Do genetics affect depression?
Depression is known to run in families, suggesting that genetic factors contribute to the risk of developing this disease. However, research into the genetics of depression is in its early stages, and very little is known for certain about the genetic basis of the disease.
What genes are associated with depression?
The serotonin transporter gene and genes involved in the serotonergic system are candidate genes for susceptibility to depression given that many antidepressant medications act on these systems. Several studies have implicated the serotonin transporter gene (SLC6A4) in MDD [17–19].
