Однако тромбоэмболическое состояние отмечается не у всех больных.</p><p>Целью исследования стала оценка частоты носительства полиморфных генов свертывающей системы крови и генов метаболизма фолатов и вклада генетических вариантов в развитие тромбозов у пациентов с хронической Ph-негативной миелопролиферативной неоплазией (ХМПН).</p><sec><title>Материалы и методы</title><p>Материалы и методы. Молекулярно-генетическое тестирование на наличие генетических вариантов с оценкой частоты их встречаемости и аллельной нагрузки было проведено у 142 пациентах с ХМПН. Исследовались полиморфизмы генов фолатного цикла – A2756G (Asp919Gly) гена MTR, C677T (Ala22Val) гена MTHFR, A66G (ILe22Met) гена MTRR (rs1801394), а также мутаций генов факторов свертывания крови – G( 455)A гена FGB, G20210A гена F2, G10976A (Arg353Gln) гена F7, G1691A (Arg506Gln) гена F5. Исследование проводилось методом полимеразной цепной реакции (ПЦР) в реальном времени; биологическим материалом для теста служила цельная кровь.</p></sec><sec><title>Результаты и обсуждение</title><p>Результаты и обсуждение. Исследование показало, что лишь 6 из 50 (12%) пациентов с тромботическими осложнениями не имели изменений в изучаемых генах, тогда как у 88% пациентов был обнаружен тот или иной генотипический вариант, что может свидетельствовать о высокой вероятности вовлечения наследственного генетического фактора в развитие гиперкоагуляции и тромботических осложнений у больных ХМПН.</p></sec><sec><title>Выводы</title><p>Выводы. Всестороннее исследование роли, взаимодействия и условий функционирования генов, контролирующих процессы свертывания крови у больных Ph-отрицательными ХМПН, позволит понять причины нарушений системы гемостаза и разработать эффективные меры по профилактике тромботических осложнений у данной категории больных.</p></sec></abstract><trans-abstract xml:lang="en"><p>Thrombotic complications often complicate the course of the underlying disease in patients with chronic myeloproliferative neoplasia. However, a thromboembolic condition is not observed in all patients.</p><p>The aim of the study was to assess the carriage frequency of polymorphic genes of the blood coagulation system and folate metabolism genes and the contribution of genetic variants to the development of thrombosis in patients with chronic Ph-negative myeloproliferative neoplasia (CMPN).</p><sec><title>Materials and methods</title><p>Materials and methods. Molecular genetic testing for the presence of genetic variants with an assessment of their frequency of occurrence and allelic load was carried out in 142 patients with CMPN. We studied polymorphisms of the folate cycle genes – A2756G (Asp919Gly) of the MTR gene, C677T (Ala22Val) of the MTHFR gene, A66G (ILe22Met) of the MTRR gene (rs1801394), as well as mutations of the genes of blood coagulation factors – G(455)A of the FGB gene, G20210A of the F2 gene, G10976A (Arg353Gln) of the F7 gene, G1691A (Arg506Gln) of the F5 gene.

The study showed that only 6 out of 50 (12%) patients with thrombotic complications had no changes in the genes studied, while 88% of patients had one or another genotypic variant, which may indicate a high probability of involvement of a hereditary genetic factor in the development of hypercoagulability and thrombotic complications in patients with chronic MPN.</p></sec><sec><title>Conclusions</title><p>Conclusions. A comprehensive study of the role, interaction and operating conditions of genes that control blood coagulation processes in patients with Ph-negative chronic MPN will make it possible to understand the causes of hemostatic system disorders and develop effective measures to prevent thrombotic complications in this category of patients.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>тромбозы</kwd><kwd>генетические полиморфизмы</kwd><kwd>гены гемостаза</kwd><kwd>гены фолатного цикла</kwd><kwd>миелопролиферативные неоплазии</kwd></kwd-group><kwd-group xml:lang="en"><kwd>thrombosis</kwd><kwd>genetic polymorphisms</kwd><kwd>hemostasis genes</kwd><kwd>folate cycle genes</kwd><kwd>myeloproliferative neoplasia</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">Андреенко Е.
