Peroxisome Biogenesis Disorders: Biological, Clinical and Pathophysiological Perspectives
Braverman, Nancy E.; D'Agostino, Maria Daniela; MacLean, Gillian E.
Developmental Disabilities Research Reviews, v17 n3 p187-196 Jun 2013
The peroxisome biogenesis disorders (PBD) are a heterogeneous group of autosomal recessive disorders in which peroxisome assembly is impaired, leading to multiple peroxisome enzyme deficiencies, complex developmental sequelae and progressive disabilities. Mammalian peroxisome assembly involves the protein products of 16 "PEX" genes; defects in 14 of these have been shown to cause PBD. Three broad phenotypic groups are described on a spectrum of severity: Zellweger syndrome is the most severe, neonatal adrenoleukodystrophy is intermediate and infantile Refsum disease is less severe. Another group is Rhizomelic chondrodysplasia punctata spectrum. Recently, atypical phenotypes have been described, indicating that the full spectrum of these disorders remains to be identified. For most patients, there is a correlation between clinical severity and effect of the mutation on PEX protein function. Diagnosis relies on biochemical measurements of peroxisome functions and "PEX" gene sequencing. There are no targeted therapies, although management protocols have been suggested and research endeavors continue. In this review we will discuss peroxisome biology and PBD, and research contributions to pathophysiology and treatment. (Contains 3 tables and 2 figures.)
