Частота встречаемости составляет 5,1 : 1 000 000. Для новорождённых с данным синдромом характерны мышечная гипотония, в связи с чем дети испытывают затруднение при дыхании и проблемы с кормлением; черепно-лицевой дисморфизм: «грубое» лицо — высокий выступающий лоб, косые глазные щели с эпикантом, гипертелоризм, широкий и уплощённый нос с вывернутыми ноздрями, низко посаженные и диспластичные уши, микрогнатия, широкий рот с выворотом нижней губы, тонкая верхняя губа в форме «лука Купидона». У большинства детей встречаются высокая линия роста волос, двусторонняя лобно-височная алопеция, редкие брови или ресницы, участки гипопигментации в виде светлых пятен или полос. В неврологическом статусе чаще всего отмечается серьёзная задержка темпов речевого, моторного и интеллектуального развития, хотя описано и более «мягкое» течение болезни. Характерны специфические расстройства речи.</p><p>Для верификации диагноза необходимо исследование буккального эпителия или фибробластов с помощью FISH-анализа. Прогноз заболевания неблагоприятный. Его также усугубляет наличие глубокой интеллектуальной недостаточности и возможное развитие судорог. Специфического лечения пациентов не разработано. В зависимости от клинических проявлений лечение может включать хирургическую коррекцию выявленных врождённых нарушений. Одним из важных этапов ведения пациентов с таким диагнозом является работа с психологами и педагогами, способствующая поддержанию интеллектуального развития и социализации ребёнка.</p><p>В статье приведён клинический случай ведения ребёнка с синдромом Паллистера–Киллиана, а также современные взгляды на диагностику данного заболевания.</p><sec><title>Участие авторов</title><p>Участие авторов:Харитонова Н.А. — концепция и дизайн исследования, сбор и обработка материала, написание текста, редактирование;Басаргина М.А. — редактирование;Вавилова Н.В. — сбор и обработка материала;Увакина Е.В. — сбор и обработка материала;Нестерович М.И. — сбор и обработка материала.Все соавторы — утверждение окончательного варианта статьи, ответственность за целостность всех частей статьи.</p></sec><sec><title>Финансирование</title><p>Финансирование.

The frequency of occurrence is 5.1:1,000,000. Newborns with this syndrome are characterized by muscular hypotension, which causes children to experience breathing difficulty and feeding problems, craniofacial dysmorphic disorder: a “rough” face — a high protruding forehead, oblique eye slits with epicanthus, hypertelorism, a wide and flattened nose with turned-out nostrils, low-set and dysplastic ears, micrognathia, a wide mouth with an inverted lower lip, a thin upper lip in the shape of a Cupid’s bow. Most children have a high hairline, bilateral frontal-temporal alopecia, sparse eyebrows or eyelashes, and areas of hypopigmentation in the form of light spots or streaks. The neurological status most often shows a serious delay in the pace of speech, motor, and intellectual development, although a more “mild” course of the disease is described. Specific speech disorders are also characteristic.</p><p>To verify the diagnosis, the child needs to examine the buccal epithelium or fibroblasts using FISH analysis. The prognosis of the disease is unfavourable. It is also aggravated by the presence of profound intellectual disability and the possible development of seizures. Currently, no specific treatment for patients has been developed. Depending on the clinical manifestations, therapy may include surgical correction of the identified congenital disorders. One of the important stages of managing patients with such a diagnosis is working with psychologists and educators to support the intellectual development and socialization of the child.</p><p>The article presents a clinical case of managing a child with Pallister–Killian syndrome, as well as current views on the diagnosis of this disease.</p><sec><title>Contribution</title><p>Contribution:Kharitonova N.A. — concept and design of the study, collection and processing of material, writing the text, editing;Basargina M.A. — editing;Vavilova N.V. — collection and processing of material;Uvakina Ye.V. — collection and processing of material;Nesterovich M.I. — collection and processing of material.All authors — responsibility for the integrity of all parts of the manuscript and approval of its final version.</p></sec><sec><title>Acknowledgment</title><p>Acknowledgment.
