| refsum disease | A chronic progressive peripheral neuropathy which is probably inherited in an autosomal recessive manner. Some of the manifestations of this disorder are atypical retinitis pigmentosa, cerebellar ataxia, and increased cerebrospinal protein levels. Excessive phytanic acid storage has been found in most cases. Onset of symptoms usually occurs in early childhood. Infantile refsum disease (see peroxisomal disorders) differs in that it also includes mental retardation, dysmorphic features, peroxisomal deficiency, and very early onset. (12 Dec 1998) |

| refsum's disease | A genetic disorder of the fatty acid phytanic acid which accumulates and causes a number of progressive problems including polyneuritis (inflammation of numerous nerves), diminishing vision (due to retinitis pigmentosa), and wobbliness (ataxia) caused by damage to the cerebellar portion of the brain (cerebellar ataxia).

| Refsum's d. |
an autosomal recessive disorder of lipid metabolism in which deficiency of phytanic acid α-hydroxylase results in accumulation of phytanic acid; it is manifest chiefly by chronic polyneuritis, retinitis pigmentosa, cerebellar ataxia, and persistent elevation of protein in cerebrospinal fluid; there may also be ichthyosis, nerve deafness, and electrocardiographic abnormalities. Called also phytanic acid storage d., and heredopathia atactica polyneuritiformis.
