The study included 253 people (122 patients diagnosed with morphologically verified sarcoidosis with lung involvement (average age – 41.00 ± 12.56 years) and 131 healthy people (control group) (average age – 44.00 ± 14.23). The distribution of alleles and genotypes of polymorphic markers rs2295080 and rs1883965 of the <italic>MTOR</italic> gene was analyzed in the study groups. There was a statistically significant increase in the level of mRNA expression of the <italic>MTOR</italic> gene in PBL of patients with pulmonary sarcoidosis compared with the control group (<italic>p</italic> = 0.007). A decrease in the number of transcripts of this gene was noted in patients receiving therapy compared with patients without therapy (<italic>p</italic> = = 0.025). There were no statistically significant differences in the distribution of allele and genotype frequencies for polymorphic markers rs2295080 and rs1883965 of the <italic>MTOR</italic> gene in the group of patients with pulmonary sarcoidosis and in the control group: (χ<sup>2</sup> = 0.196, d.f. = 1, <italic>p</italic> = 0.658 and χ<sup>2</sup> = 0.637, d.f. = 2, <italic>p</italic> = = 0.728) and (χ<sup>2</sup> = 0.034, d.f. = 1, <italic>p</italic> = 0.855 and χ<sup>2</sup> = 0.051, d.f. = 2, <italic>p</italic> = 0.975) respectively. Conclusion: аn increased level of expression of the MTOR gene in peripheral blood leukocytes of patients with pulmonary sarcoidosis may indicate the involvement of this gene in the pathogenesis of this disease. Polymorphic markers rs2295080 and rs1883965 of the <italic>MTOR</italic> gene are not associated with the risk of developing pulmonary sarcoidosis. Probably, an increase in the expression level of the MTOR gene in patients with pulmonary sarcoidosis is due to the development of inflammation.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45181324788016">Цель исследования – изучение ассоциации полиморфных вариантов rs2295080 и rs1883965 гена <italic>MTOR</italic> с риском развития саркоидоза легких. В исследование включено 253 человека (122 больных с диагнозом морфологически верифицированный саркоидоз с поражением легких (средний возраст – 41.00 ± 12.56 года) и 131 здоровый человек (контрольная группа) (средний возраст – 44.00 ± 14.23 года)). В исследование включены жители Республики Карелия. В исследуемых группах проанализировано распределение аллелей и генотипов полиморфных маркеров rs2295080 и rs1883965 гена <italic>MTOR</italic>. Генотипирование проводили с помощью ПЦР-ПДРФ анализа. Уровень транскриптов гена <italic>MTOR</italic> в лейкоцитах периферической крови (ЛПК) больных саркоидозом легких и здоровых людей оценивали с помощью ПЦР в режиме реального времени. Установлено статистически значимое повышение уровня экспрессии мРНК гена <italic>MTOR</italic> в ЛПК больных саркоидозом легких по сравнению с контрольной группой (<italic>р</italic> = 0.007). Отмечено снижение количества транскриптов указанного гена у пациентов, получающих терапию по сравнению с пациентами без терапии (<italic>p</italic> = 0.025). Cтатистически значимых различий в распределении частот аллелей и генотипов по полиморфным маркерам rs2295080 и rs1883965 гена <italic>MTOR</italic> в группе больных саркоидозом легких и в контрольной группе не установлено (χ<sup>2</sup> = 0.196, d.f. = 1, <italic>p</italic> = 0.658 и χ<sup>2</sup> = 0.637, d.f. = 2, <italic>p</italic> = 0.728) и (χ<sup>2</sup> = 0.034, d.f. = 1, <italic>p</italic> = = 0.855 и χ<sup>2</sup> = 0.051, d.f. = 2, <italic>p</italic> = 0.975) соответственно. Повышенный уровень экспрессии гена <italic>MTOR</italic> в лейкоцитах периферической крови больных саркоидозом легких может свидетельствовать о вовлечении указанного гена в патогенез данного заболевания. Полиморфные маркеры rs2295080 и rs1883965 гена <italic>MTOR</italic> не связаны с риском развития саркоидоза легких. Вероятно, повышение уровня экспрессии гена <italic>MTOR</italic> у больных саркоидозом легких обусловлено развитием воспаления.</p></trans-abstract><kwd-group xml:lang="en"><kwd><bold>s:</bold> <italic>Homo sapiens</italic></kwd><kwd>lung sarcoidosis</kwd><kwd>PCR-RFLP analysis</kwd><kwd><italic>MTOR</italic> gene</kwd><kwd>allelic polymorphism</kwd><kwd>expression.</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>саркоидоз легких</kwd><kwd>анализ ПЦР-ПДРФ</kwd><kwd>ген <italic>MTOR</italic></kwd><kwd>аллельный полиморфизм</kwd><kwd>экспрессия.</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Sarbassov D.D., Ali S.M., Kim D.H. et al.
