我们汇总了来自32例欧洲血统GWAS（74，124例T2 D病例，824，006例对照）的全基因组基因分型数据，这些数据被输入到> 30，000个测序单倍型的高密度参考组中。对T27 M变异体（T21 M，次要等位基因频率[MAF]<5%）的分析，确定了243个全基因组显著位点（p<5x 10 -8; MAF 0.02%-50%;比值比[OR] 1.04-8.05），135个先前与T2 D易感性无关。条件分析揭示了160个额外的不同的关联信号（p<10-5）内确定的基因座。403个T2 D风险信号的组合集包括60个位点的56个低频（0.5%≤MAF<5%）和24个罕见（MAF<0.5%）索引SNP，其中14个估计等位基因OR>2。其中41个信号在BMI未调整和调整分析之间显示出效应量异质性。样本量的增加和插补的改进使得因果变异的定位比以前更精确：在51个信号中，精细定位后的前导变异占>80%的后验关联概率（PPA），其中18个信号的PPA超过99%。与针对T2 D关联而富集的胰岛调节注释的整合进一步降低了中值可信集大小（从42个变体到32个），并将PPA>80%的索引变体的数量扩展到73个。虽然大多数信号映射到调控序列，我们确定了18个基因作为人类验证的治疗靶点，通过编码变异是疾病的原因。全基因组芯片遗传性占T2 D风险的18%，并且从GWAS数据生成的多基因风险评分的2.5%极端中的个体在风险上相差>9倍。我们的观察结果强调了样本量和变异多样性的增加如何增强因果T2 D风险等位基因的发现和单变异分辨率，以及对机制见解和临床翻译的影响。
We aggregated genome-wide genotyping data from 32 European-descent GWAS (74,124 T2D cases, 824,006 controls) imputed to high-density reference panels of >30,000 sequenced haplotypes. Analysis of ˜27M variants (˜21M with minor allele frequency [MAF]<5%), identified 243 genome-wide significant loci (p<5x10-8; MAF 0.02%-50%; odds ratio [OR] 1.04-8.05), 135 not previously-implicated in T2D-predisposition. Conditional analyses revealed 160 additional distinct association signals (p<10-5) within the identified loci. The combined set of 403 T2D-risk signals includes 56 low-frequency (0.5%≤MAF<5%) and 24 rare (MAF<0.5%) index SNPs at 60 loci, including 14 with estimated allelic OR>2. Forty-one of the signals displayed effect-size heterogeneity between BMI-unadjusted and adjusted analyses. Increased sample size and improved imputation led to substantially more precise localisation of causal variants than previously attained: at 51 signals, the lead variant after fine-mapping accounted for >80% posterior probability of association (PPA) and at 18 of these, PPA exceeded 99%. Integration with islet regulatory annotations enriched for T2D association further reduced median credible set size (from 42 variants to 32) and extended the number of index variants with PPA>80% to 73. Although most signals mapped to regulatory sequence, we identified 18 genes as human validated therapeutic targets through coding variants that are causal for disease. Genome wide chip heritability accounted for 18% of T2D-risk, and individuals in the 2.5% extremes of a polygenic risk score generated from the GWAS data differed >9-fold in risk. Our observations highlight how increases in sample size and variant diversity deliver enhanced discovery and single-variant resolution of causal T2D-risk alleles, and the consequent impact on mechanistic insights and clinical translation.
