Apolipoprotein E (ApoE) is a protein involved in cholesterol transport and metabolism. The three common variants — E2, E3, and E4 — influence how your body processes dietary fat and cholesterol. The E4 variant is associated with higher LDL cholesterol, increased cardiovascular risk, and a stronger response to dietary saturated fat. The E2 variant is associated with lower LDL but can increase triglycerides. Knowing your ApoE genotype helps personalize dietary and lifestyle recommendations for heart health and can inform statin therapy decisions.
