Venous thromboembolism occurs in up to one-third of patients with COVID-19. Venous thromboembolism and COVID-19 may share a common genetic architecture, which has not been clarified. To fill this gap, we leverage summary-level genetic data from the latest COVID-19 host genetics consortium and UK Biobank and examine the shared genetic etiology and causal relationship between COVID-19 and venous thromboembolism. The cross-trait and co-localization analyses identify 2, 3, and 4 shared loci between venous thromboembolism and severe COVID-19, COVID-19 hospitalization, SARS-CoV-2 infection respectively, which are mapped to ABO, ADAMTS13, FUT2 genes involved in coagulation functions. Enrichment analysis supports shared biological processes between COVID-19 and venous thromboembolism related to coagulation and immunity. Bi-directional Mendelian randomization suggests that venous thromboembolism was associated with higher risk of three COVID-19 traits, and SARS-CoV-2 infection was associated with a higher risk of venous thromboembolism. Our study provides timely evidence for the genetic etiology between COVID-19 and venous thromboembolism (VTE). Our findings contribute to the understanding of COVID-19 and VTE etiology and provide insights into the prevention and comorbidity management of COVID-19.
静脉血栓栓塞症(VTE)在高达三分之一的 COVID-19 患者中发生。静脉血栓栓塞症和 COVID-19 可能具有共同的遗传结构,但尚未阐明。为了填补这一空白,我们利用来自最新 COVID-19 宿主遗传学联盟和英国生物银行的汇总水平遗传数据,研究 COVID-19 和 VTE 之间的共同遗传病因学和因果关系。跨特征和共定位分析在静脉血栓栓塞症和严重 COVID-19、COVID-19 住院、SARS-CoV-2 感染之间分别识别出 2、3 和 4 个共享位点,这些位点映射到涉及凝血功能的 ABO、ADAMTS13、FUT2 基因。富集分析支持 COVID-19 和静脉血栓栓塞症之间与凝血和免疫相关的共同生物学过程。双向 Mendelian 随机化表明,静脉血栓栓塞症与 COVID-19 的三种特征(严重程度、住院治疗、感染 SARS-CoV-2)的风险增加相关,而 SARS-CoV-2 感染与静脉血栓栓塞症的风险增加相关。我们的研究为 COVID-19 和 VTE 之间的遗传病因提供了及时的证据。我们的研究结果有助于理解 COVID-19 和 VTE 的病因,并为 COVID-19 的预防和合并症管理提供了新的见解。
