Description

The cholesteryl ester transfer protein (CETP) is a protein involved in the transfer of cholesteryl esters between lipoproteins. CETP is a crucial protein involved in the regulation of high density lipoprotein (HDL) levels and may affect susceptibility to age-related diseases, including atherosclerosis and Alzheimer's Disease (AD). A higher HDL/LDL ratio has been associated with healthier and longer-lived individuals. Accordingly, a polymorphism (I405V) in the CETP gene has been associated with longevity in some long-lived populations of healthy aging Ashkenazi Jews [2127] as well as in a cohort of Greek individuals [2128]. This however was not observed in a similar study with Italian centenaries [2129] and it appears that this polymorphism is not enough to universally determine longevity and other genes might play an important role.

CETP has been also associated with susceptibility to age-related diseases. For example, it was suggested that CETP behaves as a modifier gene of the AD risk associated with APOE [2130] and that the I405V polymorphism is associated with an increased risk of AD [2131]. CETP has been also identified as a susceptibility allele for advanced age-related macular degeneration [2133].
