Abstract

Peroxisomes are single-membrane-bound organelles present in virtually all eukaryotic cells. They are involved in numerous metabolic processes, both catabolic and anabolic, including beta-oxidation of very long chain fatty acids, metabolism of hydrogen peroxide, plasmalogen biosynthesis and bile acid synthesis. In several genetic diseases, there is either isolated deficiency of a specific peroxisomal protein (single-protein deficiencies) or a defect in the formation of the organelle with loss of multiple peroxisomal functions (peroxisome biogenesis disorders). X-linked adrenoleukodystrophy is an example of the former, and the Zellweger spectrum of the latter. Peroxisome biogenesis disorders are inherited in an autosomal recessive manner and result from mutations in any of at least 12 PEX genes that encode peroxins. This article reviews the peroxisomal system, the clinical, biochemical and molecular aspects of peroxisomal disorders, and discusses recent scientific advances in the understanding of peroxisome biogenesis.
