Rs5882

This SNP rs5882 in the CETP gene referred to as ILE405VAL and RSAI405V has been related to ageing and exceptional long life. A study in Ashkenazi Jews showed that individuals homozygotic for the G allele have significantly longer lifespans.

New research also indicates that G homozygotes have an average of 70% less risk of dementia and Alzheimer's disease. The study also found that heterozygotes have a lower risk of dementia and Alzheimer's disease but more study is needed to determine the risk reduction for heterozygotes.
