Resumen

Objective-The function of high-density lipoproteins (HDLs) may better reflect their atheroprotective role, compared with HDL-cholesterol levels. The association between DNA methylation and HDL function has not yet been established. Approach and Results-We designed an epigenome-wide association study including 645 individuals from the REGICOR study (Registre Gironi del Cor). We determined DNA methylation from peripheral blood cells using the HumanMethylation450 array. We analyzed HDL functionality by determining HDL cholesterol efflux capacity and HDL inflammatory index. We discovered 3 methylation sites located in HOXA3, PEX5, and PER3 related to cholesterol efflux capacity and 1 located in GABRR1 related to HDL inflammatory index. Using a candidate gene approach, we also found 2 methylation sites located in CMIP related to cholesterol efflux capacity. Conclusions-We identified 6 potential loci associated with HDL functionality in HOXA3, PEX5, PER3, CMIP, and GABRR1. Additional studies are warranted to validate these findings in other populations.
