We have previously reported an 8-year-old girl with lipoprotein glomerulopathy. Assessment of serum apolipoprotein E (apo E) in this patient showed a discrepancy between phenotype and genotype, suggesting that she may have a variant of apo E. The present report concerns our analysis of DNA sequences of the apo E gene in the patient: nine base pairs were found to be deleted from exon 4. This mutation would appear to encode a new apo E variant lacking three amino acids. This variant may be associated with the pathogenesis of lipoprotein glomerulopathy.

D001057 Apolipoproteins E A class of protein components which can be found in several lipoproteins including HIGH-DENSITY LIPOPROTEINS; VERY-LOW-DENSITY LIPOPROTEINS; and CHYLOMICRONS. Synthesized in most organs, Apo E is important in the global transport of lipids and cholesterol throughout the body. Apo E is also a ligand for LDL receptors (RECEPTORS, LDL) that mediates the binding, internalization, and catabolism of lipoprotein particles in cells. There are several allelic isoforms (such as E2, E3, and E4). Deficiency or defects in Apo E are causes of HYPERLIPOPROTEINEMIA TYPE III.
