Five patients are described with a progressive sensory neuropathy in association with a spastic paraplegia and a mutilating lower limb acropathy. Disease onset was in childhood. Two pairs of siblings were both the offspring of normal consanguinous parents, suggesting autosomal recessive inheritance. The fifth case was sporadic; her parents were normal and non-consanguinous. Nerve biopsy in three patients showed an axonopathy with a loss of myelinated nerve fibres of all diameters and also of unmyelinated axons. In combination with the previous report by Cavanagh et al. (Brain 1979; 102: 7994), the present patients establish the existence of an autosomal recessive form of hereditary sensory neuropathy with spastic paraplegia. There have been previous descriptions of a dominantly inherited form.
