Abstract
Genetic association studies have linked suicide behavior with genes encoding transporters of monoamine. Variants in the vesicular monoamine transporter 1 (VMAT1) have been previously shown to be associated with several psychiatric disorders including schizophrenia and bipolar disorder. However, their association with suicide behavior has not been explored. In the present study, we genotyped three single-nucleotide polymorphisms (rs2270637, rs1390938, and rs2279709) within this gene in 100 individuals who attempted suicide, 236 suicide victims, and 300 control subjects without any history of psychiatric disorders or suicide ideation. We demonstrated no difference in genotype, allele, or haplotype frequencies of theses single-nucleotide polymorphisms between the study groups. Consequently, contribution of VMAT1 in risk of psychiatric disorders might be independent of suicide behavior. Future studies with larger sample sizes are needed to confirm our results.
