Стероидогенез играет важную роль в репродуктивном здоровье женщины. В стероидогенезе задействован ряд генов, полиморфизм которых может быть ассоциирован с НБ. Нами проанализированы последовательности генов CYP21A2, HSD3B2, CYP17A1, STAR, CYP11A1, POR методами NGS, ПЦР-ПДРФ и MLPA у 30 женщин с НБ в анамнезе и у 46 пациенток из группы контроля. Всего выявлено 142 варианта нуклеотидной последовательности, как в кодирующих, так и в некодирующих областях генов с разной степенью клинической значимости. Патогенные варианты идентифицированы в гене CYP21A2 у 30 % женщин с НБ и в 6,5 % случаях группы контроля. В гене POR идентифицирован один миссенс вариант rs17853284 с возможным неблагоприятным эффектом. Гетерозиготное носительство в генах стероидогенеза, особенно в гене CYP21A2, требует более пристального изучения как предиктор осложнений течения беременности.</p></abstract><trans-abstract xml:lang="en"><p>   In women with a complex obstetric and gynecological history, miscarriage is a predominant concern. Steroidogenesis plays a crucial role in female reproductive health. Different genes involved in this process, the polymorphism of which may be associated with the risk of pregnancy loss. We analyzed CYP21A2, HSD3B2, CYP17A1, STAR, CYP11A1, POR genes using NGS, PCR-RFLP and MLPA methods in 30 women with a history of miscarriage and 46 individuals in the control group. A total of 142 nucleotide sequence variants were identified in both coding and non-coding regions of these genes, with different clinical significance. Pathogenic variants in the CYP21A2 gene were detected in 30 % of women with miscarriage compared to 6.5 % in the control group. One missense variant (rs17853284) with a potential pathogenic effect was identified in the POR gene. These findings suggest that heterozygous carriage in steroidogenesis-related genes, particularly CYP21A2, requares further investigation as potential predictors of possible obstetric complications.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>невынашивание беременности</kwd><kwd>стероидогенез</kwd><kwd>ген CYP21A2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>miscarriage</kwd><kwd>steroidogenesis</kwd><kwd>CYP21A2 gene</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках темы ФНИ № 1024032800068-4-3.2.2 «Разработка лечебных стратегий, направленных на активное долголетие женщин»</funding-statement><funding-statement xml:lang="en">The study was carried out within the framework of the topic of the Federal Research No. 1024032800068-4-3.2.2 «Development of treatment strategies aimed at active longevity of women»</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">Выкидыш.
