Apolipoprotein E (ApoE) is a polymorphic glycoprotein which plays a role in the transport and metabolism of triglyceride-cholesterol and is known to be synthesized in the liver, brain and other organs. It is encoded by the APOE gene, which has three different alleles (ε2, ε3, ε4) that encode for three different ApoE protein isoforms (ApoE2, ApoE3, and ApoE4). A combination of these isoforms results in 6 phenotypes (3 homozygous types (E2/E2; E3/E3; E4/E4) and 3 heterozygous types (E2/E3; E3/E4; E2/E4)).1,2
When used in conjunction with the Lumipulse G ApoE4 assay to determine the ApoE4/Pan-ApoE ratio, this ratio can be used to determine the ApoE proteotype status related to ApoE4, meaning absence (null) or presence of ApoE4 only (homozygous) or the combination with ApoE2 or E3 (heterozygous).
The assay reflects the ApoE4 protein expression level rather than the genotype, as evidenced by the observation that liver-transplanted patients have the phenotype of the donor.3
