To develop a method for determining the maternal or paternal origin of chromosomal aneuploidies in embryos by performing STR analysis for patients who undergo assisted reproductive technologies (ART) programs. Materials and methods. The development of the method was carried out using biopsy material of the trophectoderm in embryos of 58 couples of patients (116 persons). Preimplantation genetic testing for aneuploidy (PGT-A) was performed using high-throughput sequencing. Determination of the origin of aneuploidy was performed by fragment analysis of STR markers. Results. After After PGT-A, aneuploidy was detected in 67 embryos (41%); euploid embryos were 65 (40%); mosaic forms were found in 28 (17%) embryos. Primers have been developed for the analysis of chromosomes 1, 3, 4. Development of primers for analysis of 1, 3, 4, 5, 6, 7, 9, 11, 12, 13, 14, 15, 16, 19, 22 and X chromosomes was performed. The analysis of chromosome 16 (n = 7 embryos), chromosome 19 (n = 5 embryos) and chromosome 22 (n = 8 embryos) showed that this approach can be used to identify both maternal and paternal origin of aneuploidy. Conclusion. A technological possibility of carrying out STR fragment analysis with purpose of genotyping of embryos using various products of whole genome amplification was shown. It makes possible to carry out PGT-A and PGT-M together with embryo genotyping without the need for repeated biopsies. The study parental contribution to the development of embryonic aneuploidy in future will allow to choose the most optimal tactics for managing patients with repeated unsuccessful attempts of ART and past miscarriages.</p></abstract><trans-abstract xml:lang="ru"><p>Цель. Разработать метод определения материнского или отцовского происхождения хромосомных анеуплоидий эмбриона с помощью STR-анализа у пациентов программ вспомогательных репродуктивных технологий (ВРТ). Материалы и методы. Разработка велась с использованием материала биопсии трофэктодермы эмбрионов 58 пар пациентов (116 человек). Предимплантационное генетическое тестирование на анеуплоидии (ПГТ-А) и моногенные заболевания (ПГТ-М) осуществляли с помощью высокопроизводительного секвенирования. Определение происхождения анеуплоидий проводили фрагментным анализом STR-маркеров. Результаты. После ПГТ-А анеуплоидии были выявлены у 67 эмбрионов (41%); эуплоидными были 65 (40%); мозаичные формы были обнаружены у 28 (17%) эмбрионов. Были разработаны праймеры для анализа хромосом 1, 3, 4, 5, 6, 7, 9, 11, 12, 13, 14, 15, 16, 19, 22 и X. Проведенный анализ (16-я хромосома (n=7 эмбрионов), 19-я хромосома (n=5 эмбрионов) и 22-я хромосома (n=8 эмбрионов)) показал, что с помощью данного подхода можно идентифицировать анеуплоидии как материнского, так и отцовского происхождения. Заключение. Показана принципиальная технологическая возможность проведения фрагментного STR-анализа с целью генотипирования эмбрионов с использованием различных продуктов полногеномной амплификации. Это позволяет проводить ПГТ-А и ПГТ-М совместно с генотипированием эмбрионов без необходимости повторных биопсий. Изучение влияния родительского вклада в развитие анеуплоидий эмбрионов в будущем позволит выбрать оптимальную тактику ведения пациентов с неоднократными неудачными попытками ВРТ и невынашиванием беременности в анамнезе.</p></trans-abstract><kwd-group xml:lang="en"><kwd>assisted reproductive technologies</kwd><kwd>embryo</kwd><kwd>PGT-A</kwd><kwd>PGT-M</kwd><kwd>chromosomal abnormalities</kwd><kwd>aneuploidy</kwd><kwd>fragment analysis</kwd><kwd>genotyping</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>вспомогательные репродуктивные технологии</kwd><kwd>эмбрион</kwd><kwd>ПГТ-А</kwd><kwd>ПГТ-М</kwd><kwd>хромосомные аномалии</kwd><kwd>анеуплоидии</kwd><kwd>фрагментный анализ</kwd><kwd>генотипирование</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Faramarzi A., Khalili M.A., Ashourzadeh S.
