Pleiotropic Effects of the NSAID Fenamates on Chloride Channels: Opportunity for Ion Channelopathies?

Pharmacology Research &Perspectives, Volume 13, Issue 4, August 2025.
ABSTRACT Chloride channels are involved in many cellular processes, including cell volume regulation, modulation of cell excitability, and electrolyte and water secretion. Mutations of these proteins are associated with heterogeneous diseases such as myotonia, cystic fibrosis, epilepsy, deafness, lysosomal storage disease, and various kinds of renal ...

Myo‐Guide: A Machine Learning‐Based Web Application for Neuromuscular Disease Diagnosis With MRI

Journal of Cachexia, Sarcopenia and Muscle, Volume 16, Issue 3, June 2025.
ABSTRACT Background Neuromuscular diseases (NMDs) are rare disorders characterized by progressive muscle fibre loss, leading to replacement by fibrotic and fatty tissue, muscle weakness and disability. Early diagnosis is critical for therapeutic decisions, care planning and genetic counselling.

Clinical and Molecular Spectrum of Myotonia and Periodic Paralyses Associated With Mutations in SCN4A in a Large Cohort of Italian Patients

Frontiers in Neurology, 2020
Background: Four main clinical phenotypes have been traditionally described in patients mutated in SCN4A, including sodium-channel myotonia (SCM), paramyotonia congenita (PMC), Hypokaliemic type II (HypoPP2), and Hyperkaliemic/Normokaliemic periodic ...

Anesthesia Experience in a Patient with Myotonia Congenita

Bagcilar Medical Bulletin, 2019
Myotonia congenita (MC) was first described as a skeletal muscle disorder by Thomsen in 1876. As a result of the mutation of the chloride channel gene (CLCN1), which is on the 17th chromosome, patients suffer from muscle contractility and fatigue ...

MYL1‐Related Congenital Myopathy: Clinical, Genetic and Pathological Insights

Neuropathology and Applied Neurobiology, Volume 51, Issue 3, June 2025.
This study describes two individuals with severe congenital myopathy caused by novel biallelic MYL1 variants. Detailed muscle analyses revealed selective type II fibre hypotrophy, aberrant myofibrillogenesis, and signs of autophagic impairment. The findings expand the clinical and pathological spectrum of MYL1‐related myopathy and suggest a broader ...

In vivo assessment of muscle membrane properties in myotonic dystrophy [PDF]

, 2016
INTRODUCTION: Myotonia in myotonic dystrophy types 1 (DM1) and 2 (DM2) is generally attributed to reduced chloride channel conductance. We used muscle velocity recovery cycles (MVRCs) to investigate muscle membrane properties in DM1 and DM2, with ...

Genetics update: monogenetics, polygene disorders and the quest for modifying genes [PDF]

, 2018
The genetic channelopathies are a broad collection of diseases. Many ion channel genes demonstrate wide phenotypic pleiotropy, but nonetheless concerted efforts have been made to characterise genotype-phenotype relationships.
