Abstract
Schizophrenia is one of the most common mental disorders to severely affect human health worldwide. Single nucleotide polymorphisms (SNPs) within related genes are candidate susceptible factors for the disorder. Rs107822 within MiR219-1 and rs1625579 within MiR137 were genotyped in 589 cases and 622 controls to investigate the possible association between the loci and schizophrenia in a Chinese population. Our results showed significant association between rs107822 and the disorder in allele (C vs. T: adjusted ORÂ =Â 0.773, 95%CIÂ =Â 0.655-0.912), co-dominant (TC vs. TT: adjusted ORÂ =Â 0.734, 95%CIÂ =Â 0.571-0.943; CC vs. TT: adjusted ORÂ =Â 0.655, 95%CIÂ =Â 0.459-0.936), dominant (TCÂ +Â CC vs. TT: adjusted ORÂ =Â 0.707, 95%CIÂ =Â 0.559-0.895), and recessive (CC vs. TCÂ +Â TT: adjusted ORÂ =Â 0.724, 95%CIÂ =Â 0.524-0.999) models, respectively. Meanwhile, negative associations were also observed between rs107822 and the disorder in male and female subgroups, and genotype CC of the locus was significantly associated with a lower positive symptom score of PANSS compared to genotype TT carrier in the cases group. However, we didn't observe a significant association between rs1625579 and the disorder. These findings indicate that rs107822 within MiR219-1 might be involved in pathogenesis of schizophrenia and that genotypes TC, CC and allele C of the locus are protective factors for schizophrenia in a Chinese population.
