血液低密度脂蛋白(LDL)胆固醇、高密度脂蛋白(HDL)胆固醇和甘油三酯水平是心血管疾病的危险因素。为了剖析这些性状的多基因基础,我们在19840个个体中进行了全基因组关联筛选,并在20623个个体中进行了复制。我们确定了30个与脂蛋白浓度相关的不同位点(每个位点的P < 5 × 10-8),其中11个位点首次达到全基因组意义。这11个新定义的基因座包括ABCG8、MAFB、HNF1A和TIMD4附近与LDL胆固醇相关的常见变异;HDL胆固醇位于ANGPTL4、FADS1-FADS2-FADS3、HNF4A、LCAT、PLTP和TTC39B附近;甘油三酯位于AMAC1L2、FADS1-FADS2-FADS3和PLTP附近。高LDL胆固醇、低HDL胆固醇和高甘油三酯超过临床切点的个体比例根据等位基因剂量评分而变化(每种趋势P < 10-15)。这些结果表明,多种常见变异的累积效应有助于多基因血脂异常。
Blood low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol and triglyceride levels are risk factors for cardiovascular disease. To dissect the polygenic basis of these traits, we conducted genome-wide association screens in 19,840 individuals and replication in up to 20,623 individuals. We identified 30 distinct loci associated with lipoprotein concentrations (each with P < 5 × 10-8), including 11 loci that reached genome-wide significance for the first time. The 11 newly defined loci include common variants associated with LDL cholesterol near ABCG8, MAFB, HNF1A and TIMD4; with HDL cholesterol near ANGPTL4, FADS1-FADS2-FADS3, HNF4A, LCAT, PLTP and TTC39B; and with triglycerides near AMAC1L2, FADS1-FADS2-FADS3 and PLTP. The proportion of individuals exceeding clinical cut points for high LDL cholesterol, low HDL cholesterol and high triglycerides varied according to an allelic dosage score (P < 10-15 for each trend). These results suggest that the cumulative effect of multiple common variants contributes to polygenic dyslipidemia.
