В регуляторных областях кодирующего VEGF гена выявлен ряд полиморфных сайтов, влияющих на уровень экспрессии и связанных с уровнем его белковой продукции. Полиморфизм VEGF-2758 C/A (rs699947) расположен в промоторной области гена. При этом VEGF-2578 СС генотип ассоциирован с более высоким уровнем продукции относительно других генотипов. Полиморфизм VEGF 936 C/T (rs3025039) расположен в 3` нетранслируемой области гена VEGF, и аллель Т ассоциирован со сниженным плазменным уровнем белка. Цель исследования – анализ ассоциированности полиморфных позиций регуляторных регионов гена VEGF (rs699947 и rs3025039) с тяжестью течения заболевания и сердечно-сосудистыми проблемами у пациентов Западно-Сибирского региона России, перенесших COVID-19. В исследование включено 260 пациентов, переболевших COVID-19 с разной степенью тяжести. При обследовании учитывалось наличие сердечно-сосудистых заболеваний (ССЗ) в анамнезе и впервые возникших после COVID-19. Генотипирование VEGF rs699947 и VEGF rs3025039 осуществляли методом TagMan зондов. Достоверность различий частот распределения изучаемых признаков в группах определяли по двустороннему варианту точного метода Фишера. Нами не выявлено различий в распределении частот генотипов единичных полиморфных позиций и сложного генотипа VEGF-2578/VEGF+936 между группами с разной степенью тяжести протекания заболевания – тяжелой, средней, легкой как в общей группе пациентов, так и в субгруппе пациентов, отягощенных наличием сердечно-сосудистых заболеваний в анамнезе. Кроме того, не выявлено достоверно значимых различий между пациентами с вновь возникшими сердечно-сосудистыми осложнениями после перенесенной инфекции относительно переболевших пациентов без аналогичных осложнений, как по единичным генотипам, так и в комплексах VEGF-2578/VEGF+936. По нашим данным, функциональный полиморфизм VEGF-гена в анализируемых позициях не ассоциирован ни с тяжестью течения COVID-19, ни с сердечно-сосудистыми нарушениями при заболевании. Изменения уровня VEGF при развитии инфекционного заболевания могут быть связаны с изменением факторов на него влияющих, что требует дополнительного изучения.</p></abstract><trans-abstract xml:lang="en"><p>VEGF-A is significant cytokine associated with angiogenesis. In SARS-CoV-2 infection (COVID-19), an increased level of VEGF-A was detected in serum being associated with severity and mortality of the disease. A number of polymorphic sites have been identified in regulatory regions of this gene that are associated with VEGF production. The VEGF-2758 (rs699947) is located in promoter region of this gene and the VEGF-2578 CC genotype is associated with higher production rates. The VEGF 936 (rs3025039) is located at the 3' untranslated region of VEGF gene, and its T allele is associated with a reduced plasma protein level. The aim of the study was to analyze the association of polymorphic positions of the regulatory regions of the VEGF gene (rs699947 and rs3025039) with clinical severity of the disease and cardiovascular problems in patients from the West Siberian region of Russia who previously suffered with COVID-19. The study included 260 former COVID-19 patients with varying degrees of severity. The examination took into account the previous history of cardiovascular diseases (CVD) and those with first clinical CVD signs occuring after the infection. VEGF rs699947 and VEGF rs3025039 were genotyped using TagMan probes. The significance of distribution differences in the studied genetic features was determined using a two-way version of the exact Fisher test. We did not find any differences in distribution of the genotype frequencies, both for single polymorphic positions and the complex VEGF-2578/VEGF+936 between the groups with varying degrees of the disease severity (severe, moderate, and mild), both in general group of patients, and in the subgroup of patients with CVD history. Moreover, there were no significant differences revealed between patients with newly emerged CVD after infection compared to patients without similar complications, both for single genotypes and in VEGF-2578/VEGF+936 complexes. According to our data, the functional polymorphism of the VEGF gene at these gene locuses is not associated with either COVID-19 severity, or with cardiovascular disorders accompanying the disease. Changes in VEGF levels may be due to various factors affecting it, thus requiring additional studies.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>тяжесть течения</kwd><kwd>сердечно-сосудистые заболевания</kwd><kwd>VEGF полиморфизм</kwd><kwd>регуляторные регионы гена</kwd><kwd>постковидные осложнения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>clinical severity</kwd><kwd>cardiovascular diseases</kwd><kwd>VEGF polymorphism</kwd><kwd>regulatory regions</kwd><kwd>post-COVID complications</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Профилактика, диагностика и лечение новой коронавирусной инфекции (COVID-19: временные методические рекомендации Министерства здравоохранения Российской Федерации.
