In the authors’ experience, PNKD episodes are frequently mistaken for seizures due to background epileptiform activity on EEG or co‐morbid epileptic seizures, which are also prevalent in KCNMA1‐linked channelopathy,2 despite the lack of confirmatory abnormalities on scalp EEG during the dyskinesias. The gene discussed is KCNMA1; the disease is channelopathy.
