Association of polymorphism of CYP2D6 and CYP2C9 genes encoding P-450 proteins of cytochrome with arterial hypertension
Saratov Journal of Medical Scientific Research. 2012. Vol. 8, № 4. P. 933–937.
Abstract Gene polymorphisms of cytochrome P-450 CYP2 encoding proteins of cytochrome P-450 are essential forantihy-pertensive drugs metabolism. Purpose: We study the associations of functionally defective allele variants of CYP2D6 gene and CYP2C9 gene with the degree of arterial hypertension (AH). Materials and methods: Samples of DNA of leukocytes of blood of 150 patients with AH without the associated clinical conditions (56% of women) at the age of 20-59 years have been investigated. For the study of polymorphism of genes the pharmacogenetic biochip developed in the Institute of Molecular Biology n.a. V. A. Engelgardt has been used. Comparison of frequencies of occurrence of signs has been carried out on the basis of chi-square criterion. Results: It has been revealed that homozygotes by mutant A1075C, C430T alleles of CYP2C9gene and G1934A of CYP2D6 gene have been significantly more common among patients with hypertension III (p=0.01). Conclusion: The research works on genes of system of P-450 cytochrome have important clinical value for rationalization of pharmacotherapy of hypertension. The increased frequency of occurrence of mutant allele of CYP2D6 and CYP2C9 genes in patients with hypertension III requires special attention to the problem of efficiency and safety of application of hypotensive drugs for the patients.
