Description

Refsum disease is an autosomal recessive inborn error of lipid metabolism classically characterized by a tetrad of clinical abnormalities: retinitis pigmentosa, peripheral neuropathy, cerebellar ataxia, and elevated protein levels in the cerebrospinal fluid (CSF) without an increase in the number of cells. However, not all patients show all these features. All patients have accumulation of an unusual branched-chain fatty acid, phytanic acid, in blood and tissues. Other variable features include cardiac dysfunction, nerve deafness, ichthyosis, and multiple epiphyseal dysplasia (review by Skjeldal et al., 1987).Increased levels of phytanic acid can also be found in peroxisomal biogenesis disorders; see Zellweger syndrome (see {214100}) (Skjeldal et al., 1987).Infantile Refsum disease (see PBD1B, {601539}) is a distinct disorder with a different phenotype and genetic basis.A phenotype clinically indistinguishable from that of classic Refsum disease (PBD9B ), but with a different biochemical profile, can be caused by mutation in the gene encoding peroxin-7 (PEX7 ) on chromosome 6q.
