Использованы данные геномной базы по результатам генотипирования 1900 условно здоровых лиц казахской национальности ~2,5 млн SNP с использованием чипов OmniChip 2,5 M Illumina в Геномном центре DECODE Iceland в рамках совместного проекта «Генетические исследования преэклампсии в популяциях Центральной Азии и Европы» (InterPregGen) 7 рамочной программы Европейской Комиссии по Грантовому соглашению №. 282540. Результаты показывают значительное межпопуляционное разнообразие в частоте минорных аллелей анализируемых SNP. Восточноазиатские популяции демонстрируют наиболее выраженные отличия от европейских и казахстанской популяции, что может быть связано с генетической изоляцией и историческими миграционными процессами. Проведенный геномный анализ обусловил выбор полиморфизмов генов про- и противовоспалительной системы и иммунного ответа для их дальнейшего репликативного генотипирования у пациенток с иПНБ в казахской популяции. Полученные результаты будут служить основой для разработки эффективных методов ранней диагностики.</p></abstract><trans-abstract xml:lang="en"><p>Objective: To investigate the population-specific features of immune response gene polymorphisms, including IFNG (rs2069727), IL1B (rs1143634), IL6 (rs1800796), IL10 (rs1800896), CX3CR1 (rs3732379), and CTLA4 (rs3087243), which are associated with the development of idiopathic recurrent pregnancy loss (iRPL) in an ethnically homogeneous Kazakh population. Additionally, to conduct a comparative analysis with previously studied global populations. Methods: Genomic database analysis was performed using genotyping data from 1,900 conditionally healthy Kazakh individuals, covering approximately 2.5 million SNPs. The data were obtained using OmniChip 2.5M Illumina arrays at the DECODE Genomics Center in Iceland as part of the collaborative “Genetic Studies of Preeclampsia in Central Asian and European Populations” (InterPregGen) project, funded by the 7th Framework Program of the European Commission (Grant Agreement No. 282540). Results: The study reveals significant inter-population diversity in the minor allele frequencies (MAFs) of the analyzed SNPs. East Asian populations exhibit the most distinct differences compared to European and Kazakh populations, likely due to genetic isolation and historical migration processes. Conclusion: The genome-wide analysis has guided the selection of pro- and anti-inflammatory immune system gene polymorphisms for further replication genotyping in Kazakh women with iRPL. The obtained results will serve as a foundation for developing effective early diagnostic methods for idiopathic recurrent pregnancy loss.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфизм генов</kwd><kwd>генотипы</kwd><kwd>идиопатическая форма привычного невынашивания беременности</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene polymorphism</kwd><kwd>genotypes</kwd><kwd>idiopathic recurrent pregnancy loss</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках проекта «Генетические исследования преэклампсии в популяциях Центральной Азии и Европы» (InterPregGen) 7 рамочной программы Европейской Комиссии по Грантовому соглашению № 282540.</funding-statement><funding-statement xml:lang="en">This work was carried out within the framework of the project “Genetic studies of preeclampsia in Central Asian and European populations” (InterPregGen), funded by the European Commission’s 7th Framework Programme under Grant Agreement No. 282540.</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">Practice Committee of the American Society for Reproductive Medicine.
