A relatively mild peroxisome biogenesis disorder. Affected individuals manifest lower limb spasticity and ataxia resulting in wheelchair dependence. Other features include optic atrophy, cataracts, dysarthria, dysphagia, constipation, and a peripheral demyelinating motor and sensory neuropathy. Cognition is relatively preserved. Biochemical abnormalities are mild and include increased very-long-chain fatty acids (VLCFA), increased bile acid intermediates, and increased branched chain fatty acids. Phytanic acid alpha-oxidation, pristanic acid beta-oxidation, and red cell plasmalogen are normal.
