--I've found that many physicians, even some neurologists, think that hereditary neuropathy and Charcot-Marie-Tooth are synonymous, but in reality there are numerous variation of hereditary neuropathies and myopathies, of which CMT in its various forms is only one permuatation (although it does seem to be the most common one, and more understood than many of the others).

There are variants of CMT, there are numerous kinds of hereditary sensory and autonomic neuropathies (HSAN), and a batch of hereditary motor/sensory neuropathies that are not under the CMT rubric, as well as numerous hereditary neuromuscular syndromes without widespread sensory involvement. If one looks at the ever-expanding listings at the Washington University Neuromuscular website:

one could be excused for thinking that each individual case is a new entity unto him/herself.

The likelihood is that as the human genome continues to be studied, even more of these conditions will be identified, and many will be associated with effects and consequences beyond the neuromuscular . . .
