To study the association of the hereditary sick sinus syndrome (SSS) with gene α2B-adrenergic receptor (ADRA2B) polymorphism.</p></sec><sec><title>Material and methods</title><p>Material and methods. 29 families with hereditary primary SSS from the database of the Chair of Therapy № 1 of Krasnoyarsk State Medical University named after prof. V.F. Voyno-Yasenetsky were included in the study. Group 1 included probands (20 women and 9 men, 58±0.15 y.o.), group 2 – proband relatives of I, II and III degree (65 males and 68 females, 39±0.13 y.o.), group 3 (control) — 89 healthy volunteers. Clinical examination (physical examination, ECG, bicycle ergometry, ECG monitoring, atropine test, electrophysiological study, echocardiography) was performed in all probands and their relatives. The diagnosis of SSS was confirmed by transesophageal left atrium stimulation in 75 individuals. Genotypic examination of gene ADRA2B I/D polymorphism was performed in 213 individuals: 75 SSS-patients, 49 their healthy relatives, 89 healthy volunteers.</p></sec><sec><title>Results</title><p>Results. 3 types of ADRA2B genotypes (II — homozygous wild, ID — heterozygous, DD — homozygous mutant) were founded by allele-specific polymerase chain reaction. Significant prevalence of the homozygous genotype of more rare alleles DD in SSS-patients (28±5.2%) compared to the control group (8.99±3.0%) was found.</p></sec><sec><title>Conclusion</title><p>Conclusion. Study of the genetic marker can be used to identify predisposition to hereditary SSS in the population and individual-family level. SSS due to mutations in genes that regulate cell function of sinus node and the sinoatrial conduct occurs, apparently, extremely rarely.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучить ассоциацию наследственного синдрома слабости синусового узла (СССУ) с полиморфизмом гена α2В-адренергического рецептора (ADRA2B).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Из базы данных кафедры терапии №1 Красноярского государственного медицинского университета им. проф. В.Ф. Войно-Ясенецкого были отобраны 29 семей, имеющих первичный наследственный СССУ. Среди пробандов было 20 женщин и 9 мужчин в возрасте 58±0,15 лет. Среди родственников I, II и III степени родства было 65 мужчин и 68 женщин в возрасте 39±0,13 лет. Всем пробандам и их родственникам было проведено клинико-инструментальное исследование: клинический осмотр, электрокардиография, велоэргометрия, холтеровское мониторирование ЭКГ, атропиновая проба, электрофизиологическое исследование, эхокардиоскопия. Молекулярно-генетическое исследование проводилось в лаборатории медицинской генетики НИИ терапии Сибирского отделения РАМН Новосибирска. По полиморфизму I/D гена ADRA2B было прогенотипировано 75 больных СССУ (диагноз подтвержден с помощью чреспищеводной стимуляции левого предсердия), 49 их здоровых родственников I, II и III степени родства и 89 лиц контрольной группы.</p></sec><sec><title>Результаты</title><p>Результаты. По результатам аллель-специфической полимеразной цепной реакции выявлены 3 вида генотипов ADRA2B у больных СССУ, их здоровых родственников и лиц контрольной группы: II — гомозиготный дикий, ID — гетерозиготный, DD — гомозиготный мутантный. Установлено достоверное преобладание гомозиготного генотипа по более редкому аллелю DD у больных СССУ (28±5,2%) по сравнению c лицами контрольной группы (8,99±3,0%).</p></sec><sec><title>Заключение</title><p>Заключение. Изученный генетический маркер может быть использован для выявления предрасположенности к наследственному СССУ на популяционном и индивидуально-семейном уровне. СССУ, обусловленный мутациями в генах, регулирующих функционирование клеток синусового узла и сино-атриального проведения, встречается, по-видимому, исключительно редко.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>α2В-адренергический рецептор</kwd><kwd>полиморфизм</kwd><kwd>синдром слабости синусового узла</kwd></kwd-group><kwd-group xml:lang="en"><kwd>α2B-adrenergic receptor</kwd><kwd>polymorphism</kwd><kwd>sick sinus syndrome</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">Benson D.W.
