Inflammatory demyelination in a patient with CMT1A

Muscle Nerve. 2003 Sep;28(3):373-6. doi: 10.1002/mus.10404.

Abstract

We report a case of Charcot-Marie-Tooth disease (CMT), with identified PMP22 gene duplication (CMT type 1A), and with evidence of an inflammatory demyelinating process superimposed on the course of the chronic genetic disease. Macrophage-associated demyelination was observed on the peripheral nerve biopsy. This observation supports some experimental data from the literature and shows that there may be a genetic susceptibility to inflammatory demyelinating processes in certain CMT kindreds.
