The APOE Puzzle: Variants, Risks, and Heart Health Solutions

Apolipoprotein E (APOE) is a protein that plays a pivotal role in lipid metabolism, shuttling cholesterol and other fats through the bloodstream as part of lipoproteins. The APOE gene, located on chromosome 19, comes in three main variants—ε2, ε3, and ε4—each with distinct effects on cardiovascular health and other conditions like Alzheimer’s disease. These variants influence how efficiently your body clears cholesterol, impacting your risk of heart disease, stroke, and more. In this blog, we’ll explore the science behind APOE variants, their association with heart disease, and practical ways to manage risks if you carry higher-risk alleles.
