Thanks for the info, Kitt, and for your interest. Yes, my negative result for the MFN2 test means that I don't have CMT2A2. A skin biopsy, and nerve conduction testing, indicates that my neuropathy is axonal.

Fascinating info on HNPP. There are some similarities between the symptoms listed and my experience. However, HNPP is "primarily demylenating" and my nerve loss is axonal. I also don't experience any muscle involvement to speak of (though that's variable in HNPP). Still, the info has spawned a new thread of research for me and I'll bring it up with my neurologist the next time I see him.

But I don't really want to hijack this thread... On my 'to do' list is getting all my symptoms and test results together and starting a thread for a review by all the fine folks who hang out here. Right now, my diagnosis is "ideopathic axonal peripheral neuropathy" and I'd like to make the "ideopathic" part go away. Well, I'd like to make all of it go away... Thanks again, Kitt.
