The Anatomy and Cell Biology of Peripheral Myelin Protein-22.

The gain of function phenotypes exhibited by the heterozygous Tr, Tr-J, and CMT1A mutations indicate that these mutations interfere with more than the function of a single PMP22 allele. The identification of proteins that interact with PMP22 and that are sensitive both to stoichiometry and the effects of the mutations could provide important leads to a unified hypothesis to explain the riddle of the PMP22-related neuropathies.
