We reported one patient with Charcot-Marie-Tooth type 4C (CMT4C) who developed seropositive myasthenia gravis. Neuromuscular junction alterations in CMT4C patients have not yet been reported. However, few patients have been reported to simultaneously have MG and CMT, but none with CMT4C. Our report suggests that additional research is required to confirm whether genetic neuropathies may predispose to MG.
