APOE (Apolipoprotein E) is best known for lipid metabolism, but it also plays a role in blood sugar regulation. The ε4 allele has been associated with increased insulin resistance and higher risk of type 2 diabetes in some studies, while ε2 may be protective. Mechanisms include altered glucose uptake in the brain and modulation of insulin signaling. However, the effects are modest and heavily influenced by lifestyle, diet, and other genetic variants. A DNA test alone cannot measure current blood glucose levels; that requires a blood test. The evidence is human-moderate: associations exist but are not fully consistent. For personalized risk assessment, clinical evaluation and medical advice remain essential.
