Do BDD and depression have the same genetic roots?

Depression also runs in families and we know a lot more about the genetics of depression, so that we know it's not just an environmental effect, that it does happen in twins that are raised apart, for example. But the story is also very complex, with depression, that, again, there's no one gene that caused the depression, but there are probably a gene or genes that predispose somebody; make it more likely they'll have depression, if they have some other stress in their life, for example.
