Case report: Multiple approach analysis in a case of clinically assessed myotonia congenita [PDF]
Frontiers in GeneticsMyotonia congenita, both in a dominant (Thomsen disease) and recessive form (Becker disease), is caused by molecular defects in CLCN1 that encodes the major skeletal muscle chloride channel, ClC-1.

Myotonia congenita and periodic hypokalemia paralysis in a consanguineous marriage pedigree: Coexistence of a novel CLCN1 mutation and an SCN4A mutation. [PDF]
PLoS ONE, 2020 Myotonia congenita and hypokalemic periodic paralysis type 2 are both rare genetic channelopathies caused by mutations in the CLCN1 gene encoding voltage-gated chloride channel CLC-1 and the SCN4A gene encoding voltage-gated sodium channel Nav1.4.

A case report: autosomal recessive Myotonia congenita caused by a novel splice mutation (c.1401 + 1G > A) in CLCN1 gene of a Chinese Han patient [PDF]
BMC Neurology, 2018 Background Autosomal recessive Myotonia congenita (Becker’s disease) is caused by mutations in the CLCN1 gene. The condition is characterized by muscle stiffness during sustained muscle contraction and variable degree of muscle weakness that tends to ...

Clinical and genetic characteristics of myotonia congenita in Chinese population [PDF]
ChannelsMyotonia congenita (MC) is a rare hereditary muscle disease caused by variants in the CLCN1 gene. Currently, the correlation of phenotype-genotype is still uncertain between dominant-type Thomsen (TMC) and recessive-type Becker (BMC).

A novel mutation in CLCN1 associated with feline myotonia congenita. [PDF]
PLoS ONE, 2014 Myotonia congenita (MC) is a skeletal muscle channelopathy characterized by inability of the muscle to relax following voluntary contraction. Worldwide population prevalence in humans is 1:100,000.

Biophysical and structural insights into the SCN4A E452K variant linked to myotonia and paramyotonia congenita [PDF]
Scientific ReportsMyotonia and paramyotonia congenita (PC) are rare neuromuscular disorders characterized by muscle stiffness that intensifies in cold environments. These disorders are associated with variants in the SCN4A gene, that encodes the alpha subunit of the ...

Becker congenital myotonia in black African with molecular findings
Egyptian Journal of Medical Human Genetics, 2022 Background Congenital myotonia is a congenital disorder that affects skeletal muscles with myotonia. Affected muscles show stiffness and pain sometimes. The two major types of myotonia congenita are known as Thomsen disease and Becker disease.

The Clinical, Myopathological, and Genetic Analysis of 20 Patients With Non-dystrophic Myotonia
Frontiers in Neurology, 2022 IntroductionNon-dystrophic myotonias (NDMs) are skeletal muscle ion channelopathies caused by CLCN1 or SCN4A mutations. This study aimed to describe the clinical, myopathological, and genetic analysis of NDM in a large Chinese cohort.MethodsWe reviewed ...
