【2020 Nature磕洪;Identification of type 2 diabetes loci in 433,540 East Asian individuals】Here, to examine T2D risk in East Asian individuals, we carried out a meta-analysis of GWAS data from 77,418 individuals with T2D and 356,122 healthy control individuals (effective sample size, Neff = 211,793).?we identified 301 distinct association signals at 183 loci.?we identified 61 loci that are newly implicated in predisposition to T2D.?We defined ‘lead’ variants as the strongest T2D-associated variants with P < 5 × 10?8 and defined the region ±500 kb from the lead variant as a locus.?我們將“先導(dǎo)”變體定義為 P < 5 × 10?8 的最強 T2D 相關(guān)變體吭练,并將先導(dǎo)變體 ±500 kb 的區(qū)域定義為基因座。A locus was considered ‘novel’ if the lead variant was located at least 500 kb from previously reported T2D-associated variants in any ancestry.?如果先導(dǎo)變異位于任何祖先中與之前報道的 T2D 相關(guān)變異至少 500 kb 的位置析显,則該位點被認為是“新穎的”鲫咽。we identified lead variants associated with T2D at 183 loci, of which 51 were novel.?我們在 183 個位點鑒定了與 T2D 相關(guān)的先導(dǎo)變異,其中 51 個是新的谷异。Lead variants at all novel loci were common (minor allele frequency (MAF) ≥ 5%)分尸。所有新位點的先導(dǎo)變異都很常見(次要等位基因頻率 (MAF) ≥ 5%)。Using genome-wide complex trait analysis (GCTA), we identified 301 distinct association signals that met a locus-wide significance threshold of P < 1 × 10?5, 228 of which were genome-wide significant (P < 5 × 10?8). 使用全基因組復(fù)雜性狀分析 (GCTA)歹嘹,我們確定了 301 個不同的關(guān)聯(lián)信號箩绍,這些信號滿足 P < 1 × 10?5 的全基因座顯著性閾值,其中 228 個具有全基因組顯著性 (P < 5 × 10?8)尺上。Overall, we observed 2–4 signals at 46 loci and 5 or more signals at 12 loci.?總體而言材蛛,我們在 46 個位點觀察到 2-4 個信號圆到,在 12 個位點觀察到 5 個或更多信號。
