title: Organelle disease: peroxisomal disorders.
abstract: Peroxisomes are virtually ubiquitous organelles involved in numerous catabolic and anabolic pathways. Interest in peroxisomes stems from an expanding group of genetic diseases in which there is either deficiency of a specific peroxisomal function (single protein defects) or failure to assemble the organelle resulting in defects of multiple peroxisome functions (peroxisome biogenesis disorders). The paradigm for the former is X-linked adrenoleukodystrophy caused by mutations in the adrenoleukodystrophy gene and, for the latter, Zellweger syndrome caused by mutations in peroxin genes.
  
  
  CONCLUSIONS
  The identification and functional characterisation of the peroxisomal disease genes is proceeding at rapid pace helped immeasurably by work in various yeast model systems. The ultimate goal is to elucidate how the encoded proteins produce normal appearing and functioning peroxisomes. The achievement of this goal will lead to a better understanding of peroxisomal disorders, their pathogenesis and treatment.
