В проведенной работе были обследованы 102 ребенка с ФЕЖС. Всем пациентам выполнялась хирургическая гемодинамическая коррекция (ГК) врожденного порока сердца (ВПС). При ретроспективном анализе историй болезни у обследованных пациентов с ФЕЖС тромбоз диагностирован в 12,7% случаев. При анализе полиморфизма гена фермента MTR А2756G выявлены значимые различия в группе пациентов с тромбозом в анамнезе и без него.Результаты. Нами установлено, что риск развития тромбоза связан с носительством гомозиготного генотипа 2756АА гена фермента MTR (отношение шансов – ОШ = 11,21; 95% доверительный интервал – ДИ: 1,39–89,96; p = 0,023).</p></abstract><trans-abstract xml:lang="en"><p>Aim. To analyze the relationships between the carriage of polymorphic variants in the folate metabolism genes and the development of thrombotic complications in patients with single ventricle (SV) during surgical treatment.Material and Methods. A total of 102 children with SV were examined in the performed research. All patients underwent surgical hemodynamic correction of congenital heart disease (CHD). According to a retrospective chart review, thrombosis was diagnosed in 12.7 % of the examined patients with SV. The analysis of polymorphism in the MTR A2756G enzyme gene revealed significant differences between the groups of patients with a history of thrombosis and without it.Results. We found that the risk of developing thrombosis was associated with the carriage of homozygous genotype 2756AA of the MTR enzyme gene (OR = 11.21; 95% CI: 1.39–89.96; p = 0.023).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиморфизм генов фолатного обмена</kwd><kwd>гомоцистеин</kwd><kwd>тромбоз</kwd><kwd>функционально единственный желудочек сердца.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>folate metabolism gene polymorphism</kwd><kwd>homocysteine</kwd><kwd>thrombosis</kwd><kwd>single ventricle</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">Azzini E., Ruggeri S., Polito A.
