Molecular classification of nemaline myopathies: “nontyping” specimens exhibit unique patterns of gene expression

Neurobiology of Disease, 2004
Nemaline myopathy (NM) is a slowly progressive or nonprogressive neuromuscular disorder caused by mutations in genes encoding skeletal muscle sarcomeric thin filament proteins. It is characterized by great heterogeneity at the clinical, histopathological,

RNA‐Seq of Cultured Peripheral Blood Lymphocytes Improves Identification of Cryptic Splicing Defects in Rare Disease Diagnostics

Human Mutation, Volume 2026, Issue 1, 2026.
Accurate identification of the genetic determinants of rare diseases is essential for effective recurrence‐risk management and informed reproductive decision‐making. Although whole‐exome sequencing (WES) and whole‐genome sequencing (WGS) have significantly improved diagnostic capabilities, a subset of affected families still receives no definitive ...

Case report: A novel ACTA1 variant in a patient with nemaline rods and increased glycogen deposition

Frontiers in Neurology
BackgroundCongenital myopathies are a group of heterogeneous inherited disorders, mainly characterized by early-onset hypotonia and muscle weakness. The spectrum of clinical phenotype can be highly variable, going from very mild to severe presentations ...

Counting the Cost: The Hidden Financial Realities of Neuromuscular Disease Through Patient and Family Perspectives

Health Expectations, Volume 28, Issue 6, December 2025.
ABSTRACT Introduction Neuromuscular diseases (NMDs) impose multifaceted challenges on individuals and their families, often resulting in significant medical and non‐medical expenses. While cost‐of‐illness (COI) studies provide valuable quantitative data, few explore the lived experience of financial strain.

Nemaline myopathy.

Archives of pathology & laboratory medicine, 1978
Nemaline myopathy occurred sporadically in a 59-year-old woman. She had slowly progressive weakness. A muscle biopsy specimen showed nemaline rods, increased variation in fiber size, apparent loss of Type IIb fiber differentiation, and a "moth-eaten" pattern of the intermyofibrillar network.

Collagenase treatment does not impair fiber contractile function in muscle biopsies from children with cerebral palsy

Physiological Reports, Volume 13, Issue 21, November 2025.
Abstract Cerebral palsy (CP) often presents with increased passive stiffness of the skeletal muscles, primarily due to increased collagen in the extracellular matrix. Collagenase from Clostridium histolyticum (CCH), an enzyme that degrades collagen, is used clinically to treat fibrotic conditions such as Dupuytren's contracture and Peyronie's disease ...

Potential cytotoxicity of truncated slow skeletal muscle troponin T (ssTnT) in a loss of function TNNT1 myopathy mouse model

The FEBS Journal, Volume 292, Issue 20, Page 5525-5539, October 2025.
A loss of function TNNT1 myopathy mouse model with the nonsense mutation p.E180* showed potential cytotoxicity of the truncated slow troponin T fragment. The mRNA expression profile in the soleus muscle of Tnnt1‐p.E180* mice showed very different changes in comparison to that of Tnnt1‐knockout mice.

Phenotypes of Myopathy-related Actin Mutants in differentiated C2C12 Myotubes

BMC Cell Biology, 2007
Background About 20 % of nemaline myopathies are thus far related to skeletal muscle alpha-actin. Seven actin mutants located in different parts of the actin molecule and linked to different forms of the disease were selected and expressed as EGFP-tagged

Optogenetic methods to stimulate gamma motor neuron axons ex vivo

Experimental Physiology, Volume 110, Issue 10, Page 1531-1541, October 1, 2025.
Abstract It is challenging to stimulate gamma motor neurons, which are important regulators of muscle spindle afferent function, without also recruiting alpha motor neurons. Here, we test the feasibility of stimulating gamma motor neuron axons using optogenetics in two transgenic mouse lines. We used an ex vivo muscle–nerve preparation in adult mice to
