Abstract: Our data confirm the complexity of the genetic mechanism for the development of polyposis processes in patients with CPRS and indicate the necessity and importance of understanding complex gene interactions in the analysis of the development and clinical stage of the studied pathology. Material and methods. In accordance with the purpose of the study and to fulfill the assigned tasks, clinical studies were carried out in 140 patients with CPRS and with chronic rhinosinusitis, who were examined and treated at the ENT department of the multidisciplinary clinic of the Tashkent Medical Academy in 2017-2019. To study the diallelic polymorphism of the promoter regions of the genes of the studied interleukins, 50 healthy (no CPRS) donors, men and women, were examined. The average age of the examined donors was 51.3 ± 1.44 years. Conclusion. Analyzing the prevalence of genotypic variants of this polymorphism, we revealed a direct association of the C / C monogenotype of the A1188C rs3212227 polymorphism in the IL12B gene with the development of polyposis processes. The study of the distribution of genotypes showed that the homozygous genotype A / A was insignificant, almost 1.2 times more often found in group 1 (80.64%), while the frequency of detection of the heterozygous genotype A / C was insignificantly 1.1 times higher among patients with HRC 2 groups. The opposite situation could be observed in the study of the homozygous C / C genotype, which was not identified among all study groups.
