При описании клинического случая (девочка 4 лет с подтвержденным диагнозом эпилептической энцефалопатии SYNGAP1) подробно проанализированы анамнез заболевания, генеалогический анамнез, данные неврологического, нейропсихологического и речевого статусов, результаты генетического, электроэнцефалографического и нейровизуализационного (магнитно-резонансная томография – МРТ) обследований. Результаты обзора показывают, что ведущими симптомами заболевания, как правило, служат эпилепсия, расстройства аутистического спектра, отсутствие фразовой речи и умственная отсталость. К наиболее часто встречающимся эпилептическим приступам относятся атипичные абсансы, миоклонические, атонические приступы, миоклония век с абсансами, на электроэнцефалограмме: замедление в затылочных областях, диффузные продолженные комплексы «пик-, полипик-медленная волна». Патогномоничные нейровизуализационные изменения головного мозга обычно отсутствуют. Наиболее эффективны в контроле эпилептических припадков вальпроевая кислота, леветирацетам, этосуксимид. Учитывая редкость синдрома, авторы представили детальное описание клинического случая из собственной практики.</p><p>Заключение. Эпилептическая энцефалопатия SYNGAP1 имеет особую клиническую картину, включающую специфические изменения на ЭЭГ и определенный набор эпилептических приступов. Диагностический алгоритм для детей с эпилептической энцефалопатией, аутизмом, задержкой психоречевого развития должен содержать видео-электроэнцефалографический мониторинг с включением сна, а также поиск редких генетических синдромов, при необходимости с помощью секвенирования нового поколения, что позволяет рано выявить заболевание и выстроить адекватный план терапии.</p></abstract><trans-abstract xml:lang="en"><p>The paper analyzes data from scientific publications and presents a clinical case study of a rare genetic epileptic encephalopathy caused by a mutation in the SYNGAP1 gene. The case study focuses on a 4-year-old girl who has been diagnosed with epileptic encephalopathy due to the mutation. The paper describes the anamnesis of the child’s illness, including family history, neurological, neuropsychological, and speech assessments, as well as the results of genetic testing, electroencephalography, and magnetic resonance imaging (MRI). The findings indicate that the main symptoms of the condition are typically epilepsy, autism spectrum disorder, difficulty with phrasal speech, and mental retardation. Common types of seizures include atypical absence seizures, myoclonic seizures, atonic seizures, and eyelid myoclonia with absences. On the electroencephalogram, there is a slowdown in occipital activity and diffuse, prolonged «peak-polypic-slow-wave» complexes. Pathognomonic neuroimaging changes in the brain are typically absent. Valproic acid, levetiracetam, and ethosuximide have been shown to be the most effective treatments for controlling epileptic seizures. Due to the rarity of this syndrome, the authors have provided a detailed clinical case report from their practice.</p><p>Conclusion. SYNGAP1-related epileptic encephalopathy has a specific clinical presentation, including characteristic EEG findings and a particular pattern of seizures. The diagnostic approach for children with this condition, autism spectrum disorder, and delayed language development should include video electroencephalography with sleep deprivation, as well as genetic testing if necessary, using next-generation sequencing, to ensure early detection and appropriate treatment planning.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>эпилептическая энцефалопатия SYNGAP1</kwd><kwd>аутизм</kwd><kwd>умственная отсталость</kwd><kwd>генетическая эпилепсия</kwd><kwd>электроэнцефалография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>SYNGAP1-related epileptic encephalopathy</kwd><kwd>autism</kwd><kwd>mental retardation</kwd><kwd>genetic epilepsy</kwd><kwd>electroencephalography</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">Vlaskamp D.R.M., Shaw B.J., Burgess R., Mei D., Montomoli M., Xie H. et al.
