Одной из генетических причин интеллектуальных расстройств (ИР) являются вариации числа копий участков ДНК (CNV). Несмотря на то, что для некоторых вариаций показана связь с известными синдромами, большая их часть является редкими. Как правило, CNVs затрагивают протяженные области, включающие несколько генов. В ряде случаев мутации касаются единичных генов, что дает возможность связать изменение их дозы с наблюдаемыми клиническими аномалиями у пациента. Цель. Настоящая работа направлена на характеристику структурной вариабельности генома человека при ИР и картирование кандидатных генов. Материалы и методы. На микрочипах 44K и 60K (Agilent Technologies) проведено молекулярное кариотипирование 136 детей в возрасте от 3 до 17 лет с задержкой развития и ИР. Результаты. У 87 чел. (64%) кариотип оказался условно нормальным. Молекулярный диагноз поставлен 18 пациентам (13%). У 31 ребенка (23%) выявлены потенциально патогенные мутации. Для синдромов микроделеций 15q24 и 16p11.2 выделены минимальные регионы микроделеции, в которых идентифицированы гены-кандидаты. Впервые обнаружены реципрокные микроделеция и мипродупликация единственного гена CNTN6 , экспрессируюшегося в мозге и ставшего кандидатным для ИР. Выводы. aCGH-анализ является эффективным методом генетической диагностики, который при обнаружении моногенных мутаций является информативным для идентификации новых генов-кандидатов ИР.</p></abstract><trans-abstract xml:lang="en"><p>Introduction. One of the genetic causes of intellectual disabilities (ID) is copy number variation (CNV). Despite the fact that for some variations an association with known syndromes has been shown, most of them are rare. Usually CNVs involve extended regions, including several genes. In some cases CNVs include single genes, what enables to directly link a change of their dose with clinical abnormalities observed in a patient. Aim. This work aims to characterize structural genomic variation in patients with ID and map candidate genes. Materials and methods. Using Agilent 44K and 60K arrays the molecular karyotyping for 136 children of 3-17 years old with developmental delay, ID and dysmorphic features was performed. Results. Eighty-seven individuals (64%) had normal karyotype or benign CNVs. Known microdeletion or microduplication syndromes were identified in 18 patients (13%). In the remaining 31 children (23%) potentially pathogenic mutations were found. For 15q24 and 16p11.2 microdeletion syndromes, diagnosed in two and three patients, respectively, using the literature data the minimal deleted regions and candidate genes within them were identified. In two families the reciprocal microdeletion and miproduplication of single CNTN6 gene were found. This gene is expressed in the brain and, therefore, is a candidate for ID. Conclusions. aCGH-analysis is an effective method for genetic diagnosis, which, when mutations in single genes are detected, allows identification of new candidate genes for intellectual disability.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>недифференцированные интеллектуальные расстройства</kwd><kwd>матричная сравнительная геномная гибридизация</kwd><kwd>вариации числа копий участков ДНК</kwd><kwd>кандидатные гены</kwd><kwd>undifferentiated intellectual disability</kwd><kwd>array comparative genomic hybridization</kwd><kwd>DNA copy number variation</kwd><kwd>candidate genes</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">Gilissen C, Hehir-Kwa JY, Thung DT et al.
