Abstract
• The peroxisomal disorders are a group of inherited metabolic diseases with serious clinical sequelae. The number of recognized peroxisomal disorders has increased substantially since 1973, when an absence of peroxisomes was observed in patients with the cerebrohepato-renal (Zellweger's) syndrome. More subtle peroxisomal dysfunction is now recognized, including that deriving from single peroxisomal enzymes. Peroxisomal disorders are relatively rare. However, these disorders assume importance because of our growing ability to relate clinical sequelae to specific enzymatic and biochemical deficits, because some of these disorders can now be identified prenatally and their recurrence can be prevented, and because therapies are rapidly evolving. We reviewed these disorders in light of increasing understanding of the biochemistry of the peroxisome. (AJDC1988;142:1297-1301)
