A highly accurate test for the measurement of Apo E
Apo E deficiency causes high serum cholesterol and triglyceride levels and leads to premature atherosclerosis. Apo E has also been shown to affect the formation of atherosclerotic lesions by inhibition of platelet aggregation.
An APO E test is carried out to:
- help confirm a diagnosis of type III hyperlipoproteinaemia
- evaluate a possible genetic cause of atherosclerosis
- help confirm a diagnosis of late onset Alzheimer’s Disease
Apo E belongs to a group of proteins that bind reversibly with lipoprotein and play an important role in lipid metabolism. These proteins also help to maintain the structural integrity of lipoproteins, serve as ligands for lipoprotein receptors and regulate the activity of enzymes involved in lipid metabolism. Apo E directs the lipoprotein to the correct site of metabolism. Apo E is a ligand for LDL and mediates the receptor binding of Apo E lipoproteins to the LDL receptor protein.
Defects in Apo E are a cause of hyperlipoproteinemia type III. Apo E exists in three major isoforms: E2, E3 and E4, which differ from one another by a single amino acid substitution. E3 is the most common isoform and is present in 77% of the Caucasian population. Individuals heterozygous for E4 are associated with a higher risk for late onset Alzheimer’s disease.
