В статье представлен редкий клинический случай синдрома Коккейна типа II у ребёнка с подтверждённой мутацией в гене ERCC6 и тяжёлым течением заболевания. Манифестация симптомов отмечена в неонатальном периоде, в дальнейшем развились выраженный неврологический дефицит, сенсорная глухота, офтальмологические нарушения, эпилептический синдром и стойкая гипотрофия. Особенностью наблюдения является длительная продолжительность жизни (до 17 лет) на фоне крайне неблагоприятного прогноза, характерного для СК типа II. Диагноз был верифицирован молекулярно-генетически, нейровизуализация выявила характерные изменения головного мозга. Лечение носило поддерживающий характер и включало мультидисциплинарный подход: нутритивную, симптоматическую, противосудорожную и паллиативную терапию. Состояние ребёнка оставалось стабильно тяжёлым, требующим постоянного медицинского наблюдения. Описанный случай подчёркивает важность ранней диагностики, мультидисциплинарного ведения и настороженности клиницистов при ведении редких нейродегенеративных заболеваний в педиатрии.</p></abstract><trans-abstract xml:lang="en"><p>Cockayne syndrome (CS) is a rare autosomal recessive neurodegenerative disorder associated with impaired DNA repair, developmental delay, and multisystem involvement. This article presents a rare clinical case of type II CS in a child with a confirmed ERCC6 gene mutation and a severe disease course. Symptoms manifested in the neonatal period and progressed with profound neurological deficits, sensorineural hearing loss, ophthalmologic disorders, epileptic syndrome, and persistent malnutrition. A distinctive feature of this case is the unusually long survival (up to 17 years), which is exceptional for CS type II, typically associated with a poor prognosis. The diagnosis was confirmed by molecular genetic testing, and neuroimaging revealed characteristic brain abnormalities. The patient received supportive care based on a multidisciplinary approach, including nutritional, symptomatic, antiepileptic, and palliative treatment. The condition remained stably severe and required continuous medical supervision. This case emphasizes the importance of early diagnosis, ongoing multidisciplinary management, and clinical vigilance in children with rare neurodegenerative disorders.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Коккейна</kwd><kwd>нейродегенерация</kwd><kwd>нарушение репарации ДНК</kwd><kwd>мутация ERCC6</kwd><kwd>тип II</kwd><kwd>мультисистемная патология</kwd><kwd>прогероподобный синдром</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Cockayne syndrome</kwd><kwd>neurodegeneration</kwd><kwd>DNA repair disorder</kwd><kwd>ERCC6 mutation</kwd><kwd>type II</kwd><kwd>multisystem pathology</kwd><kwd>progeroid 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">Hatch M.K., Donnelly C., Prasun P. et al.
