The peroxisomal disorders are subdivided into two major categories: those in which the organelle is not formed normally (disorders of peroxisome biogenesis), and those that are associated with defects of single peroxisomal proteins. The Zellweger cerebrohepatorenal syndrome is the prototype of the peroxisome biogenesis disorders. It has been shown to be due to defective import of proteins into the organelle. Ten distinct molecular defects can lead to the failure of import.

D018901	Peroxisomal Disorders	A heterogeneous group of inherited metabolic disorders marked by absent or dysfunctional PEROXISOMES. Peroxisomal enzymatic abnormalities may be single or multiple. Biosynthetic peroxisomal pathways are compromised, including the ability to synthesize ether lipids and to oxidize long-chain fatty acid precursors. Diseases in this category include ZELLWEGER SYNDROME; INFANTILE REFSUM DISEASE; rhizomelic chondrodysplasia (CHONDRODYSPLASIA PUNCTATA, RHIZOMELIC); hyperpipecolic acidemia; neonatal adrenoleukodystrophy; and ADRENOLEUKODYSTROPHY (X-linked). Neurologic dysfunction is a prominent feature of most peroxisomal disorders.
