Interestingly, a British pediatric cohort observed that limb myotonia, strabismus, and respiratory symptoms are common among children with sodium channelopathy
Arrhythmic disorders that are heritable, such as an ion channelopathy

18) In cases of superimposed hereditary or genetic channelopathy
variants, such as HPP (hyperkalemic periodic paralysis) where deficient potassium channels are dysfunctional and potassium levels rise.
Congenital myotonia is a genetic channelopathy
that affects skeletal muscles.
There are two hypotheses: cerebellar and intracortical dysfunction could result from a channelopathy
(migraine comorbidity supported this theory) or decreased cortical inhibition may be caused by dysfunction of the cerebello-thalamo-cortical loop as a result of primary cerebellar pathology (12).
