Aim. Functional polymorphism ER22/23EK glucocorticoid receptor leads to reduction of its resistance and to increase in its sensitivity to the glucocorticoid that regulate the functioning of the axis hypothalamus - pituitary - adrenal glands. Disturbances in the regulation of this axis are observed in patients with psychiatric disorders. The aim of this study was to demonstrate the association ER22/23EK polymorphism with bipolar disorder and major depressive disorders. Methods. In the study 144 patients with unipolar disorders and 479 patients with bipolar disorder were included. Patients were diagnosed by two psychiatrists on the basis of medical records and interview based on SCID criteria (Structured Clinical Interview for DSM Disorders). The control group comprised 595 healthy subjects. As the research material peripheral blood was used, from which DNA was obtained. Genotyping was performed using PCR RFLP method. Results. No association of ER22/23EK polymorphism with unipolar disorder or with bipolar disorder was found. GA genotype was not observed in any of the subjects. Conclusion. ER22/23EK functional polymorphism of the glucocorticoid receptor gene is not associated with unipolar and bipolar disorder.
