Objective. To study the intergenic interactions of gene markers for thrombophilia, impairments in homocysteine metabolism and blood pressure regulators in women with bad obstetric history. Subject and methods. The investigation enrolled two groups of women. A study group included 200 women with bad obstetric history (spontaneous abortions, preterm births, and non-developing pregnancy). A control group consisted of 200 women with good obstetric history. Molecular genetic testing of 21 allelic polymorphisms in the genes (MTHFR, MTR, MTRR, FGB, F2, F5, F7, F13, ITGA2, ITGB3, PAI-1, ADD1, AGT, AGTR1, AGTR2, CYP, GNB, and NOS3) was carried out. Results. Univariate analysis revealed no statistically significant differences in the frequency of alternative genotypes in the study genes. However, the higher frequency of a definite combination of genotypes (AGT 704CC, NOS3 894GT, and MTRR 66AG) was found in the bad obstetric history group. Conclusion. The definite combination of the genes in obstetric complication susceptibility genes (the hemostatic factors, homocysteine metabolism, blood pressure control and vascular tone control genes) can supposedly affect the lability of compensatory and adaptive responses.
