2017年4月1日,基于华大基因的BGISEQ-500测序平台第一篇关于人全基因组测序的论文发表了。主要结论是:BGISEQ-500二代高通量测序平台的比对与变异检测方面与Illumina的HiSeq 2500表现出较高的一致性。
论文题目:A reference human genome dataset of the BGISEQ-500 sequencer
发表期刊:Giga Science
发表时间:2017年4月1日
影响因子:7.463
合作单位:华大基因、国家食品药品监督管理总局(NIFDC)和国家食品药品监督管理局湖北医疗器械质量监督检验中心
比较平台:BGISEQ-500 VSHiSeq 2500
样本选择:选择的样品是被广泛使用的“瓶中基因组”联盟发布的人类细胞系HG001(NA12878)。
研究方法:本论文发布了BGISEQ-500 PE100、PE50的人类全基因组测序数据,研究人员选取相同数据量的HiSeq 2500 PE150的数据集,采用相同的分析、统计方法,对两个平台的数据质量、比对结果、变异检测等进行了比较。
原文摘要:
Background: BGISEQ-500 is a new desktop sequencer developed by BGI. Using DNA nanoball and combinational probe anchor synthesis developed from Complete Genomics™ sequencing technologies, it generates short reads at a large scale. Findings: Here, we present the first human whole-genome sequencing dataset of BGISEQ-500. The dataset was generated by sequencing the widely used cell line HG001 (NA12878) in two sequencing runs of paired-end 50 bp (PE50) and two sequencing runs of paired-end 100 bp (PE100). We also include examples of the raw images from the sequencer for reference. Finally, we identified variations using this dataset, estimated the accuracy of the variations, and compared to that of the variations identified from similar amounts of publicly available HiSeq2500 data. Conclusions: We found similar single nucleotide polymorphism (SNP) detection accuracy for the BGISEQ-500 PE100 data (false positive rate [FPR] = 0.00020%, sensitivity = 96.20%) compared to the PE150 HiSeq2500 data (FPR = 0.00017%, sensitivity = 96.60%) better SNP detection accuracy than the PE50 data (FPR = 0.0006%, sensitivity = 94.15%). But for insertions and deletions (indels), we found lower accuracy for BGISEQ-500 data (FPR = 0.00069% and 0.00067% for PE100 and PE50 respectively, sensitivity = 88.52% and 70.93%) than the HiSeq2500 data (FPR = 0.00032%, sensitivity = 96.28%). Our dataset can serve as the reference dataset, providing basic information not just for future development, but also for all research and applications based on the new sequencing platform.
华大基因毕竟也是SCI发表大户,很懂得通过国际同行评议来验证产品质量。这已经比很多会营销的商家靠谱多了,不是吗?
当然会发现还有不少问题,比如原文提到的在基因插入和删除检测上华大测序仪的准确度更低。期待国产测序仪不断改进和创新,追赶Illumina这样的国际巨头。
