Can Prenatal Ultrasound and Genetic Testing Reliably Exclude Non‐Isolated Clubfoot?

open access: yesPrenatal Diagnosis, Volume 46, Issue 1, Page 30-38, January 2026.
ABSTRACT Objective The aim of this study is to evaluate the efficacy of prenatal second trimester ultrasound in diagnosing isolated congenital clubfoot and to assess the role of prenatal genetic testing. Methods We conducted a retrospective cohort study in the North‐West region of the Netherlands with prenatally suspected clubfoot between 16 and 24 ...

Paxilline Prevents the Onset of Myotonic Stiffness in Pharmacologically Induced Myotonia: A Preclinical Investigation

open access: yesFrontiers in Physiology, 2020
Reduced Cl− conductance causes inhibited muscle relaxation after forceful voluntary contraction due to muscle membrane hyperexcitability. This represents the pathomechanism of myotonia congenita.

Gain of function mutants: Ion channels and G protein-coupled receptors [PDF]

open access: yes, 2000
Many ion channels and receptors display striking phenotypes for gain-of-function mutations but milder phenotypes for null mutations. Gain of molecular function can have several mechanistic bases: selectivity changes, gating changes including constitutive

Hyperthyroid Hypokalemic Periodic Paralysis in a Nepali Male; A Case Report

open access: yesClinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Hyperthyroid Hypokalemic Periodic Paralysis (HHPP), marked by acute weakness and hypokalemia. Prompt potassium replacement and hyperthyroidism management are essential to prevent life‐threatening outcomes. This case highlights its presentation in a Nepali male, reinforcing the need for high clinical suspicion.

Ion channels: structural basis for function and disease. [PDF]

open access: yes, 1996
Ion channels are ubiquitous proteins that mediate nervous and muscular function, rapid transmembrane signaling events, and ionic and fluid balance. The cloning of genes encoding ion channels has led to major strides in understanding the mechanistic basis

Fetal Akinesia/Hypokinesia and Arthrogryposis of Neuromuscular Origin: Etiologic Groups, Genetics, and Phenotypic Spectrum

open access: yesAnnals of Clinical and Translational Neurology, Volume 12, Issue 8, Page 1528-1547, August 2025.
ABSTRACT Objective To provide a comprehensive clinical and genetic characterization of individuals with arthrogryposis multiplex congenita (AMC), focusing on the distribution of genetic etiologies across the neuromuscular spectrum and comparing myogenic and neurogenic subtypes. Methods A total of 105 individuals with AMC were clinically and genetically

Molecular cloning of ion channels in Felis catus that are related to periodic paralyses in man: a contribution to the understanding of the genetic susceptibility to feline neck ventroflexion and paralysis [PDF]

open access: yes, 2014
Neck ventroflexion in cats has different causes; however, the most common is the hypokalemia associated with flaccid paralysis secondary to chronic renal failure.

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

open access: yesPharmacology 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 ...
