PURPOSE OF REVIEW The aim is to specify the genetic causes of dominantly and recessively inherited axonal forms of Charcot-Marie-Tooth disease (CMT) and review the biological basis for these disorders. RECENT FINDINGS More than 10 genes that cause axonal CMT have been identified over the past decade. Many of these genes express proteins that are(More)
Mutations in myelin protein zero (MPZ) cause Charcot-Marie-Tooth disease type 1B. Many dominant MPZ mutations, including R98C, present as infantile onset dysmyelinating neuropathies. We have generated an R98C 'knock-in' mouse model of Charcot-Marie-Tooth type 1B, where a mutation encoding R98C was targeted to the mouse Mpz gene. Both heterozygous (R98C/+)(More)
Charcot-Marie-Tooth disease type 1B is caused by mutations in myelin protein zero. R98C mice, an authentic model of early onset Charcot-Marie-Tooth disease type 1B, develop neuropathy in part because the misfolded mutant myelin protein zero is retained in the endoplasmic reticulum where it activates the unfolded protein response. Because oral curcumin, a(More)
CMT1B is the second most frequent autosomal dominant inherited neuropathy and is caused by assorted mutations of the myelin protein zero (MPZ) gene. MPZ mutations cause neuropathy gain of function mechanisms that are largely independent MPZs normal role of mediating myelin compaction. Whether there are only a few or multiple pathogenic mechanisms that cause(More)
