Maybe too far fetched? Company sells/loses data, insurance companies use data to deny coverage, or deem claims as pre-existing.

Can an insurance company deny claim based on your DNA? They deny claims for pre-existing condition that you hid from the, which would be the wrong thing to do on your part. They cannot deny claim based on pre existing disposition. Practically everyone is predisposed for getting cancer by merely being human, you might even have cancerous cells in your body right now, that you body will destroy in a couple of minutes.

Health insurance in the US can't- it's protected by a law called GINA. Life insurance, however, can use DNA information.
