Синдром Ангельмана обусловлен потерей участка 15q11.2–q13 хромосомы 15, полученной от матери, что ведет к нарушению экспрессии гена UBE3A.</p><sec><title>Цель исследования</title><p>Цель исследования. Анализ клинических проявлений у детей с синдромом Ангельмана для выделения рано манифестирующих и характерных клинических признаков.</p><p>Характеристика детей и методы исследования. В исследование включили 60 детей. Во всех случаях диагноз синдрома Ангельмана ставился по международным клиническим критериям и результатам генетического обследования. В работе использовались клинические, функциональные и молекулярно-генетические методы исследования.</p></sec><sec><title>Результаты</title><p>Результаты. У 80–100% детей встречались такие признаки, как задержка психического и моторного развития, отсутствие речи, аффективное поведение, атаксия, стереотипии рук, апраксия движений рук, страбизм, сиалорея. Эпилептические приступы наблюдались у 72% детей; у всех (независимо от наличия/отсутствия эпилепсии) был характерный для синдрома Ангельмана паттерн на электроэнцефалограмме. Дифференциальный диагноз проводился с генными/хромосомными синдромами, характеризующимися сходными клиническими признаками.</p></sec><sec><title>Заключение</title><p>Заключение. О возможном наличии у ребенка синдрома Ангельмана свидетельствует сочетание таких наиболее частых, ранних клинических симптомов, как трудности при кормлении, страбизм, нарушение мышечного тонуса, задержка моторного и психоречевого развития, аффективное поведение с частым смехом, расстройства сна.</p></sec></abstract><trans-abstract xml:lang="en"><p>Angelman syndrome is a genetic disorder characterized by mental retardation and severe speech delay, movement disorders and ataxia, dysmorphic features, and behavioral disorders. Angelman syndrome is caused by the loss of the 15q11.2-q13 region of chromosome 15 received from the mother, which leads to a violation of the expression of the UBE3A gene.</p><sec><title>Purpose</title><p>Purpose. To analyze clinical manifestations in children with Angelman syndrome to identify early-onset and characteristic clinical signs.</p><p>Characteristics of children and research methods. The study included 60 children. In all cases, Angelman syndrome was diagnosed on the basis of international clinical criteria and the results of genetic testing. The researchers used clinical, functional and molecular genetic research methods.</p></sec><sec><title>Results</title><p>Results. 80-100% of children demonstrated delayed mental and motor development, lack of speech, affective behavior, ataxia, hand stereotypes, apraxia of hand movements, strabismus, sialorrhea. 72% of children had epileptic seizures; all patients (regardless of the presence / absence of epilepsy) had a pattern characteristic of Angelman syndrome on the electroencephalogram. Differential diagnosis was based on the gene / chromosomal syndromes characterized by similar clinical signs.</p></sec><sec><title>Conclusion</title><p>Conclusion. The combination of such most frequent, early clinical symptoms as difficulties in feeding, strabismus, impaired muscle tone, delayed motor and psycho-speech development, affective behavior with frequent laughter, and sleep disorders may indicate Angelman syndrome in a child.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>дети</kwd><kwd>синдром Ангельмана</kwd><kwd>клинические проявления</kwd><kwd>ранняя диагностика</kwd><kwd>ген UBE3A</kwd><kwd>делеция 15q11.2–q13</kwd></kwd-group><kwd-group xml:lang="en"><kwd>children</kwd><kwd>Angelman syndrome</kwd><kwd>clinical manifestations</kwd><kwd>early diagnosis</kwd><kwd>UBE3A gene</kwd><kwd>15q11.2–q13 deletion</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">Debopam S.
