In European ancestry, 111 genetic loci were identified as associated with atrial fibrillation (AF). We explored the reproducibility of those single nucleotide polymorphisms (SNPs) in a genome-wide association study (GWAS) meta-analysis of Far East Asian populations.
We performed a meta-analysis of the Korean AF network and Japanese AF data sets (9118 cases and 33 467 controls) by an inverse-variance fixed-effects model. We compared the results with 111 previously reported SNPs proven in Europeans after excluding 36 missing loci and a locus with a minor allelic frequency (MAF) < 0.01 in the European population.
Among remaining 74 loci, 29 loci were replicated at a P < .05, and 17 of those loci were newly found in the Far East Asian population: 3 loci with a P < 5×10 (METTL11B at 1q24, KCNN2 at 5q22 and LRMDA at 10q22), 4 loci at the threshold of the Bonferroni correction of P = 4.5 × 10 ~ 5×10 (KIF3C at 2p23, REEP3, NRBF2 at 10q21, SIRT1, MYPN at 10q21 and CFL2 at 14q13) and 10 SNPs with a P = .05 ~ 4.5 × 10 . Among 18 AF loci with a MAF< 0.01 in the Far East Asian populations, 2 loci (GATA4 at 8q23 and SGCG at 13q12) were replicated after a fine mapping. Twenty-seven AF loci, including a locus, which had a sufficient sample size to get a power of over 80% (with a type 1 error α = 4.5 × 10 ), were not replicated in the Far East Asian populations.
We newly replicated 19 AF-associated genetic loci in the European descent among the Far East Asian populations. It highlights the extensive sharing of AF genetic risks across Far East Asian populations.
在欧洲血统中,有 111 个遗传位点被确定与心房颤动(AF)相关。我们通过全基因组关联研究(GWAS)荟萃分析探索了这些单核苷酸多态性(SNP)在东亚人群中的可重复性。
我们通过逆方差固定效应模型对韩国 AF 网络和日本 AF 数据集(8118 例病例和 33467 例对照)进行荟萃分析。我们将结果与在欧洲人群中经排除 36 个缺失位点和一个等位基因频率(MAF)<0.01 的位点后证实的 111 个先前报告的 SNP 进行比较。
在其余的 74 个位点中,有 29 个在 P<0.05 时得到复制,其中 17 个在东亚人群中被新发现:3 个位点 P<5×10(METTL11B 在 1q24,KCNN2 在 5q22,LRMDA 在 10q22),4 个位点在 Bonferroni 校正的 P=4.5×105×10 边界(KIF3C 在 2p23,REEP3,NRBF2 在 10q21,SIRT1,MYPN 在 10q21 和 CFL2 在 14q13),还有 10 个 SNP 的 P=0.054.5×10。在东亚人群中 MAF<0.01 的 18 个 AF 位点中,有 2 个位点(GATA4 在 8q23 和 SGCG 在 13q12)在精细映射后得到复制。在东亚人群中,有 27 个 AF 位点,包括一个具有超过 80%的检测效能(α=4.5×10)的足够样本量的位点,未得到复制。
我们在东亚人群中欧洲血统中发现了 19 个新的与 AF 相关的遗传位点。这突出了 AF 遗传风险在东亚人群中的广泛共享。
