Abstract

Context: We have previously shown that rare mutations in the apolipoprotein B gene (APOB) may result in not only severe hypercholesterolemia and ischemic heart disease but also hypocholesterolemia. Despite this, common single-nucleotide polymorphisms (SNPs) in APOB have not convincingly been demonstrated to affect low-density lipoprotein (LDL) cholesterol levels. Objective: We tested the hypothesis that nonsynonymous SNPs in three important functional domains of APOB and APOB tag SNPs predict levels of LDL cholesterol and apolipoprotein B and risk of ischemic heart disease. Design: This was a prospective study with 25 yr 100% follow up, The Copenhagen City Heart Study. Setting: The study was conducted in the Danish general population. Participants: Participants included 9185 women and men aged 20-80+ yr. Main Outcome Measures: Levels of LDL cholesterol and apolipoprotein B and risk of ischemic heart disease and myocardial infarction were measured. The hypothesis was formulated before genotyping. Results: We genotyped 9185 individuals for APOB T71I (minor allele frequency: 0.33), Ivs4 + 171c > a (0.14), A591V (0.47), Ivs18 + 379a > c (0.30), Ivs18 + 1708g > t (0.45), T2488Tc > t (0.48), P2712L (0.21), R3611Q (0.09), E4154K (0.17), and N4311S (0.21). SNPs were associated with increases (T71I, Ivs181708g > t, T2488Tc > t, R3611) or decreases (Ivs4 + 171c > a, A591V, Ivs18 + 379a > c, P2712L, E4154, N4311S) in LDL cholesterol from -4.7 to +8.2% (-0.28 to 0.30 mmol/liter; P <= 0.002), and corresponding effects on cholesterol and apolipoprotein B levels. However, as predicted from the magnitude of the observed LDL cholesterol effects, none of these SNPs predicted risk of ischemic heart disease prospectively in the general population, in a case-control study, or as haplotypes. Conclusions: Multiple common and rare alleles in APOB contribute to plasma levels of LDL cholesterol in the general population, although the effects of common alleles and haplotypes are modest
