Несмотря на то, что с момента проведения конгресса прошло некоторое время, освещенные его участниками проблемы, остаются актуальными в настоящее время и определяют направление современных исследований. Было сформировано представление о молекулярных и клеточных механизмах синдрома Ретта и ряда редких генетических/ геномных заболеваний. В статье представлен ряд отечественных разработок, полученных в области изучения синдрома Ретта и других редких заболеваний. Дана информация по редким болезням, ассоциированным с фенотипом, подобным синдрому Ретта, или с мутациями/вариациями числа копий последовательности гена MECP2. Выявленные хромосомные (геномные) нарушения/заболевания рассмотрены в контексте редких болезней. Данный подход к анализу результатов по изучению синдрома Ретта является новым в мировой исследовательской практике. Приведенная информация будет полезна специалистам в области редких генетических заболеваний, ученым и клиницистам, изучающим синдром Ретта, а также врачам (педиатрам, генетикам, неврологам, психиатрам), которые наблюдают этих больных в клинической практике.</p></abstract><trans-abstract xml:lang="en"><p>This review presents the theoretical, practical and geographical aspects of Rett syndrome and other rare diseases, according to the data of the last VIII International Congress in Russia, and the main publications on Rett syndrome. The issues highlighted by the participants remain relevant and determine the direction of modern studies. The presentations made at the symposium helped to form a global concept of the molecular and cellular mechanisms of Rett syndrome and a number of rare genetic/genomic diseases. The article presents a number of domestic findings in the field of Rett syndrome and other rare diseases. The authors also present information on rare diseases associated with the Rett-like-phenotype or with mutations/variations of the MECP2 gene sequence copies. The authors consider the identified chromosomal (genomic) disorders / diseases in the context of rare diseases. This approach to the Rett syndrome studies analysis is quite new in the world research practice. We hope this review to become valuable not only for specialists in the field of rare genetic diseases, but also for the scientists and clinicians studying Rett syndrome and for physicians (pediatricians, geneticists, neurologists, psychiatrists) meeting these patients in their practice.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>синдром Ретта</kwd><kwd>ген MECP2</kwd><kwd>хромосома Х</kwd><kwd>микроделеции участка Xq28</kwd><kwd>редкие (орфанные) заболевания</kwd><kwd>трансляционная медицина</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Rett syndrome</kwd><kwd>MECP2 gene</kwd><kwd>chromosome Х</kwd><kwd>Xq28 microdeletions</kwd><kwd>rare (orphan) diseases</kwd><kwd>translational medicine</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">Iourov I.Y., Vorsanova S.G., Yurov Y.B., Bertrand T.
