Question

Quizplus · Accepted Answer

Studies have shown that a specific gene segment on chromosome 19, known as the APOE gene, is associated with an increased risk of developing late-onset Alzheimer's disease. The APOE gene provides instructions for making a protein called apolipoprotein E, which helps to transport cholesterol and other fats in the bloodstream. The presence of a certain variant, or allele, of the APOE gene, known as APOE ε4, is associated with a higher risk of developing Alzheimer's disease, and people with two copies of the APOE ε4 allele have an even higher risk.
