Peroxisomal Disorders


Zellweger’s syndrome is an X-linked autosomal recessive disorder of peroxisomal biogenesis with an absence of the peroxisome. There is a wide range of characteristic dysmorphic features and cerebrohepatorenal involvement. Laboratory studies characteristic of Zellweger’s syndrome include (1) elevated levels of pipecolic acid in plasma, cerebrospinal fluid (CSF) and urine; (2) elevated levels of saturated (C26) and monosaturated (C26 : 1) VLCFA in plasma, body fluids, and tissues with an elevated C26 : 0/C22 : 0 ratio; (3) decreased (<10% of normal) tissue level of phosphatidyl ethanolamine plasmalogen, a phospholipid constituent of myelin and platelet-activating factor; and (4) deficient activity of dehydroxyacetone phosphate acyltransferase, the key enzyme in the pathway for plasmalogen synthesis (located in the peroxisomal membrane).
