    Abstract:
    AIMS: The glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) play important roles in the hypothalamic-pituitary-adrenal axis and stress regulation. The current study aimed to address the genetic association and gene-gene interactions between GR and MR gene polymorphisms and aggressive behavior. METHODS: A haplotype-based, case-control study was designed to examine the association between human MR and GR genes and aggressive behaviors, including robbery and intentional interpersonal injury, in a central south Chinese Han population. Eight well-studied polymorphisms of the MR gene (rs2070951, rs2871, rs5522, and rs5525) and the GR gene (rs10482605, rs6190, rs1800445, and rs6196) were genotyped using SNaPshot. RESULTS: The MR and GR gene polymorphisms were not associated with aggressive behaviors, including in robbery and intentional interpersonal injury subgroups (p > 0.05). The frequency of haplotype TAAT of GR was significantly higher in the control group than that in the case group (p = 0.004, padj = 0.02). In addition, a two-way interaction between GR rs1800445 and MR rs2070951 and aggressive behavior was also found (p = 0.01). CONCLUSIONS: The haplotype TAAT of GR might be a protective factor against aggressive behavior, while gene-gene interactions between GR rs1800445 and MR rs2070951 might be a risk factor for aggressive behavior in the Central South Chinese Han population.
