AN adult onset novel disorder of peroxisomal function is described, characterised by retinitis pigmentosa resulting in progressive visual failure, learning difficulties, a peripheral neuropathy, and hypogonadism. The defect results in accumulation of pristanic acid, and the bile acid intermediates, dihydroxycholestanoic and trihydroxycholestanoic acid, and is due to a deficiency of alpha-methylacyl-CoA racemase, making this the first fully characterised description of this defect. Screening of patients with retinitis pigmentosa should be extended to include pristanic acid and/or bile acid intermediate concentrations, as dietary measures offer a potential treatment for the disorder.
