Hereditary induced peripheral neuropathies.

The hereditary neuropathies, representing up to 20 per cent of the total of peripheral neuropathies, present a considerable problem in neurology, rehabilitation medicine, and orthopedics. Patients have predominant foot abnormalities such as pes cavus and talipes equina varus. The largest section is the Charcot-Marie-Tooth syndrome or peroneal muscular atrophy, followed by the leucodystrophies and adrenal myloneuropathy. Information is burgeoning with the advent of molecular genetics, and we anticipate therapeutic options when gene products are discovered.
