Introduction. Atrial fibrillation is a heart rhythm disorder. Apixaban is a direct-acting anticoagulant whose mechanism of
action is to inhibit the activity of clotting factor Xa. The literature shows that polymorphisms of the ABCB1 gene are the most
common genetic variants that contribute to the change in peak and trough levels of drugs with a proven clinical effect.
Purpose of the study. Study of the effect of ABCB1 gene polymorphisms on apixaban concentrations in patients with
atrial fibrillation in the Kazakh population.
Methods. Genomic DNA was isolated from peripheral blood samples using a commercial Thermo Scientific GeneJET
Whole Blood Genomic DNA Purification Mini Kit (Thermo Fisher Scientific) according to the manufacturer's instructions. DNA
concentration was measured on a Nanodrop 1000 spectrophotometer. SNP genotyping was performed using TaqMan
technology.
Results. In this study, no statistically significant differences were found in peak or minimum concentrations of apixaban
in blood plasma with different genotypes of ABCB1 gene polymorphisms (rs4148738, rs1045642, rs2032582, rs1128503) in
the Kazakh population.
Conclusions: Analysis of the influence of genetic factors on the activity of enzymes involved in the metabolism of the
drug will help expand the possibilities of personalized medicine for individualizing treatment. It is necessary to conduct more
extensive studies to study the effect of the carriage of ABCB1 polymorphisms on the metabolism of apixaban in various
ethnic populations.
