Some molecular genetic markers of the severity of myocardial infarction

Abstract

Purpose of the study : the aim of this work is to assess the association of 7 SNPs (rs499818 of the PHACTR1 gene, rs619203 of the ROS1 gene, rs10757278 (xr. 9), rs1376251 of the TAS2R50 gene, rs2549513 (xp. 16), rs4804611 of the ZNF627 gene and rs17465637 гена MIA3 ) with the severity of myocardial infarction. M aterials and methods. Three samples were taken as objects of research. A population sample of patients with non-fatal MI (200 people: men – 129, women – 71), a sample of participants in the HAPIEE project with developed MI during the study (94 people: men – 56, women – 38). A sample of patients with myocardial infarction admitted to the intensive care unit of the city clinical hospital № 1. The sample size was 159 people (112 men, 47 women). The following SNPs were taken into the study: rs499818 (xp. 6), rs619203 of the ROS1 gene, rs10757278 (xr. 9), rs1376251 of the TAS2R50 gene, rs2549513 (xr. 16), rs4804611 of the ZNF627 gene and rs174653. To assess the association of SNP and the severity of the disease, we compared a population sample of patients with non-fatal MI versus a joint group from a sample of HAPIEE project participants with developed MI during the study, and a sample of MI patients admitted to the intensive care unit of City Clinical Hospital No 1. Results. For two SNPs, statistically significant differences in genotype frequencies were obtained: rs10757278 AA vs AG + GG OR = 0.61 CI 0.39–0.94; p = 0.027 and rs619203 of the ROS1 gene in a group of men for genotype GG vs CG + CCOS = 0.59 CI 0.37–0.94; p = 0.033. C onclusions. The associations of seven SNPs were studied, which, according to international studies, are associated with the risk of development, poor prognosis and the severity of myocardial infarction in the population of residents of the city of Novosibirsk. Two SNPs (rs10757278 and rs619203) were identified, which are associated with the severity of myocardial infarction.
