Abstract

A variety of inherited human disorders affecting skeletal muscle contraction, heart rhythm, and nervous system function have been traced to mutations in genes encoding voltage-gated sodium channels.Clinical severity among these conditions ranges from mild or even latent disease to life-threatening or incapacitating conditions.The sodium channelopathies were among the first recognized ion channel diseases and continue to attract widespread clinical and scientific interest.An expanding knowledge base has substantially advanced our understanding of structurefunction and genotype-phenotype relationships for voltage-gated sodium channels and provided new insights into the pathophysiological basis for common diseases such as cardiac arrhythmias and epilepsy.Nonstandard abbreviations used: GEFS+, generalized epilepsy with febrile seizures plus; ICEGTC, intractable childhood epilepsy with frequent generalized tonic-clonic seizures; LQTS, long QT syndrome; NaVCh, voltage-gated sodium channel; SIDS, sudden infant death syndrome; SMEB, borderline severe myoclonic epilepsy of infancy; SMEI, severe myoclonic epilepsy of infancy; SUDS, sudden unexplained death syndrome.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
