В исследование включено 255 историй родов. Первая группа – контрольная – 70 случаев нормальных родов у условно здоровых беременных. Вторая группа – 90 случаев родов с задержкой роста плода без клиники преэклампсии. Третья группа – 95 случаев родов с диагностированной ранней преэклампсией и задержкой роста плода в сроке гестации 20–34 недели. У пациенток всех групп определяли генетические полиморфизмы, ассоциированные с системой гемостаза и метаболизма фолатов, методом ПЦР в режиме реального времени. Для анализа эпистаза применялся метод Generalized Multifactor Dimensionality Reduction v. 0.7. Построены прогностические модели различной сложности. Для группы с задержкой роста плода без клиники преэклампсии наилучшие показатели продемонстрировала трехлокусная модель. Для группы с задержкой роста плода с клиникой преэклампсии наиболее эффективной оказалась пятилокусная модель. Выявлены специфические генотипические профили высокого риска для каждой формы патологии. Установлены варианты генетической архитектуры изолированной задержки роста плода и задержки роста плода, ассоциированной с преэклампсией. Комбинированный анализ полиморфизмов генов гемостаза и фолатного цикла позволяет осуществлять раннюю предикцию и стратификацию риска плацентарных нарушений.</p></abstract><trans-abstract xml:lang="en"><p>To investigate the frequency of single nucleotide polymorphisms in genes of the hemostatic system and the folate cycle, as well as their intergenic interactions, in patients with antenatally diagnosed fetal growth restriction with and without clinical manifestations of preeclampsia. The study included 255 delivery records. The first (control) group consisted of 70 cases of normal deliveries in conditionally healthy pregnant women. The second group comprised 90 cases of deliveries complicated by fetal growth restriction without clinical signs of preeclampsia. The third group included 95 cases of deliveries with diagnosed early–onset preeclampsia and fetal growth restriction at a gestational age of 20–34 weeks. In patients from all groups, genetic polymorphisms associated with the hemostatic system and folate metabolism were determined using real-time polymerase chain reaction. Epistasis analysis was performed using the Generalized Multifactor Dimensionality Reduction (GMDR) v. 0,7 method. Predictive models of varying complexity were constructed. For the group with fetal growth restriction without clinical preeclampsia, the three-locus model. For the group with fetal growth restriction accompanied by preeclampsia, the most effective was the five–locus model. Specific high-risk genotypic profiles were identified for each form of the pathology. Distinct variants of the genetic architecture underlying isolated fetal growth restriction and fetal growth restriction associated with preeclampsia were identified. Combined analysis of polymorphisms in hemostasis- and folate cycle related genes enables early prediction and risk stratification of placental disorders.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>задержка роста плода</kwd><kwd>преэклампсия</kwd><kwd>полиморфизмы генов</kwd><kwd>гемостаз</kwd><kwd>фолатный цикл</kwd><kwd>GMDR-анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cystic fibrosis</kwd><kwd>pediatrics</kwd><kwd>targeted therapy</kwd><kwd>CFRT- protein</kwd><kwd>patient</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Грант Министерства науки и высшего образования Российской Федерации Федерального государственного бюджетного научного учреждения «Научно-исследовательский институт акушерства, гинекологии и репродуктологии им.
