I'm pretty confident that I answered every question accurately and that no answers would have changed based on anything I could have learned from a genetic test. Health insurers were really bad about "prior conditions" before Obamacare. I think life insurance has always been more tightly regulated. FWIW, my policy says the insurer can only challenge the application within the first two years.
