It can be very expensive if you have to test for all of the types of CMT that they can test for. Not sure if insurance covers it or not.

If indeed your father's brother turns out to have CMT then your father would have it but not noticeable symptoms. CMT does not skip a generation. That in turn would be where you would get it from if indeed you do have CMT. Keep in mind that I'm not suggesting that anyone in your family has CMT. Hope this helps.
