Opening up new horizons for psychiatric genetics in the Russian Federation: moving toward a national consortium.

We provide an overview of the recent achievements in psychiatric genetics research in the Russian Federation and present genotype-phenotype, population, epigenetic, cytogenetic, functional, ENIGMA, and pharmacogenetic studies, with an emphasis on genome-wide association studies. The genetic backgrounds of mental illnesses in the polyethnic and multicultural population of the Russian Federation are still understudied. Furthermore, genetic, genomic, and pharmacogenetic data from the Russian Federation are not adequately represented in the international scientific literature, are currently not available for meta-analyses and have never been compared with data from other populations.

The combined effect of CYP2D6 and DRD2 Taq1A polymorphisms on the antipsychotics daily doses and hospital stay duration in schizophrenia inpatients (observational naturalistic study).

Background: To assess the correlation between the antipsychotics (AP) mean daily doses, hospital stay duration and CYP2D6, DRD2 polymorphisms in naturalistic study.

Subjects And Methods: CYP2D6 polymorphisms *3, *4, *5, *6, *1XN and DRD2/ANKK1 Taq1A polymorphisms were genotyped in a cohort of 226 Caucasian schizophrenic inpatients. AP daily doses, hospital stay duration and AP treatment duration were taken from medical records.

Pharmacodynamic genetic polymorphisms affect adverse drug reactions of haloperidol in patients with alcohol-use disorder.

Background: Antipsychotic action of haloperidol is due to blockade of D receptors in the mesolimbic dopamine pathway, while the adverse drug reactions are associated with striatal D receptor blockade. Contradictory data concerning the effects of genetic polymorphisms of genes encoding these receptors and associated structures (catechol-O-methyltransferase [COMT], glycine transporter and gene encoding the density of D receptors on the neuronal membrane) are described.

Objective: The objectives of this study were to evaluate the correlation between DRD2, SLC6A3 (DAT) and COMT genetic polymorphisms and to investigate their effect on the development of adverse drug reactions in patients with alcohol-use disorder who received haloperidol.
