Наведено результати визначення 10 поліморфізмів генів системи матриксного Gla-протеїну (ген MGP-T-138 →С (rs1800802), G-7 →A (rs1800801), Thr 83 →Ala (rs4236); ген VDR-FokI (rs2228570), BsmI (rs1544410), ApaI (rs7975232), TaqI (rs731236), ген GGCX-Arg 325 →Gln (rs699664), ген VKORС1-T 2255 →C (rs2359612), ген BMP-2-Ser 37 →Ala (rs2273073)) у 170 хворих з ішемічним атеротромботичним інсультом (ІАТІ) і 124 здорових індивідуумів (контрольна група). Встановлено, що існує зв'язок між ІАТІ і поліморфними варіантами генів MGP (G-7 →A) та VKORC1 (Т 2255 →С). Ризик розвитку ІАТІ у носіїв мінорного алеля A/A (G-7 →A-поліморфізм) у 2,6 вищий, ніж у носіїв основного алеля (G/A+G/G), а у осіб з генотипом С/С (Т 2255 →С-поліморфізм) у 2,2 раза більший, ніж у гомозигот за основним алелем. Збіг у пацієнтів генотипів T/C і G/G, C/C і G/A, а також генотипу A/A (G-7 →Aполіморфізм) із будь-яким з генотипів за Т 2255 →С-поліморфізмом збільшує ризик розвитку ІАТІ.

Coronary artery disease (CAD) is one of the leading causes of death in Europe. It is known that atherosclerosis is the primary risk factor of CAD development. MMP-9 is involved in all stages of atherosclerosis and thus may contribute to CAD emergence. To investigate the influence of MMP-9 on the (CAD) development 25 patients with intact coronary arteries (CA), 40 patients with acute coronary syndrome (ACS), and 63 patients with chronic coronary syndrome (CCS) were enrolled in the study. Real-time PCR was carried out for genotyping on the rs17567-polymorphic locus, and ELISA study was performed to measure the MMP-9 plasma concentration. It was found the lower risk of MI occurrence for AG-carriers ( P a = 0.023 ; ORa = 0.299, 95% CI = 0.106–0.848) in Ukrainian population.

⎯The present study was performed to investigate whether common single-nucleotide polymorphism K121Q (rs1044498) of the ENPP1 gene is associated with the known risk factors of atherosclerosis (overweight, dyslipoproteinemia, hypertension, diabetes, smoking, and hypercoagulability) in persons with acute coronary syndrome. Venous blood of 118 patients was genotyped for the polymorphism by PCR and restriction fragment length polymorphism method. In patients divided into two subgroups according to their genotype (KK and KQ + QQ), the statistically significant differences were revealed only for plasma LDL-cholesterol level and fibrinolytic activity. The carriers of minor allele (KQ + QQ) had lower LDL-cholesterol concentration and the time of fibrinolysis than the major allele homozygotes (KK). The division of patients into subgroups according to presence or absence of some risk factors for atherosclerosis showed no statistically significant differences between K121Q genotype distributions for any of the comparison.

The aim: To study the association of the polymorphisms VDR gene with high blood pressure in stroke patients in the Ukrainian population. Materials and methods: Venous blood of 170 patients with atherothrombotic ischemic stroke (AIS) and 124 healthy individuals (control group) was used for genotyping. Four polymorphisms (FokI, BsmI, ApaI, TaqI) of gene VDR were examined with PCR-RFLP methodology. Statistical analysis was performed by using SPSS-17.0 program. Results: The correlation of genotypes of polymorphic variants of FokI, BsmI, ApaI and TaqI of the VDR gene with the development of ischemic atherothrombotic stroke in individuals with normal and high blood pressure was detected. Statistical analysis of the obtained data revealed that among carriers of genotypes F/F, b/b, a/a, a/A, and T/T patients with AI have statistically significantly higher incidence of hypertension than patients in the control group. Conclusions: It was found that persons with genotypes F/F, b/b, a/a, a/A, and T/T showed a statistically significant relationship between hypertension and the development of IAS. The application of logistic regression has made it possible to establish that the risk of IAS in people with normal blood pressure and genotype F/f is 3.2 times higher than in normotensive homozygotes for the F-allele.
