  • SUMMARY. G-7A polymorphism (rs1800801) of matrix Gla protein (MGP) gene in 170 patients with ischemic atherothrombotic stroke (IATS) and in 124 persons of the control group was determined. It was shown that in patients with IATS the distribution of the major allele homozygotes, heterozygotes and minor allele homozygotes was 35,9; 48,8; 15,3 % (in control – 43,5; 50,0; 6,5 %, P = 0,051 by χ2-test). Significant differences in the distribution of genotypes were revealed only in women (P = 0,022). Odds ratio for minor allele homozygotes (A/A) versus major allele carriers (G/A+G/G) was 2,618 (P = 0,023), while in women it was equal to 6,645 (P = 0,015). In patients with A/A genotype the values of blood coagulation parameters (prothrombin time) indicated increased predisposition to hypercoagulability. The results obtained suggest that the A/A-variant of MGP gene is associated with an increased risk of IATS in female persons of the Ukrainian population and may be related to blood hypercoagulability and thrombi formation.
