Для СПКЯ характерны окислительный стресс и снижение антиоксидантного статуса. Активность антиоксидантных ферментов генетически детерминирована и зависит от наличия полиморфных аллелей. Показано, что полиморфный вариант Ala16Val гена SOD2 может приводить к истощению фермента и быть ассоциированным с риском развития СПКЯ. В литературе присутствуют противоречивые данные об ассоциации полиморфного локуса rs4880 гена SOD2 с СПКЯ. Цель исследования: Исследовать ассоциацию полиморфного локуса Val16Ala гена митохондриальной супероксиддисмутазы (SOD2) с синдромом поликистоза яичников по протоколу проведения систематических обзоров и мета-анализов PRISMA в исследованиях &amp;laquo;случай-контроль&amp;raquo;. Материалы и методы Проведен всесторонний поиск по электронным базам данных, включая PubMed, eLibrary, Science Direct, Google Scholar, EMBASE, Scopus и Кокрановскую библиотеку исследований, опубликованных до декабря 2022 года и посвященных поиску ассоциаций между полиморфизмом rs4880 в гене SOD2 и СПКЯ. Поиск проводился по следующим ключевым словам: &amp;laquo;Синдром поликистозных яичников&amp;raquo; или &amp;laquo;СПКЯ&amp;raquo;, &amp;laquo;супероксиддисмутаза 2&amp;raquo; или &amp;laquo;SOD2&amp;raquo; или &amp;laquo;MnSOD&amp;raquo;, &amp;laquo;полиморфизм&amp;raquo; или &amp;laquo;SNP&amp;raquo; или &amp;laquo;вариант&amp;raquo; или &amp;laquo;rs4880&amp;raquo; или Ala16Val или C47T на английском, арабском и русском языках. Из 95 релевантных публикаций критериям соответствовали 6 подходящих исследований &amp;laquo;случай-контроль&amp;raquo; с 1606 случаями СПКЯ и 1333 контролями для включения в данный мета-анализ. Большинство отобранных исследований были проведены в Западной Азии. Мета-анализ проводился в соответствии с протоколом PRISMA и использованием Review Manager версии 5.4. Результаты: Показано, что наличие, по крайней мере, одной копии T-аллеля в полиморфном локусе rs4880 у пациентов с СПКЯ увеличивает риск развития синдрома в трех генетических моделях: доминантной, аллельной и гетерозиготной. Заключение: Результаты мета-анализа демонстрируют, что полиморфизм rs4880 гена SOD2 может быть фактором риска развития СПКЯ, и предполагается, что аллель Val может повышать риск развития СПКЯ</p></abstract><trans-abstract xml:lang="en"><p>Background: According to WHO, approximately 8-13% of women of reproductive age suffer from polycystic ovary syndrome (PCOS), while up to 70% of women worldwide with PCOS remain undiagnosed. PCOS is the most common cause of anovulation and the main cause of infertility. PCOS is characterized by oxidative stress and a decrease in antioxidant status. The activity of antioxidant enzymes is genetically determined and depends on the presence of polymorphic alleles, and it has been shown that the polymorphic variant Ala16Val of the SOD2 gene can lead to enzyme depletion and be associated with the risk of PCOS. There are contradictory data in the literature on the association of the polymorphic locus rs4880 of the SOD2 gene with PCOS. The aim of the study: To investigate the association of the polymorphic locus Val16Ala of the mitochondrial superoxide dismutase (SOD2) gene with polycystic ovarian syndrome according to the PRISMA protocol of systematic reviews and meta-analyses in case-control studies. Materials and methods: A comprehensive search was conducted on electronic databases, including PubMed, eLibrary, Science Direct, Google Scholar, EMBASE, Scopus and the Cochrane Library of studies published before December 2022 and devoted to the search for associations between rs4880 polymorphism in the SOD2 gene and PCOS. The search was conducted by the following keywords: &amp;quot;Polycystic ovary syndrome&amp;quot; or &amp;quot;PCOS&amp;quot;, &amp;quot;superoxide dismutase 2&amp;quot; or &amp;quot;SOD2&amp;quot; or &amp;quot;MnSOD&amp;quot;, &amp;quot;polymorphism&amp;quot; or &amp;quot;SNP&amp;quot; or &amp;quot;variant&amp;quot; or &amp;quot;rs4880&amp;quot; or Ala16Val or C47T in English, Arabic and Russian. Out of 95 relevant publications, 6 suitable case-control studies with 1,606 cases of PCOS and 1,333 controls met the criteria for inclusion in this meta-analysis. Most of the selected studies were conducted in Western Asia. The meta-analysis was carried out in accordance with the PRISMA protocol and using Review Manager version 5.4. Results: It has been shown that the presence of at least one copy of the T-allele in the polymorphic locus rs4880 in patients with PCOS was shown to increase the risk of developing the syndrome in three genetic models: dominant, allelic and heterozygous. Conclusion: The results of the meta-analysis demonstrate that the rs4880 polymorphism of the SOD2 gene may be a risk factor for the development of PCOS, and it is assumed that the Val allele may increase the risk of developing PCOS</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мета-анализ</kwd><kwd>СПКЯ</kwd><kwd>rs4880</kwd><kwd>SOD2</kwd><kwd>Ala16Val</kwd><kwd>PRISMA</kwd><kwd>бесплодие</kwd></kwd-group><kwd-group xml:lang="en"><kwd>meta-analysis</kwd><kwd>PCOS</kwd><kwd>rs4880</kwd><kwd>SOD2</kwd><kwd>Ala16Val</kwd><kwd>PRISMA</kwd><kwd>infertility</kwd></kwd-group></article-meta></front><back><ref-list><title>Список литературы</title><ref id="B1"><mixed-citation>WHO.
