APOE Genotype
APOE genotype identifies the variants of the apolipoprotein E gene (E2, E3, E4) that influence lipid metabolism and brain function. Carrying one APOE4 allele raises Alzheimer disease risk about threefold, and two alleles raise it substantially more. APOE4 also affects LDL cholesterol and cardiovascular risk, and genotype is generally tested once because it does not change.
