Out of 160 patients, 50.6% (n=81) were boys, 49.4% (n=79) were girls. All patients with diabetes were under the age of 18 years. As a control group, 271 students of the Medical College No. 1 were involved: 79 (29.1%) boys, 192 (70.9%) girls. The collected blood samples were sent for further investigation to the medical genetic laboratory where polymerase chain reaction-based genotyping of the samples was performed. </p> <p><bold>Results.</bold> For the first time, the relationship of diabetes with class II genes of the HLA system was studied. The Azerbaijani were found to have higher risk associated with HLA DQ2 molecule. The molecule HLA DQ8 also increases risk, although it is lower in comparison with HLA DQ2 molecule. What is unusual is that for this population the allele HLA DQB1*0304 was also associated with the risk of diabetes. </p> <p><bold>Conclusion.</bold> The haplotype DQB1*0302-DQA1*03/DQB1*02-DQA1*05 (DQ8/DQ2.5) associated with high risk of diabetes is found in 3% of the representatives of the population of Azerbaijan, which is estimated as the average prevalence of diabetes.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель.</bold> Проведение сравнительного анализа генов DQB1 и DQA1 II класса системы человеческих лейкоцитарных антигенов (HLA) в азербайджанской популяции. </p> <p><bold>Методы.</bold> Нами были изучены аллели гена НLA DQ и субтипы НLA DRB1*04 у 160 детей, больных сахарным диабетом, и 271 здорового ребёнка в азербайджанской популяции. Из 160 больных 50,6% (n=81) составили мальчики, 49,4% (n=79) - девочки. Все больные сахарным диабетом были в возрасте до 18 лет. В качестве группы сравнения был привлечён 271 учащийся медицинского колледжа №1: 79 (29,1%) мальчиков и 192 (70,9%) девочки. Собранные образцы крови были отправлены для дальнейшего исследования в медико-генетическую лабораторию, где проводилось генотипирование образцов при помощи полимеразной цепной реакции. </p> <p><bold>Результаты.</bold> Впервые была изучена взаимосвязь сахарного диабета с генами II класса системы НLA. Установлено, что у азербайджанцев более высокий риск ассоциируется с молекулой НLA DQ2. Молекула НLA DQ8 также создаёт риск, хотя и меньший в сравнении с молекулой НLA DQ2. Необычным оказался тот факт, что для этой популяции аллель НLA DQB1*0304 также был связан с риском сахарного диабета. </p> <p><bold>Вывод.</bold> Связанный с высоким риском сахарного диабета гаплотип DQB1*0302-DQA1*03/DQB1*02-DQA1*05(DQ8/DQ2.5) встречается у 3% представителей азербайджанской популяции, что расценивается как средняя частота сахарного диабета.</p></trans-abstract><kwd-group xml:lang="en"><kwd>human leukocyte antigen system</kwd><kwd>diabetes mellitus</kwd><kwd>gene polymorphism</kwd><kwd>prognosis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>система человеческих лейкоцитарных антигенов</kwd><kwd>сахарный диабет</kwd><kwd>полиморфизм генов</kwd><kwd>прогноз</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Eisenbarth G.S.
