Apolipoprotein E polymorphism in health and disease

Utermann, Gerd·1987·American Heart Journal

Abstract

Genetic polymorphism of apolipoprotein (apo) E is controlled by three common (epsilon 2, epsilon 2, epsilon 4) and several rare alleles (e.g., epsilon 1, epsilon 4*, epsilon 4v) at the apo E structural gene locus and may be demonstrated by isoelectric focusing of delipidated sera followed by immunoblotting. Apo E allele frequencies vary significantly between different ethnic groups. The common apo E isoforms E2 (arg158----cys) and E4 (cys112----arg) differ functionally from the parent E3 isoform, explaining their effects on the normal variance of plasma lipoprotein concentrations and their association with hyperlipidemic conditions. In all studied populations the receptor-binding defective apo E2 (arg158----cys) is associated with low cholesterol and apo B in heterozygotes and results in primary dysbetalipoproteinemia or type III hyperlipoproteinemia in homozygotes. Conversely, the epsilon 4 allele is associated with high cholesterol in Finns and Germans but less or not significantly so in Japanese or Singapore populations. In addition to their effects on the normal variance of lipoprotein concentrations, the alleles epsilon 2 and epsilon 4 are associated with hypertriglyceridemia and hypercholesterolemia, respectively. A working hypothesis explaining these observations is presented.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
