However, at least 100 thousand cases of repeated pregnancy losses occur annually in the world, in which cytogenetic methods determine the chromosome euploid set in the abortive material. One of the causes of miscarriage is probably the loss of function of certain genes. It is assumed that the detection of genetic factors determining the etiology of pregnancy loss can help to develop personalized methods of diagnosis and preconception care in cases where the classical approach with chromosomal analysis is insufficient.</p> <p><bold>Aims </bold>— to analyze the experience of genetic testing of euploid embryos and identify the most significant genetic variants in miscarriage.</p> <p><bold>Methods.</bold> A search was conducted for sources of scientific literature in the PubMed and RSCI (elibrary) databases. The search for full-text articles was carried out on the websites of journals and using the ResearchGate database. The review included articles published in peer-reviewed scientific publications in the period from 2013 to 2023.</p> <p><bold>Results.</bold> Studies conducted on animals and analysis of human embryos during miscarriage have revealed a list of genes which loss of function may be associated with embryolethality. Analyzing the data of the scientific literature, we concluded that a number of genes potentially related to miscarriage can lead to various diseases in the postnatal period.</p> <p><bold>Conclusions. </bold>Scientific research aimed at finding monogenic causes of miscarriage is of great scientific and practical importance, since it can contribute to improving the algorithm of examination and pre-conception preparation of married couples with a history of pregnancy loss.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Хромосомные аномалии эмбриона — самая частая причина невынашивания беременности. Однако в мире ежегодно происходит не менее 100 тыс. случаев повторных потерь беременности, при которых цитогенетические методы определяют в абортивном материале эуплоидный хромосомный набор. Одной из причин таких потерь, вероятно, является утрата функции определенных генов. Предполагается, что обнаружение генетических факторов, определяющих этиологию потери беременности, может помочь разработать персонализированные методы диагностики и преконцепционной подготовки в тех случаях, когда классический подход с хромосомным анализом оказывается недостаточным.</p> <p><bold>Цель исследования </bold>—<bold> </bold>проанализировать накопленный опыт генетического тестирования эуплоидных эмбрионов и выделить наиболее значимые генетические варианты при невынашивании беременности.</p> <p><bold>Методы. </bold>Был проведен поиск источников научной литературы в базах PubMed и РИНЦ (elibrary). Поиск полнотекстовых статей проведен на сайтах журналов и с помощью базы ResearchGate. В обзор были включены работы, опубликованные в рецензируемых научных изданиях с 2013 по 2023 г.</p> <p><bold>Результаты. </bold>Исследования, проведенные на животных, и анализ эмбрионов человека при невынашивании беременности позволили выявить перечень генов, утрата функций которых может быть ассоциирована с эмбриональной летальностью. Анализируя данные научной литературы, мы пришли к выводу, что ряд генов, потенциально имеющих отношение к неразвивающейся беременности, может приводить и к различным заболеваниям в постнатальном периоде у детей.</p> <p><bold>Заключение.</bold> Научные исследования, направленные на поиск моногенных причин невынашивания беременности, имеют большую научную и практическую значимость, поскольку могут способствовать совершенствованию алгоритма обследования и преконцепционной подготовки супружеских пар, имеющих потери беременности в анамнезе.</p></trans-abstract><kwd-group xml:lang="en"><kwd>miscarriage</kwd><kwd>clinical sequencing of exome</kwd><kwd>chromosomal micromatrix analysis</kwd><kwd>preimplantation genetic testing</kwd><kwd>embryo genome sequencing</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>невынашивание беременности</kwd><kwd>клиническое секвенирование экзома</kwd><kwd>хромосомный микроматричный анализ</kwd><kwd>преимплантационное генетическое тестирование</kwd><kwd>секвенирование генома эмбриона</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Feichtinger M, Wallner E, Hartmann B, et al.
