Phenotypic realization of single nucleotide polymorphism rs950880 of IL1RL1 gene in healthy inhabitants of Vinnytsia region.

Abstract

Annotation. Soluble growth stimulating factor (sST2) is a new biomarker that has recently been used quite successfully in cardiology. However, the possible genetic component of peptide production has not been sufficiently studied. The aim of the study was to assess the plasma level of sST2 and other aspects of the phenotypic implementation of single nucleotide polymorphism (SNP) rs950880 of the IL1RL1 gene in men without cardiovascular disease in the Podillia region, Ukraine. 70 men who met the criteria for inclusion/non-inclusion in the study were examined, general clinical, laboratory and instrumental methods were used. Genotyping of SNP rs950880 variants of the IL1RL1 gene was performed using an allele-specific polymerase chain reaction, the concentration of sST2 in blood was investigated using the method of enzyme-linked immunosorbent assay. Mathematical processing of the obtained results was performed using the standard statistical package Statistica 12.0. The mean concentration of sST2 in the plasma of men without signs of cardiovascular disease is 22.14±0.86 ng/ml. It was found that among men without cardiovascular diseases, residents of Podillia, the most common carriers of the C allele and variants of CC and CA SNP rs950880 of the IL1RL1 gene, carriers of variant AA are four times less common (p<0.05). It was determined that the main phenotypic feature of SNP rs950880 of the IL1RL1 gene is a higher plasma level of sST2 in CC homozygotes (23.34±1.22 ng/ml) compared with AA homozygotes (18.13±0.85 ng/ml, p<0,01). The obtained results will be the basis for further studies of the phenotypic implementation of the SNP rs950880 gene of the IL1RL1 gene in patients with cardiovascular pathology, in particular, with essential hypertension.
