This isn't too similar to your situation, but just in case it helps... When I was in the U.S. I went to go get genetic testing for a disease. Before the clinic allowed me to test they went over things to consider, and one was that although employers and health insurance companies now legally can't discriminate against genetic predisposition, life insurance companies still can. The clinic wasn't sure about the policy in the UK, but their standard advice was to take out a policy prior to the testing and then cancel it later if I wanted to. My husband and I took out a life insurance policy prior to the testing, and sure enough one of the questions (even in the UK) was if I had undergone genetic testing for a disease, which we were truthfully able to say no to. Luckily the results were negative so we won't need to worry about it in the future, but life insurance companies are allowed to be incredibly selective, so my advice is to shop around at a few companies and perhaps go through an agent. There are a lot of comparison sites out there, and that might be the best place to start. One company not working out definitely shouldn't bring you down too much until you look at your other options. Good luck!
