RYR1Ryanodine receptor 1Disease-causing germline mutation(s) inTolerante
FUNÇÃO

Cytosolic calcium-activated calcium channel that mediates the release of Ca(2+) from the sarcoplasmic reticulum into the cytosol and thereby plays a key role in triggering muscle contraction following depolarization of T-tubules (PubMed:11741831, PubMed:16163667, PubMed:18268335, PubMed:18650434, PubMed:26115329). Repeated very high-level exercise increases the open probability of the channel and leads to Ca(2+) leaking into the cytoplasm (PubMed:18268335). Can also mediate the release of Ca(2+)

Malignant hyperthermia 1

Autosomal dominant pharmacogenetic disorder of skeletal muscle and is one of the main causes of death due to anesthesia. In susceptible people, an MH episode can be triggered by all commonly used inhalational anesthetics such as halothane and by depolarizing muscle relaxants such as succinylcholine. The clinical features of the myopathy are hyperthermia, accelerated muscle metabolism, contractures, metabolic acidosis, tachycardia and death, if not treated with the postsynaptic muscle relaxant, dantrolene. Susceptibility to MH can be determined with the 'in vitro' contracture test (IVCT): observing the magnitude of contractures induced in strips of muscle tissue by caffeine alone and halothane alone. Patients with normal response are MH normal (MHN), those with abnormal response to caffeine alone or halothane alone are MH equivocal (MHE(C) and MHE(H) respectively).

KCNJ5G protein-activated inward rectifier potassium channel 4Candidate gene tested inTolerante
FUNÇÃO

Inward rectifier potassium channels are characterized by a greater tendency to allow potassium to flow into the cell rather than out of it. Their voltage dependence is regulated by the concentration of extracellular potassium; as external potassium is raised, the voltage range of the channel opening shifts to more positive voltages. The inward rectification is mainly due to the blockage of outward current by internal magnesium. Can be blocked by external barium. This potassium channel is control

FUNÇÃO

Pore-forming subunit of Nav1.4, a voltage-gated sodium (Nav) channel that directly mediates the depolarizing phase of action potentials in excitable membranes. Navs, also called VGSCs (voltage-gated sodium channels) or VDSCs (voltage-dependent sodium channels), operate by switching between closed and open conformations depending on the voltage difference across the membrane. In the open conformation they allow Na(+) ions to selectively pass through the pore, along their electrochemical gradient.

Paramyotonia congenita

An autosomal dominant channelopathy characterized by myotonia, increased by exposure to cold, intermittent flaccid paresis, not necessarily dependent on cold or myotonia, lability of serum potassium, non-progressive nature and lack of atrophy or hypertrophy of muscles. In some patients, myotonia is not increased by cold exposure (paramyotonia without cold paralysis). Patients may have a combination phenotype of PMC and HYPP.

Myotonia congenita, autosomal dominant

A non-dystrophic skeletal muscle disorder characterized by muscle stiffness and an inability of the muscle to relax after voluntary contraction. Most patients have symptom onset in the legs, which later progresses to the arms, neck, and facial muscles. Many patients show marked hypertrophy of the lower limb muscles. The autosomal dominant form (Thomsen disease) is less common and less severe than the autosomal recessive one (Becker disease). A milder form of autosomal dominant myotonia is characterized by isolated myotonia without muscle weakness, hypotrophy, or hypertrophy (myotonia levior).

FUNÇÃO

Pore-forming, alpha-1S subunit of the voltage-gated calcium channel that gives rise to L-type calcium currents in skeletal muscle. Calcium channels containing the alpha-1S subunit play an important role in excitation-contraction coupling in skeletal muscle via their interaction with RYR1, which triggers Ca(2+) release from the sarcoplasmic reticulum and ultimately results in muscle contraction. Long-lasting (L-type) calcium channels belong to the 'high-voltage activated' (HVA) group

The importance of comprehensive diagnostic work-up and genetic testing to reveal Andersen-Tawil syndrome-a case report.

European heart journal. Case reports2026 Feb

Este artigo enfatiza a importância de um diagnóstico completo e testes genéticos para a Síndrome de Andersen-Tawil (ATS), uma canalopatia rara que pode causar anomalias cardíacas graves (inclusive parada cardíaca), paralisia muscular e características dismórficas. Dada a apresentação clínica variável e desafiadora, o teste genético é crucial para a confirmação da ATS, mesmo em casos com sintomas inicialmente isolados ou de início tardio. Além disso, o artigo aborda a miotonia congênita como outra canalopatia muscular genética, caracterizada por rigidez e atraso no relaxamento muscular devido a mutações no gene CLCN1.

Myopathies in clinical care: a focus on treatable causes.

Journal of neural transmission (Vienna, Austria : 1996)2026 Feb 28

As miopatias, que causam fraqueza, fadiga ou dor muscular, frequentemente possuem causas tratáveis. Embora a maioria das miopatias adquiridas já responda a terapias, o avanço de tratamentos moleculares e genéticos oferece agora opções eficazes para algumas formas hereditárias antes sem cura. Este artigo é crucial para médicos e pacientes, pois enfatiza uma abordagem clínica para identificar e gerenciar essas condições, focando nas que têm tratamentos estabelecidos ou emergentes.

Epidemiological report and diagnostic approach used in the neuromuscular population of Liege, Belgium.

Orphanet journal of rare diseases2025 Aug 29

Este estudo sobre doenças neuromusculares (DNM) em Liege, Bélgica, revelou que as neuropatias e distrofias musculares são as condições mais comuns, com as canalopatias representando uma parte menor (2-6%) da população estudada. Para pacientes e médicos, é crucial notar que, embora o sequenciamento de nova geração (NGS) seja promissor, a maioria dos diagnósticos genéticos ainda é obtida por métodos tradicionais, devido aos altos custos e complexidade das tecnologias mais avançadas.

Novel SCN4A Variants Associated With Myalgic Myotonic Disorder or Paramyotonia.

European journal of neurology2025 May

Este estudo identificou cinco novas variantes do gene SCN4A, associadas a sintomas como dor muscular (mialgia), rigidez e cãibras, frequentemente induzidas por exercício ou frio. A maioria dos pacientes apresentou descargas miotônicas no exame de eletroneuromiografia (EMG), e testes funcionais confirmaram que a maioria dessas variantes são patogênicas, causando um "ganho de função" que leva aos sintomas. Para médicos e pacientes, esses achados expandem o conhecimento sobre as causas genéticas das canalopatias musculares. Sugere-se que essas novas variantes sejam consideradas em pacientes com paramiotonia ou mialgia e cãibras induzidas por exercício que apresentem miotonia no EMG.

TRPV4 neuromuscular disease registry highlights bulbar, skeletal and proximal limb manifestations.

Brain : a journal of neurology2025 Jan 07

As doenças neuromusculares relacionadas ao TRPV4, como algumas formas de CMT e atrofia muscular espinhal, são genéticas e causam principalmente fraqueza muscular, com destaque para dificuldades em andar, fraqueza nos membros (próximos), problemas nas cordas vocais e respiratórios (muitos necessitando de suporte), além de anormalidades esqueléticas. Este estudo detalha essas manifestações clínicas, que diferem de outras CMTs, e mostra que pacientes com início infantil da doença podem ter uma progressão de sintomas menos evidente. Há um promissor potencial terapêutico com inibidores de TRPV4, mas é essencial que futuros ensaios clínicos avaliem essa ampla gama de sintomas (motores, vocais e respiratórios) para garantir a eficácia do tratamento.
