Аннотация

Цель. Изучить вовлеченность полиморфизма генов факторов роста и их рецепторов в формирование задержки роста плода (ЗРП).
Материалы и методы. В рамках данного проспективного сравнительного исследования у 196 беременных с ЗРП и 324 беременных контрольной группы выполнен генетический анализ 5 полиморфных локусов генов факторов роста и их рецепторов (rs4444903 EGF, rs833061 VEGFA, rs2981582 FGFR2, rs6214 IGF1, rs1800469 TGFβ1). Для генотипирования однонуклеотидного полиморфизма использовался метод полимеразной цепной реакции. Оценка медико-биологических механизмов, лежащих в основе выявленных ассоциаций, проводилась с применением современных биоинформатических ресурсов: GTExportal (влияние на транскрипцию генов) и HaploReg (регуляторный потенциал).
Результаты. Аллельный вариант G rs4444903 гена EGF определяет повышенный риск возникновения ЗРП в рамках следующих генетических моделей: аллельной (отношение шансов – ОШ 1,28, 95% доверительный интервал – ДИ 1,00–1,65; рperm=0,033), аддитивной (ОШ 1,33, 95% ДИ 1,02–1,75; рperm=0,039) и доминантной (ОШ 1,62, 95% ДИ 1,06–2,47; рperm=0,031). Полиморфизм rs4444903 гена EGF обладает существенным эпигенетическим потенциалом (в области промоторов, энхансеров, «открытого хроматина», белков – регуляторов транскрипции), детерминирует экспрессию генов EGF и GAR1 и альтернативный сплайсинг гена GAR1 в органах и тканях (плацента, головной мозг плода и взрослого организма и др.), являющихся значимыми для патофизиологии ЗРП.
Заключение. Показаны ассоциации rs4444903 гена EGF с формированием ЗРП.

Aim. To study the involvement of polymorphism of growth factor genes and their receptors in the formation of fetal growth retardation (FGR).
Materials and methods. In this prospective comparative study, genetic analysis of five polymorphic loci of growth factor genes and their receptors (rs4444903 EGF, rs833061 VEGFA, rs2981582 FGFR2, rs6214 IGF1, rs1800469 TGFß1) was performed in 196 pregnant women with FGR and 324 pregnant women in the control group. For genotyping single-nucleotide polymorphism, the polymerase chain reaction method was used. The biomedical mechanisms underlying the identified associations were evaluated using modern bioinformatic resources: GTExportal (effect on gene transcription) and HaploReg (regulatory potential).
Results. The allelic variant G rs4444903 of the EGF gene determines an increased risk of FGR in the following genetic models: allelic (OR 1.28, 95% CI 1.00–1.65; рperm=0.033), additive (OR 1.33, 95% CI 1.02–1.75; рperm=0.039) and dominant (OR 1.62, 95% CI 1.06–2.47; рperm=0.031). The polymorphism rs4444903 of the EGF gene has a significant epigenetic potential (in the field of promoters, enhancers, "open chromatin", transcription regulatory proteins), determines the expression of the EGF and GAR1 genes and alternative splicing of the GAR1 gene in organs and tissues (placenta, fetal and adult brain, etc.), which are significant for the pathophysiology of FGR.
Conclusion. The associations rs4444903 of the EGF gene with the FGR are shown.
