Преэклампсия является одной из наиболее распространенных акушерских проблем, на долю которой приходится почти 15% заболеваний, связанных с беременностью. В различных исследованиях оценивалась ассоциация между вариантом G1378T rs4961 гена ADD1 и риском развития преэклампсии, однако результаты остаются противоречивыми.</p></sec><sec><title>Цель</title><p>Цель: в ходе метаанализа изучить ассоциацию варианта rs4961 гена ADD1 с риском развития преэклампсии.</p></sec><sec><title>Методы</title><p>Методы. С использованием протокола PRISMA в базе данных PubMed, поисковой системе Google Scholar и российской научной электронной библиотеке CyberLeninka.ru были собраны данные о варианте rs4961 гена ADD1 при преэклампсии в 8 исследованиях. Для проведения метаанализа использовалось программное обеспечение ReviewManager (RevMan) 5.4. Для оценки ассоциации между вариантом rs4961 гена ADD1 и риском развития преэклампсии было рассчитано отношение шансов (ОШ) с 95%-ным доверительным интервалом (ДИ) при доминантной, рецессивной и аллельной моделях наследования.</p></sec><sec><title>Результаты</title><p>Результаты. Значимых ассоциаций обнаружено не было ни для одной из моделей: GG + GТ против TT (ОШ = 1,63; 95% ДИ: 0,96, 2,75, p = 0,07); GG против GT + TT (ОШ = 1,47; 95% ДИ: 0,92, 2,33, p = 0,10); G против T (ОШ = 1,55; 95% ДИ: 0,93, 2,58, p = 0,09). Анализ подгрупп выявил статистически значимую связь варианта rs4961 гена ADD1 с риском развития преэклампсии в российских популяциях. Наличие генотипа TT увеличивает риск преэклампсии в 2 раза (ОШ = 2,07; 95% ДИ: 1,00, 4,30, p = 0,05).</p></sec><sec><title>Выводы</title><p>Выводы. Результаты метаанализа указывают на отсутствие ассоциации варианта rs4961 гена ADD1 с преэклампсией. Однако результаты анализа подгрупп показали, что у россиян генотип TT ассоциирован с высоким риском развития преэклампсии. Это говорит о том, что влияние варианта rs4961 на патогенез преэклампсии имеет популяционные особенности.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Preeclampsia is one of the most common obstetric problems, accounting for almost 15% of pregnancy-related pathologies. Various studies have evaluated the association of G1378T rs4961 variant in ADD1 gene with the risk of preeclampsia. However, results remain contradictory.</p></sec><sec><title>Aim</title><p>Aim. To examine the association of the ADD1 rs4961 genetic variant with the risk of preeclampsia through meta-analysis.</p></sec><sec><title>Methods</title><p>Methods. By searching according to the PRISMA protocol in the PubMed database, Google scholar search engine and the Russian scientific electronic library CyberLeninka.ru data on rs4961 variant of ADD1 gene in preeclampsia were collected from 8 studies. The ReviewManager (RevMan) 5.4 software was used to conduct meta-analysis. To assess the association of rs4961 variant of ADD1 gene with the risk of preeclampsia, odds ratio (OR) with a 95% confidence interval (CI) at allelic, dominant, and recessive models was calculated.</p></sec><sec><title>Results</title><p>Results. No significant associations were found at any of these models: G versus T (OR = 1.55; 95% CI: 0.93, 2.58, P = 0.09), GG + GT versus TT (OR = 1.63; 95% CI: 0.96, 2.75, P = 0.07) and GG versus GT + TT (OR = 1.47; 95% CI: 0.92, 2.33, P = 0.10). Subgroup analysis revealed a statistically significant association between the ADD1 gene variant rs4961 and the risk of developing preeclampsia in Russian populations. The presence of the (TT) genotype doubles the risk of preeclampsia (OR = 2.07; 95 % CI: 1.00, 4.30, P = 0.05).</p></sec><sec><title>Conclusions</title><p>Conclusions. The results of the meta-analysis indicate no association between the ADD1 gene variant rs4961 and preeclampsia. However, subgroup analysis revealed that the (TT) genotype is associated with a high risk of preeclampsia in the Russian population. This suggests that the effect of the rs4961 variant on the pathogenesis of preeclampsia exhibits population specific characteristics. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>вариант гена</kwd><kwd>G1378T rs4961 ADD1</kwd><kwd>преэклампсия</kwd><kwd>метаанализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gene variant</kwd><kwd>G1378T rs4961 ADD1</kwd><kwd>preeclampsia</kwd><kwd>meta-analysis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа была выполнена при финансовой поддержке Министерства науки и высшего образования РФ в рамках государственного задания в сфере научной деятельности № FENW-2026-0030.</funding-statement><funding-statement xml:lang="en">The work was carried out under the state assignment of the Ministry of Science and Higher Education of the Russian Federation No. FENW-2026-0030.</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">Moser M.
