in research stages as there is always research going on. There are many, many types of CMT. They are finding more all of the time. Most all of the types are inherited. Sometimes there can be a spontaneous mutation but it is rare.

Symptoms of CMT can be evident when you are young, old, or in-between. Or they might not be that evident but a person can still pass it on. Symptoms vary greatly even within the same family. There is DNA blood testing for many types of CMT but not all of them. Just because you do not test positive for it does not mean that you don't have it. It can mean that you have a type that they cannot test for. And DNA blood testing is very expensive especially if you have to do the whole panel of tests.

CMT is often misdiagnosed even today as something else such as polio, Fredrick's Ataxia, MS, and the like. It is very important to be seeing a neurologist who is an expert when it comes to CMT.
