It is unlikely that a single gene is involved. It is likely that a genetic predisposition interacts with stressful events to create the disorder. A gene called 5-HTT comes in two forms, a long and a short form. The short form appears to be related to depression. Genes may exert their effects by affecting levels of serotonin and other neurotransmitters or by affecting production of cortisol. |
