The peculiarity of the disease was in the late manifestation of clinical symptoms (6 years old), when there was autistic behavior and regression in development, as well as rare stereotypical hand movements, with characteristic changes in the EEG as benign epileptiform patterns of childhood. In adolescence (12 years) there were episodes of hyperventilation and arrest breathing, deformation of the back, inappropriate laughter and screams. Was found mutation in the heterozygous state (s.674&gt;G / N) in the gene MECP2 (exons 1–4) by the method of direct automatic sequencing.</p></abstract><trans-abstract xml:lang="ru"><p>Представлено описание редкого клинического случая атипичной формы синдрома Ретта у девочки-подростка. Особенность заболевания заключалась в позднем дебюте клинических симптомов (в возрасте 6 лет), когда появились аутистическое поведение и регресс в развитии, а также редкие стереотипные движения руками, с характерными изменениями на электроэнцефалограмме в виде доброкачественных эпилептиформных паттернов детства. В подростковом возрасте (в 12 лет) возникли эпизоды гипервентиляции и задержки дыхания, деформация спины, неадекватный смех и пронзительные крики. Методом прямого автоматического секвенирования в гене MECP2 (экзоны 1–4) была выявлена мутация в гетерозиготном состоянии (вариант с.674&gt;G / N).</p></trans-abstract><kwd-group xml:lang="en"><kwd>atypical form of Rett syndrome</kwd><kwd>autistic regression</kwd><kwd>benign epileptiform patterns of childhood</kwd><kwd>sequencing method</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>атипичная форма синдрома Ретта</kwd><kwd>аутистический регресс</kwd><kwd>доброкачественные эпилептиформные паттерны детства</kwd><kwd>прямое автоматическое секвенирование</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.
