Myelin abnormality in Charcot-Marie-Tooth type 4J recapitulates features of acquired demyelination.

Abstract

Charcot-Marie-Tooth type 4J (CMT4J) is a rare autosomal recessive neuropathy caused by mutations in FIG4 that result in loss of FIG4 protein. This study investigates the natural history and mechanisms of segmental demyelination in CMT4J.
