The<unk>  has been associated with two genetic mutations: a duplication of the PMP22 gene that carries the instructions for producing the peripheral myelin protein 22, a critical component of the myelin sheath; and a missense mutation in the MPZ gene which codes for myelin protein zero, a major structural protein of peripheral myelin. As PMP22 mutations are also associated with Charcot–Marie–Tooth disease type 1A and MPZ mutations are associated with Charcot–Marie–Tooth disease type 1B, it remains the subject of discussion whether the<unk>  is a separate entity or a specific phenotype of either disorder.
