Hereditary, non HINT1 related, axonal neuropathy with neuromyotonia.

To date, neuromyotonia in the context of an inherited axonal neuropathy has been linked to autosomal recessive mutations in the histidine triad nucleotide binding protein 1 (HINT1) gene. In this study we describe two unrelated male patients with late-onset, predominantly motor, axonal neuropathy with neuromyotonia, who carried an autosomal dominant c.103G > A mutation in the myelin protein zero (MPZ) gene (NM_000530.
