Sephinl showed beneficial effects on animal models of two protein-misfolding diseases, Charcot-Marie-tooth 1B (
CMT1B) and Amyotrophic lateral sclerosis (ALS), without any side effect in chronic treatments [42].
On the other hand, genetic testing provides an exact diagnosis of a specific subtype of CMT, including CMT1A,
CMT1B, CMT1C, CMT1D, CMT1F, CMTX1, CMT2A1, CMT2A2, CMT2B, and CMT2O.
Most MPZ mutations are associated with a
CMT1B phenotype, but in some cases, primary axonal involvement has been found.
Recent research has resulted in the development of rat and mouse forms of the most common type of CMT (CMT1A), the type that has to do with abnormalities in a gene on chromosome 17, and a mouse form of another form of CMT, the type that results from abnormalities in a gene on chromosome 1 (
CMT1B).
CMT1A disease, which is the most frequent type, is linked to chromosome 17p11.2 [4,5];
CMT1B disease, caused by the gene coding for the myelin protein [P.sub.0], is linked to 1822 [6-9].
