Abstract:
Zellweger syndrome (cerebrohepatorenal syndrome) is very rare and is the most severe form of peroxisomal biogenesis disorders. These can be caused by mutations in any of the currently known Peroxin genes and typically present in the neonatal period with multiorgan involvement. Patients usually do not survive beyond 1 year of age. This article reports a case of Zellweger syndrome in a male Native American infant confirmed by clinical findings, imaging studies, and biochemical analysis. Genetic studies show a novel mutation (c.3030G>T, p. Glutamine1010Histidine) altering the last nucleotide of exon 19 in the Peroxin1 (PEX1) gene.

Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...
