There is an increased risk of SUDEP in genetic epileptic encephalopathies (EE), partly because those syndromes are associated with mutations in the “neurocardiac” genes, which have been implicated in both epilepsy and cardiac arrhythmias. In these clinical conditions, functions of ion selective channels (sodium, potassium and etc.) are affected; for example, in children with Dravet syndrome, the risk of SUDEP is 40 times higher than that in children with common epilepsy syndromes. In a murine model of SCN1A epilepsy, a prolongation of QT interval coincided with a seizure; in addition, an excessive excitability of cultured cardiomyocytes was demonstrated. A high risk of SUDEP is characteristic for EE caused by mutation in the SCN8A gene. Other prognostic biomarkers of SUDEP may include mutations in sodium channel genes, such as SCN4A, SCN10A, and SCN11A. Our knowledge about SUDEP associated with potassium channel dysfunctions is still very limited. There are likely some mutations in other genes, that can modify (increase or decrease) the risk of SUDEP in EE. If patients with genetic EE are indeed at a high risk for SUDEP, they must be followed up by cardiologists alongside with neurologists. Provided this hypothesis is proved, any newly diagnosed arrhythmia should be carefully monitored and treated (with medications and/or interventions), in order to improve the survival rate in genetic EE.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром внезапной смерти при эпилепсии (SUDEP – сокр. от англ. Sudden unexpected death in epilepsy) является одной из основных причин летальности при этом заболевании. Особенно высок риск SUDEP при генетических эпилептических энцефалопатиях (ЭЭ), что объясняется существованием «нейрокардиальных» генов, одновременно вызывающих и эпилепсию, и жизнеугрожающие нарушения сердечного ритма. Наиболее вероятно, что жизнеугрожающие аритмии развиваются в критический момент эпилептического приступа. Чаще всего «нейрокардиальные» гены ответственны за функции ионных каналов – натриевых, калиевых и др. Так, при синдроме Драве (патология натриевых каналов), риск SUDEP в 40 раз превышает таковой в общей популяции детей с эпилепсией. В экспериментальных работах у мышей с мутацией SCN1A доказано удлинение интервала QT в момент эпилептического приступа, а также повышенная электрическая возбудимость кардимиоцитов. Повышенный риск SUDEP характерен для ЭЭ, вызванных мутацией в гене SCN8A. Потенциально биомаркерами SUDEP могут быть мутации и в других генах натриевых каналов (SCN4A, SCN10A, SCN11A). Менее изучен риск SUDEP при ЭЭ, обусловленных мутациями калиевых каналов. Возможно, что при генетических каналопатиях существуют дополнительные мутации в других генах, которые могут увеличивать или уменьшать риск SUDEP. Если действительно пациенты с генетическими эпилептическими энцефалопатиями относятся к группе риска по нарушениям сердечного ритма, как причине SUDEP, то они должны тщательно обследоваться и наблюдаться не только у неврологов, но и у кардиологов. Выявленные у них в межприступном периоде нарушения ритма сердца должны мониторироваться и, при необходимости, лечиться медикаментозно или интервенционно. Вероятно, что такое наблюдение и своевременная терапия могут существенно повлиять на прогноз и выживание пациентов с генетическими эпилептическими энцефалопатиями.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром внезапной смерти при эпилепсии</kwd><kwd>генетические эпилептические энцефалопатии</kwd><kwd>нейрокардиальные гены</kwd><kwd>каналопатии</kwd><kwd>аритмии</kwd><kwd>синдром Драве</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sudden unexpected death in epilepsy</kwd><kwd>SUDEP</kwd><kwd>genetic epileptic encephalopathies</kwd><kwd>“neurocardiac” genes</kwd><kwd>arrhythmias</kwd><kwd>Dravet syndrome</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jones L.
