Диагноз подагры выставлен согласно классификационным критериям ACR/EULAR, 2015. Материалом для исследования являлась ДНК, выделенная из лейкоцитов цельной периферической крови. Все пациенты были генотипированы для выявления полиморфизма локуса С421A (rs2231142, Q141K) гена ABCG2. Статистическая обработка данных проводилась с помощью пакета статистических программ Statistica 10,0. </p></sec><sec><title>Результаты</title><p>Результаты. Полученные результаты исследования полиморфизма С421A (rs2231142, Q141K) гена ABCG2 продемонстрировали высокую частоту встречаемости мутантного аллеля А (χ2 = 5,58, р = 0,018, OR = 3,5, CI95% = 1,16–10,52) и генотипа С/А (χ2 = 5,03, р = 0,024, OR = 3,5, CI95% = 1,11–10,98) среди больных подагрой по сравнению с группой контроля. Данный факт указывает на значимость локуса rs2231142 гена ABCG2 в развитии подагры и позволяет рассматривать носительство минорного (А) аллеля и генотипа С/А как молекулярно-генетический фактор развития заболевания. Носительство же аллеля дикого типа (С) и генотипа C/С оказывает протективный характер, снижая риск развития заболевания в 3,5 раза.</p></sec><sec><title>Заключение</title><p>Заключение. ABCG2 С421A (rs2231142, Q141K) ассоциирован с высоким риском развития подагры в популяции жителей Забайкальского края. Полиморфизм гена ABCG2 может рассматриваться как генетический предиктор более высокого риска развития подагры.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the frequency distribution of alleles and genotypes of the C421A locus (rs2231142, Q141K) of the ABCG2 gene in patients with gout and to evaluate their association with the risk of the disease development.</p></sec><sec><title>Methods</title><p>Methods. 80 patients (69 men and 11 women) with gout (mean age 54.8±12.4 years) were examined. Gout was diagnosed according to the ACR/EULAR classification criteria, 2015. The material for the study was DNA isolated from leukocytes of the whole peripheral blood. All patients were genotyped to detect polymorphism of the C421A locus (rs2231142, Q141K) of the ABCG2 gene. Statistical data processing was performed using Statistica 10.0 statistical software package.</p></sec><sec><title>Results</title><p>Results. The results of the study of the C421A polymorphism (rs2231142, Q141K) of the ABCG2 gene demonstrated a high frequency of mutant A (χ2 = 5.58, p = 0.018, OR = 3.5, CI95% = 1.16–10.52) genotypes C/A (χ2 = 5.03, p = 0.024, OR = 3.5, CI95% = 1.11–10.98) among patients with gout compared with the control group. This fact indicates the significance of the ABCG2 gene rs2231142 locus in the development of gout and allows us to consider the carriage of the minor (A) allele and the C/A genotype as a molecular genetic factor in the development of the disease. The carriage of the wild-type allele (C) and the C/C genotype has a protective character, reducing the risk of developing the disease by 3.5 times.</p></sec><sec><title>Conclusion</title><p>Conclusion. ABCG2 C421A (rs2231142, Q141K) is associated with a high risk of developing gout among population of Zabaikalsky Krai. ABCG2 gene polymorphism can be considered as a genetic predictor of a higher risk of developing gout.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>Подагра</kwd><kwd>Мочевая кислота</kwd><kwd>Генетический полиморфизм</kwd><kwd>ABCG2</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Gout</kwd><kwd>Uric acid</kwd><kwd>Genetic polymorphism</kwd><kwd>ABCG2</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">Атаханова Л.Э., Цурко В.В., Булеева И.М., Бойко И.Н., Железнов С.П., Иванова Т.Б.
