(for information purposes)
Had an appointment at the hospital today to see the lead nurse to discuss family history (looks like I am the first with my problem) and as my cardiologist still can't work out why I had heart failure I have been referred for genetic testing.
She explained there are three possible outcomes 1) there is no genetic problem 2) this is 3) there is a grey area where they don't know. She advised if it is 3 then I can with my permission (granted) to be tested again in 5 years time taking into account any further medical advances.
I am all for it, particularly if my genes can be used (even in a tiny way) to advance the medics knowledge and secondly as it might have a knock on effect to my sister and her children (if she has that particular gene), which will give them plenty of time to hopefully do something about it.
I actually find it very interesting and exciting (but then I am slightly mad).
