По результатам стандартного цитогенетического анализа (СЦА) у супругов установлен нормальный кариотип. Изучение кариотипов эмбрионов при преимплантационном генетическом тестировании выявило наличие у них частичных анеуплоидий по терминальным регионам хромосом. Выполнено молекулярно-цитогенетическое исследование с использованием специфических ДНК-проб на кандидатные субтеломерные области хромосом. У женщин выявлено наличие сбалансированных транслокаций: в первом случае между терминальными регионами хромосом 1 и 10, во втором − между хромосомами 7 и 17.</p></abstract><trans-abstract xml:lang="en"><p>An examination of two families with reproductive dysfunction was conducted. In both families, the spouses had a normal karyotype based on the results of cytogenetic analysis. The study of the karyotypes of embryos during preimplantation genetic testing revealed the presence of partial aneuploidies in the terminal regions of chromosomes. A molecular cytogenetic analysis was performed using specific DNA probes for candidate subtelomeric regions of chromosomes. The women were found to have a balanced translocation: in the first case, between the terminal regions of chromosomes 1 and 10, and in the second case, between chromosomes 7 and 17.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>бесплодие</kwd><kwd>ПГТ-А</kwd><kwd>флуоресцентная гибридизация in situ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>infertility</kwd><kwd>PGT-A</kwd><kwd>fluorescence in situ hybridization</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовом обеспечении НИИ медицинской генетики ФГБНУ «Томский НИМЦ РАН».</funding-statement><funding-statement xml:lang="en">The study was carried out with financial support from the Research Institute of Medical Genetics of the Tomsk National Research Medical Center of the Russian Academy of Sciences.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Rooney D.E., Czepulkowski B.H, Human Cytogenetics: A Practical Approach.
