title: Association of selected ABC gene family single nucleotide polymorphisms with postprandial lipoproteins: results from the population-based Hortega study.
abstract: The aim of the study was to determine the influence of twenty single nucleotide polymorphisms (SNPs) of the ABCA1, ABCG1, ABCG5 and ABCG8 genes on the plasmatic concentrations of total cholesterol (TC), HDL and LDL cholesterol (HDLc, LDLc) in the postprandial state with a representative Spanish Caucasian population (1473 individuals, 50.0% women, ages ranging 21-85 years). In men, subjects with the AA genotype of the ABCA1 rs2230806 (R219K) polymorphism were associated with increased plasma LDLc levels, while the ABCA1 haplotype, which included the rs2230806 A allele, was associated with higher TC and LDLc plasma concentrations. In women, significant relationships were found between rs1893590 polymorphisms (ABCG1 gene) and HDLc plasma concentrations (subjects with the AA genotype had lower HDLc levels). For the ABCG8 gene, the rs4148211 polymorphism was associated with higher plasma TC and LDLc concentrations in the total population. Moreover, an ABCG5-G8 haplotype, which included the rs6544718 T allele, was associated with higher HDLc plasma concentrations in women. In conclusion, different SNPs of the ABCA1, ABCG1 and ABCG5-ABCG8 genes were associated, some under gender-specific analysis, with variations in the plasma lipid levels under postprandial conditions in a representative Spanish population.
