Access through your institution Buy or subscribe Charcot-Marie-Tooth disease 1A (CMT1A) is an inherited neuropathy caused by duplication of the gene encoding peripheral myelin protein 22

(PMP22). In this study, _PMP22_ duplication in rodents caused defects in Schwann cell differentiation in early postnatal development, which persisted into adulthood. This abnormal Schwann

cell phenotype could be rescued by axonal overexpression of neuregulin-1 (NRG1) or by treatment with soluble NRG1 in early postnatal stages. These data suggest that there is a temporal

window for correct Schwann cell differentiation that is vital to prevent the neuropathy observed in CMT1A. This is a preview of subscription content, access via your institution ACCESS
