It's been interesting to see genetics slowly get expanded to help understand more conditions... Just like cancer isn't caused by one thing, many of the common "psych" diseases aren't caused by one thing. The more obvious candidates for a strong genetic component are disorders like depression, alcoholism, and ADHD; but I'm sure this will be broadened into other mental health areas like diet, obesity and stress management. There is still a strong environmental component, so I'm not trying to say that genetics is everything, but it's still important.
