Several lines of evidence suggest that suicide may have, in part, a genetic predisposition. In this study, we identified a family with high rates of suicidal behavior and assessed brain gene expression levels in the proband. A neuronally-expressed solute carrier for glutamine (Sodium-coupled neutral amino acid transporter 1 (SNAT1), also known as solute(More)
OBJECTIVE There is substantial evidence suggesting that suicide aggregates in families. However, the extent of overlap between the liability to suicide and psychiatric disorders, particularly major depressive disorder, remains an important issue. Similarly, factors that account for the familial transmission of suicidal behavior remain unclear. Thus, through(More)
BACKGROUND Suicidal behaviour aggregates in families, and the hypothalamic-pituitary-adrenal (HPA) axis and noradrenergic dysregulation may play a role in suicide risk. It is unclear whether stress dysregulation is a heritable trait of suicide or how it might increase risk. We investigated stress reactivity of the autonomic nervous system and the HPA axis(More)
