Hi,
I had genetics testing done last month. I am still waiting on the results.

I had it done for the same reasons that you are suggesting. (I have two aneurysms (4.4 and 4.6).) I also was told by my cardiologist that if there was a genetic component, it could impact "when" I have surgery. No one mentioned insurance issues, but I move to Medicare in 2026 and no longer carry life insurance. If you decide to do it, the tests are expensive, so you will want to ensure your insurance covers it. My cardiologist didn't push the test aggressively on me, and she warned me that genetic testing often turns up nothing.
