BIG BIG slippery slope here and I'm glad you raised it. When it comes to insurance, "plausible deniability" is the best policy because they can deny coverage for so many petty reasons. I believe Obamacare is supposed to address some of these issues, but not certain. Nevertheless, insurance companies would certainly move for genetic sequencing prior to issuing a policy at some point in the future, it just makes too much business sense for them. Which is why health insurance should be non-profit - to take away the profit motive that corrupts health care.
