The severity of epilepsy is related to the size of the mutation.</p><p>Objective: to study the clinical and electroencephalographic picture of the disease.</p><p>We have analyzed 3 cases (male patients from 2 to 6 years old), including anamnesis of life and disease, electroencephalography data in dynamics and genetic analysis data.</p><p>All three patients are united by a combination of epilepsy, mental retardation and cerebral palsy-like movement disorders. The epilepsy manifestations varied from severe with absolutely pharmacoresistant epileptic spasms (cases 1 and 2) to mild course with febrile seizures only (case 3). This is probably due to the presence of a shorter mutation in patient 3. Cases 1 and 2 had epileptic encephalopathy, epilepsy with continuing epileptiform discharges on the EEG and a gross delay in speech and mental development. These patients could not speak and not understand the speech addressed, do not follow instructions. Patient 3’ self-care and play activities are developed by age, speech understanding is fully formed, but there is a complete absence of expressive speech.</p><p>1p36 deletion syndrome is a developmental and epileptic encephalopathy.  </p></abstract><trans-abstract xml:lang="ru"><p>Синдром делеции 1р36 (OMIM: 607872) – аутосомно-доминантное заболевание, вызванное терминальной делецией короткого плеча хромосомы 1 и характеризующееся специфическим черепно-лицевым дисморфизмом, задержкой психоречевого развития и эпилептическими приступами. Степень тяжести эпилепсии связана с величиной мутации.</p><p>Цель работы – изучить клинико-электроэнцефалографическую картину заболевания.</p><p>Проанализированы 3 собственных наблюдения (пациенты мужского пола в возрасте от 2 до 6 лет), включающие анамнез жизни и заболевания, данные генетического анализа и электроэнцефалографии в динамике.</p><p>Всех 3 пациентов объединяет сочетание эпилепсии, задержки психического развития и двигательных нарушений по типу детского церебрального паралича. Тяжесть проявлений эпилепсии варьирует от тяжелой степени с абсолютно фармакорезистентными эпилептическими спазмами (случаи 1 и 2) до легкого течения, когда приступы развиваются только на фоне лихорадки при острой респираторной вирусной инфекции (не при каждом случае возникшего у пациента лихорадочного заболевания). Вероятно, это связано с наличием меньшей по протяженности мутации у пациента 3. В 2 случаях на фоне эпилептической энцефалопатии, резистентной к лечению эпилепсии и продолжающихся эпилептиформных разрядов на электроэнцефалограмме отмечается грубая задержка психоречевого развития. Эти пациенты не говорят, не понимают обращенную речь, не выполняют инструкции. У 1 пациента самообслуживание и игровая деятельность развиты по возрасту, понимание речи сформировано в полном объеме, но отмечается полное отсутствие экспрессивной речи.</p><p>Синдром делеции 1р36 относится к группе энцефалопатии развития и эпилептической.</p></trans-abstract><kwd-group xml:lang="en"><kwd>chromosome 1p36 deletion syndrome</kwd><kwd>epileptic encephalopathy</kwd><kwd>epilepsy</kwd><kwd>developmental delay</kwd><kwd>electroencephalography</kwd><kwd>video-electroencephalography monitoring</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>микроделеционный синдром короткого плеча 1 хромосомы 1p36</kwd><kwd>эпилептическая энцефалопатия</kwd><kwd>эпилепсия</kwd><kwd>энцефалопатия развития</kwd><kwd>электроэнцефалография</kwd><kwd>видеоэлектроэнцефалографический мониторинг</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">1.
