In a rare display of common sense, the US Congress has put through laws making it illegal to discriminate on DNA – ie. insurance companies can’t raise their rates or refuse to cover someone who has had DNA testing and has had results indicating a risk for certain genetic diseases. Not only is it none of the insurance companies business, but this means these tests can’t be forced on you by employers and that hopefully more people will get these tests done, allowing more scientific data to come out of it.
