Charcot-Marie-Tooth disease type 2.

No unique genes have yet been found for CMT2, but both Cx32 and P0 appear to contribute to the phenotype. Not surprisingly, CMT2 is likely to display much more genetic heterogeneity than CMT1. However, it is also likely continue to challenge previous concepts on classification and relationship of traditional inherited phenotypes in neurology. Future work on CMT2 should produce insight not only into the cellular interactions of the peripheral nerve especially Schwann cell and axon relationships, but also into idiopathic neuropathy.
