Having a close family member affected by a mental illness is the largest known risk factor, to date.

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?
