Even if patients and carriers were to abstain from having children, CMT mutations occur de novo with some regularity and the disease would remain prevalent. Boerkoel and colleagues found that one third (6 of 16) of the point mutations detected in their series of 159 patients represent de novo events. [42] As examined by Hoogendijk and colleagues, of 10 patients with CMT1 and no family history, 9 of them had PMP22 duplications. [72]

Prevention should focus on avoiding conditions that can cause or worsen generalized or focal neuropathy, such as diabetes mellitus, vitamin deficiency, medication toxicity, and prolonged immobilization of limbs during surgery.
