Anesthetic management of a patient with sodium-channel myotonia: a case report
Background Sodium-channel myotonia (SCM) is a nondystrophic myotonia, characterized by pure myotonia without muscle weakness or paramyotonia. The prevalence of skeletal muscle channelopathies is approximately 1 in 100,000, and the prevalence of SCM is ...

Structure of the CLC-1 chloride channel from Homo sapiens. [PDF]
CLC channels mediate passive Cl- conduction, while CLC transporters mediate active Cl- transport coupled to H+ transport in the opposite direction. The distinction between CLC-0/1/2 channels and CLC transporters seems undetectable by amino acid sequence.

Cromakalim (BRL 34915) restores in vitro the membrane potential of depolarized human skeletal muscle fibres [PDF]
The purpose of the present study was to analyze the effects of cromakalim (BRL 34915), a potent drug from a new class of drugs characterized as K+ channel openers, on the electrical activity of human skeletal muscle.

Predominantly myalgic phenotype caused by the c.3466G > A p.A1156T mutation in SCN4A gene [PDF]
Objective: To characterize the clinical phenotype in patients with p.A1156T sodium channel mutation. Methods: Twenty-nine Finnish patients identified with the c.3466G>A p.A1156T mutation in the SCN4A gene were extensively examined. In a subsequent study,

Genetic neurological channelopathies: molecular genetics and clinical phenotypes [PDF]
Evidence accumulated over recent years has shown that genetic neurological channelopathies can cause many different neurological diseases. Presentations relating to the brain, spinal cord, peripheral nerve or muscle mean that channelopathies can impact ...

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

Efficacy of Retigabine in Treating Weakness in a Mouse Model of Hypokalemic Periodic Paralysis
ABSTRACT Introduction/Aims Hypokalemic periodic paralysis (HypoKPP) is an ion channelopathy causing episodic skeletal muscle weakness triggered by hypokalemia. Reduced inward rectifier K+ (Kir) channel activity contributes to membrane depolarization and paralysis, suggesting that pharmacologic activation of muscle K+ channels may restore excitability ...
