Nemaline myopathies: a current view [PDF]

, 2019
Nemaline myopathies are a heterogenous group of congenital myopathies caused by de novo, dominantly or recessively inherited mutations in at least twelve genes. The genes encoding skeletal α-actin (ACTA1) and nebulin (NEB) are the commonest genetic cause.

Mild clinical presentation in KLHL40-related nemaline myopathy (NEM 8) [PDF]

, 2016
International audienceNemaline myopathies are clinically and genetically heterogeneous muscle diseases characterized by the presence of nemaline bodies (rods) in muscle fibers. Mutations in the KLHL40 (kelch-like family member 40) gene (NEM 8) are common

Clinical and genetic features of infancy-onset congenital myopathies from a Chinese paediatric centre

BMC Pediatrics, 2022
Background Congenital myopathies are a group of rare neuromuscular diseases characterized by specific histopathological features. The relationship between the pathologies and the genetic causes is complex, and the prevalence of myopathy-causing genes ...

Actin Polymerization Defects Induce Mitochondrial Dysfunction in Cellular Models of Nemaline Myopathies

Antioxidants, 2023
Nemaline myopathy (NM) is one of the most common forms of congenital myopathy and it is identified by the presence of “nemaline bodies” (rods) in muscle fibers by histopathological examination.

Skeletal muscle microRNA and messenger RNA profiling in cofilin-2 deficient mice reveals cell cycle dysregulation hindering muscle regeneration. [PDF]

PLoS ONE, 2015
Congenital myopathies are rare skeletal muscle diseases presenting in early age with hypotonia and weakness often linked to a genetic defect. Mutations in the gene for cofilin-2 (CFL2) have been identified in several families as a cause of congenital ...

Shoulder Rotation Test: A New Test for Discriminating Between Functional and Structural Weakness. [PDF]

Brain Behav
We introduce the shoulder rotation test, a simple bedside test combining the MRC scoring of shoulder internal rotation (IR) and external rotation (ER), for discriminating between functional weakness (FW) and structural weakness (SW) of the upper limbs.
