This is good info for those of us who have always realized it runs in families. Finally nice to have some proof to work with.

Yes, I always knew that serotonin/tryptophan played an important role in depression. I worked in a health food store and the people that took L-Tryptophan swore by it.

Yes. My mother is manic-depressive, her mother and sister were also, and now so is my daughter. When I was youmg, the psychiatrists used to tell us that mommy was that way because she suffered trauma as a child. It was complete bullshit.

I am hopeful that this will lead to even more beneficial treatments for my daughter.

There has been strong epidemiological evidence of the inheritability of the tendency toward depression for at least forty years. In populations all over the world.

I for one don't think one gene is involved. Depression is too variable a condition for one gene to be responsible.

I agree.
