В обоих случаях хромосомный дисбаланс в виде дупликации инсертированного района является следствием мейотической сегрегации инсерции у отцов-носителей перестройки. Случай 1 характеризуется несбалансированной интерхромосомной инсерцией у пациента, обследованного по поводу задержки темпов психомоторного развития, судорог неизвестной этиологии и аномального фенотипа. В результате комплексного обследования пациента и его родителей установлен следующий кариотип: 46,XY,der(2)ins(2;7)(q35;q31.33q34)pat. Случай 2 представлен несбалансированной интрахромосомной инсерцией у пациента с неонатальными судорогами. Стандартное цитогенетическое и молекулярно-цитогенетическое обследование пациента и его родителей позволили определить кариотип пациента: 46,XY,rес(2)dup(2q)inv ins(2)(р11.2q23.3q31)pat. Носительство инсерций характеризуется высоким репродуктивным риском, поэтому очень важным является идентификация и характеристика данной хромосомной перестройки. Современные высокотехнологичные молекулярные методы исследования позволяют значительно расширить диагностические возможности выявления геномного дисбаланса, но при этом не позволяют установить, в каком именно месте генома располагается дополнительный материал. FISH-анализ помогает не только подтвердить наличие дуплицированного участка, но и идентифицировать его локализацию. Только комплексный подход, заключающийся в сочетании стандартного цитогенетического исследования кариотипа с использованием молекулярно-генетических и молекулярно-цитогенетических методов, позволяет установить природу хромосомной перестройки, повысить качество медико-генетического консультирования семьи для оценки прогноза потомства и определить тактику пренатальной или предимплантационной диагностики.</p></abstract><trans-abstract xml:lang="en"><p>We report two familial cases of insertional translocations with chromosomе 2. Both abnormalities were derived from fathers having a balanced insertion. In case 1 patient was referred for evaluation because of developmental delay, seizures of unknown etiology and slight dysmorphic features showed a normal karyotype. Сomplex approach to diagnosis of the proband’s and his family allowed to determine karyotype as 46,XY,der(2)ins(2;7)(q35;q31.33q34)pat. In case 2 patient with neonatal seizures was referred for evaluation. Combined with the conventional cytogenetic studies and FISH analyses proband’s karyotype was determined as 46,XY,rес(2)dup(2q)inv ins(2)(р11.2q23.3q31)pat. In both this cases only complex approach such as CMA, FISH and conventional cytogenetics allows to perform a complete quality diagnosis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>интрахромосомные инсерции</kwd><kwd>интерхромосомные инсерции</kwd><kwd>стандартное цитогенетическое исследование</kwd><kwd>хромосомный микроматричный анализ</kwd><kwd>флуоресцентная in situ гибридизация</kwd><kwd>interchromosomal insertional translocations</kwd><kwd>intrachromosomal insertional translocations</kwd><kwd>conventional cytogenetic studies</kwd><kwd>chromosomal microarray</kwd><kwd>fluorescence in situ hybridization</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">Kang SHL, Show C.
