Abstract
The MIR137 gene encodes microRNA-137 (miR-137), which is a brain-enriched miR that is highly expressed in various brain regions. miR-137 has been identified as a modulator of processes involved in the pathogenesis of neuropsychiatric disorders. Functional polymorphism of variable number of tandem repeats (VNTR) rs58335419 was found in the regulatory region of the MIR137 gene. It is associated with a change in the expression of miR-137 and, as a result, with an increased risk of developing psychopathologies, including schizophrenia. In this study, we for the first time have analyzed the distribution of frequencies of alleles and genotypes of MIR137 VNTR in a large sample from the Russian population. The association of VNTR with the risk of schizophrenia has been studied. It was found that the presence of VNTR alleles with more than three repeats, as well as a genotype homozygous for such alleles, is associated with an increased risk of developing schizophrenia (OR = 1.4, 95% CI: 1.01–1.95).
期刊介绍：
Russian Journal of Genetics is a journal intended to make significant contribution to the development of genetics. The journal publishes reviews and experimental papers in the areas of theoretical and applied genetics. It presents fundamental research on genetic processes at molecular, cell, organism, and population levels, including problems of the conservation and rational management of genetic resources and the functional genomics, evolutionary genomics and medical genetics.
