I had genetic testing for cardiac issues and a very strong family history of Alzheimer’s. I am quite a bit older than you. What my brother and I decided was to have the testing and if positive (his is positive, mine is pending) to treat our kids as though it is positive in them as well, not getting them tested. This does not really relate to you I know. But the reason is, once a genetic test is positive it must be reported on life insurance applications and such. At only 25, you may not have life insurance. I would discuss with your insurance broker and if you can afford life insurance, and foresee needing it in your future (plans for kids), get it now before having the testing.

That having been said, if you need genetic testing, you need it.
