| A rare subtype of axonal hereditary motor and sensory neuropathy with characteristics of distal muscle weakness and atrophy (principally of peroneal muscles) associated with distal sensory loss (tactile, vibration), pes cavus present since infancy or childhood and axonal swelling with neurofilament accumulation on nerve biopsy. Other features may include hand muscle involvement, hypo/areflexia, gait disturbances, muscle cramps, toe abnormalities and mild cardiomyopathy. There is evidence this disease is caused by heterozygous mutation in the DCAF8 gene on chromosome 1q23. |
