Types of Charcot-Marie-Tooth
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. Below are the most common types of Charcot-Marie-Tooth disease.
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
HNPP
- Hereditary Neuropathy with Liability to Pressure Palsies
