Contact ROS1, TAS2R50, ZNF627, MIAF3 genes and 16q23.1, 6p24, 9p21 chromosomal regions with myocardial infarction in Caucasians of Novosibirsk in two age groups
Aim: Investigate relations of 8 SNPs with myocardial infarction in groups of up to 55 years and after 55 years. Methods: The group of patients with myocardial infarction, arrived in the intensive care unit City Clinical Hospital № 1 (2009-2010 gg.) 160 people (113 men and 47 women). The control group was formed based on the sample of population 45-69 year old residents of the October and the Kirov district of Novosibirsk (9.400 people), which was collected by Institute of Internal Medicine SB RAMS during the work on the international project HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe). It included 420 people with no signs of myocardial infarction (men 270, women 150). Genomic DNA was isolated from venous blood by phenol-chloroform extraction. SNP of gene were tested by RT-PCR according to the protocol of the manufacturer (TaqMan Probes, Applied Biosystems, USA) on the device ABI 7900HT. In a study following SNPs were taken: rs499818, rs619203, rs1333049, rs1376251, rs2549513, rs4804611, rs17465637. Results: For rs1333049 were shown an association with MI: SS OR = 2.05 (95 % CI 1.35-3.12 p = 0.001, CC vs CT + TT) and PT OR = 0.59 (95 % CI 0.37-0.93; p = 0.023; CT vs CC + TT) in the group. In both age groups, an association has been confirmed: SS OR = 2.92 (95 % CI 1.39-6.16; p = 0.006; CC vs CT + TT) for junior and SS OR = 1.77 (95 % CI 1.05-2.97; p = 0.035; CC vs CT + TT) and senior groups. For rs4804611 shows a predisposing role in relation to MI AA OR = 1.63 (95 % CI, 1.03-2.45; P = 0.04; AA vs AG + GG) in the older age group, for the remaining SNPs statistically valid data has been received. Conclusions: Thus in this study were confirmed by rs1333049 association (hr. 9) with myocardial infarction, regardless of age, as well as shows the association of rs4804611 in the group over 55 years.
