by ...

Generation of two isogenic induced pluripotent stem cell lines from a 10-year-old typical nemaline myopathy patient with a heterozygous dominant c.541G>A (p.Asp179Asn) pathogenic variant in the ACTA1 gene

Stem Cell Research, 2021
Nemaline myopathy (NM) is a congenital myopathy typically characterized by skeletal muscle weakness and the presence of nemaline bodies in myofibres. Approximately 25% of NM cases are caused by variants in ACTA1. We generated two induced pluripotent stem

neb: a zebrafish model of nemaline myopathy due to nebulin mutation

Disease Models & Mechanisms, 2012
SUMMARY Nemaline myopathy is one of the most common and severe non-dystrophic muscle diseases of childhood. Patients typically present in infancy with hypotonia, weakness, delayed motor development, and bulbar and respiratory difficulties.

Generation of two isogenic induced pluripotent stem cell lines from a 4-month-old severe nemaline myopathy patient with a heterozygous dominant c.553C > A (p.Arg183Ser) variant in the ACTA1 gene

Stem Cell Research, 2021
Nemaline myopathy (NM) is a congenital myopathy typically characterized by skeletal muscle weakness and the presence of abnormal thread- or rod-like structures (nemaline bodies) in myofibres.

Coexistence of central nucleus, cores, and rods: Diagnostic relevance

Annals of Indian Academy of Neurology, 2016
Background: Congenital myopathies (CMs) though considered distinct disorders, simultaneous occurrence of central nucleus, nemaline rods, and cores in the same biopsy are scarcely reported. Objective: A retrospective reassessment of cases diagnosed as CMs

Camptocormia as the presenting symptom in sporadic late onset nemaline myopathy: a case report

BMC Musculoskeletal Disorders, 2019
Background Camptocormia has been reported in a plethora of diseases comprising disorders of the central nervous system, the peripheral nervous system, and the neuromuscular junction as well as hereditary and acquired myopathies.
