Abstract:

OBJECTIVE

To check the association of genetic polymorphisms rs6280 of the DRD3 gene, rs4680 of the COMT gene, rs7322347 of the HTR2A gene with schizophrenia.

MATERIAL AND METHODS

The sample included 300 inpatients with paranoid schizophrenia. Inclusion criteria: age 18—50 years, established diagnosis «Schizophrenia, paranoid form», duration of psychiatric disorders not less than 5 years. The healthy control group consisted of 290 subjects. The association between polymorphisms and the study groups was assessed by logistic regression.

RESULTS

The CC genotype of the rs6280 polymorphism is associated with schizophrenia (OR 3.37 (1.50; 8.03)). The TT genotype of the rs7322347 polymorphism is associated with controls (OR 1.83 (1.25; 2.68)).

CONCLUSION

These analyses confirmed the hypothesis that the genetic polymorphisms rs7322347 of the HTR2A gene (p=0.006) and rs6280 of the DRD3 gene (p=0.004) were associated with the disease. The hypothesis of an association of the rs4680 polymorphism of the COMT gene could not be confirmed.
