I would rather die at 35 of a genetic disease than live my entire life in the dystopia you describe. If we need a Butlerian Jihad, so be it. The fact that so many in this thread take the opposite attitude is terrifying to me. As far as I'm concerned, genetic technology represents an existential threat.
Yes, it would be fantastic if we could take the good without the evil, but it doesn't look like we're capable of doing so. Nevertheless the attitude of many is that technology (and not just genetic tech) will march on, and damn the consequences.

Historically, IQ tests were frequently used to justify racism and anti immigrant sentiment. IQ tests are strongly influenced by things like culture, so outgroups typically perform less well on them.
You need to be very skeptical as to the mental models being applied to something you cannot currently change, like your genes.
I have a genetic disorder. I was diagnosed late in life. So I had been managing my condition a long time without a diagnosis and getting a diagnosis empowered me to get a lot healthier. I have been endlessly crapped on for talking about that online because people are sure it cannot possibly be true. This is where identifying someone's genes gets very dangerous because our current mental models frame genes as inescapable destiny and such widespread belief tends to become self fulfilling prophecy by cutting you off from other options.
One night years ago, I dreamed of someone with chains around their neck that they could not remove from that end. The solution in the dream was to break the chains at the other end in order to get free, though it would not entirely free them of the burden of forever carrying these chains around. They at least we're no longer trapped.
I interpreted this dream to mean that the chains are my DNA, which I cannot escape. But I can change my diet and lifestyle. It isn't a cure, but it beats the hell out of what conventional medicine has to offer me.
It is the equivalent of saying "No, thanks, doc. I will keep my nuts and go get bigger undies." And I live in fear of the possibility that someday I shall be told that getting bigger undies is not a valid choice and I must submit to castration for my own good and the good of the larger community. (metaphorically speaking since I don't actually have any nuts)
Are you really comfortable with one company owning so many parts of patient care? I'm not.
What if a genetic disorder is determined by screening close family (parents, siblings, first cousins)? Could an insurance company reasonably determine that the trait exists within the family, thus block coverage as a "likely" pre-existing condition? Or worse, force a person to be tested if they want coverage?
What are the odds those consent forms will have blanket permissions? Allowing for fishing expeditions.
