CMT classification system
CMT classification uses numbers (1, 2, 3, 4, 6) to depict type and letters (A, B, C … ) to represent a subgroup within that type. An exception is type X (CMTX), which is passed down by X-linked inheritance.
The most common types are:
- CMT1: Demyelinating neuropathies (the protective layer around the nerve, known as the myelin sheath, is damaged, so the nerve signals transmit very slowly) Read more…
- CMT2: Axonal neuropathies (the axon is damaged, which leads to loss of the nerve signal) Read more…
- CMTX: X-linked gene inheritance
- CMT4: Recessive inheritance
