Green List (high evidence)

Dominant CMT2P is usually characterized by relatively mild, slowly progressive axonal neuropathy, mainly involving lower limbs, with age of onset between the second and fifth decades of life. Variants tightly cluster in the C-terminal RING domain. This domain is crucial for the ubiquitination function of LRSAM1 and CMT mutations disrupt its function. Dominant negative effect postulated.

Note only one family reported with recessive inheritance, LoF postulated.
