Thank you for the replies!

Kmeb thank you for sharing that information!

Kitt....yes they did dx my dad with CMT type 2 before his EMG/NCV and then there was no other reference to the type in his file ever after the EMG/NCV.

I gave the results of his NCV to my Neuro and he said based on the NCV test on my dad he would did not have type 2. He said the conduction velocities were indicitive of type 1 as well.

So, my dad's orginial dx was wrong according to my neuro.
