PREVALENCE OF POLYMORPHISM OF THE IL1RL1 GENE (rs950880) AMONG RESIDENTS OF THE PODILSK REGION OF UKRAINE

Abstract

The study of the "genetic architecture" of essential hypertension (EH) is becoming increasingly relevant, in particular, the study of the genetic component of the production of peptides, which are used as biomarkers in cardiology. Soluble ST2 of the interleukin-1 receptor family is a promising marker of myocardial remodeling. The genetic basis of ST2 production - SNP rs950880 of the IL1RL1 gene requires a detailed analysis. The aim of the study was to study the prevalence of SNR rs950880 polymorphic variants of the IL1RL1 gene among men living in the Podilsk region of Ukraine with essential hypertension (EH) of varying severity. Material and methods. In the course of the work, 170 men aged 40 to 60 years were examined: 70 without cardiovascular diseases and 100 patients with EH of varying severity (50 with asymptomatic EH (AEH) and 50 patients with EG complicated by CHF II A stage (EH+CHF)). Determination of polymorphism rs950880 of IL1RL1 gene was performed using polymerase chain reaction (PCR). The statistical analysis of the research results included the calculation of the odds ratio, the analysis of conjugation tables. Results. It was established that among residents of the Podilsk region of Ukraine, the SNP variant rs950880 of the IL1RL1 gene, which has the C allele, is the most common: among men without cardiovascular diseases, carriers of the CC and AC variants dominate (45.72% and 42.86%, respectively), the prevalence is similar SNP rs950880 and among patients with EH of different severity (among patients with EH homozygous CC 42.00%, heterozygous AC - 46.00%; in the group EH+CHF - 38.00% and 48.00%, respectively). The AA variant is the least common in all groups (11.42% in the control group, 12.00% among patients with AEH, 14.00% in the EH+CHF group). Conclusions. According to the frequency distribution of the rs950880 polymorphism of the IL1RL1 gene, men with EH of different severity do not reliably differ from the general population of residents of the Podilsk region. Carriership of the investigated polymorphism is not associated with an increased risk of developing EH or complications of CHF. Variability is observed in the frequency distribution of SNR rs950880 IL1RL1 gene alleles in different populations.
