    Abstract
    The COVID-19 pandemic has accounted for millions of infections and hundreds of thousand deaths worldwide in a short-time period. The patients demonstrate a great diversity in clinical and laboratory manifestations and disease severity. Nonetheless, little is known about the host genetic contribution to the observed interindividual phenotypic variability. Here, we report the first host genetic study in the Chinese population by deeply sequencing and analyzing 332 COVID-19 patients categorized by varying levels of severity from the Shenzhen Third People’s Hospital. Upon a total of 22.2 million genetic variants, we conducted both single-variant and gene-based association tests among five severity groups including asymptomatic, mild, moderate, severe, and critical ill patients after the correction of potential confounding factors. Pedigree analysis suggested a potential monogenic effect of loss of function variants in GOLGA3 and DPP7 for critically ill and asymptomatic disease demonstration.

    • 11月10日,深圳市第三人民医院等在Cell Discovery期刊发表题为“Initial whole-genome sequencing and analysis of the host genetic contribution to COVID-19 severity and susceptibility”的文章。研究人员初步分析了宿主基因对COVID-19严重程度和易感性的影响。 文章称,该研究通过对深圳第三人民医院不同严重程度分类的332例COVID-19患者进行深入测序和分析,首次在中国人群中进行宿主基因研究。该团队在校正了潜在的混杂因素之后,在总共2220万个遗传变异中,对五个严重程度组(包括无症状、轻度、中度、重度和重症患者)进行了单变量和基于基因的关联测试。谱系分析表明,对于危重病和无症状疾病,GOLGA3和DPP7中功能变异的丧失可能具有单基因效应。全基因组关联研究表明,与严重性相关的最重要基因位点位于参与IL-1信号通路的TMEM189–UBE2V1中。与轻度和普通人群相比,重症患者中影响TMPRSS2蛋白稳定性的p.Val197Met错义变体显示等位基因频率降低。该研究确定,HLA-A* 11:01,B* 51:01和C* 14:02等位基因明显诱发了患者的最坏结果。这项对中国患者的初步基因组研究为COVID-19患者群体的表型差异提供了遗传学方面的见解,并着重指出了可能有助于指导有针对性控制疫情的基因和变异。该文章还回顾了该研究的局限性和优点,以指导今后国际上阐明COVID-19和其他传染性和复杂疾病宿主-病原体相互作用的遗传结构的工作。 原文链接:https://www.nature.com/articles/s41421-020-00231-4

    • Dynamic data-driven meta-analysis for prioritisation of host genes implicated in COVID-19 Nicholas Parkinson, Natasha Rodgers, Max Head Fourman, Bo Wang, Marie Zechner, Maaike C. Swets, Jonathan E. Millar, Andy Law, Clark D. Russell, J. Kenneth Baillie & Sara Clohisey Scientific Reports volume 10, Article number: 22303 (2020) Abstract The increasing body of literature describing the role of host factors in COVID-19 pathogenesis demonstrates the need to combine diverse, multi-omic data to evaluate and substantiate the most robust evidence and inform development of therapies. Here we present a dynamic ranking of host genes implicated in human betacoronavirus infection (SARS-CoV-2, SARS-CoV, MERS-CoV, seasonal coronaviruses). We conducted an extensive systematic review of experiments identifying potential host factors. Gene lists from diverse sources were integrated using Meta-Analysis by Information Content (MAIC). This previously described algorithm uses data-driven gene list weightings to produce a comprehensive ranked list of implicated host genes. From 32 datasets, the top ranked gene was PPIA, encoding cyclophilin A, a druggable target using cyclosporine. Other highly-ranked genes included proposed prognostic factors (CXCL10, CD4, CD3E) and investigational therapeutic targets (IL1A) for COVID-19. Gene rankings also inform the interpretation of COVID-19 GWAS results, implicating FYCO1 over other nearby genes in a disease-associated locus on chromosome 3. Researchers can search and review the gene rankings and the contribution of different experimental methods to gene rank at https://baillielab.net/maic/covid19. As new data are published we will regularly update the list of genes as a resource to inform and prioritise future studies.
