Notes

From SNPedia

The initial report noted on the SNP page found that those with GG and epsilon 4 genotype had their increased risk of Alzheimer's annulled. It not clear whether this applies only to single epsilon 4 carriers. Also, further research will be necessary to confirm this in larger samples.
