title: Analysis of very long-chain fatty acids and plasmalogen in the erythrocyte membrane: a simple method for the detection of peroxisomal disorders and discrimination between adrenoleukodystrophy and Zellweger syndrome.
abstract: We analyzed the sphingomyelin very long-chain fatty acids (VLCFAs) and phosphatidylethanolamine (PE) plasmalogen contents of the erythrocyte membrane in patients suffering from peroxisomal disorders. In a patient with Zellweger syndrome, both a decrease in the PE plasmalogen content and an increase in the sphingomyelin VLCFAs content of the erythrocyte membrane were noted. In patients with adrenoleukodystrophy, however, there was no decrease in PE plasmalogen, although the sphingomyelin VLCFAs content of the membrane was significantly increased in comparison with control values. Analyses of both sphingomyelin VLCFAs and PE plasmalogen were carried out simultaneously, using both the same process and the same sample.
