HLA是病毒抗原呈递途径的关键组分。我们调查了3,235例确诊的SARS-CoV-2感染者的SARS-CoV-2疾病严重程度与HLA分型之间的关系。我们发现只有DPB 1基因座与个体是否出现任何COVID-19症状的二元结果相关。预测结合HLA等位基因的肽的数量与疾病的严重程度没有显着的关系时,分层的祖先或年龄的个人,并在汇总分析。总体而言,在人群水平上,我们发现HLA类型对COVID-19疾病严重程度的预测性明显低于某些人口统计学因素和临床合并症。
HLA is a critical component of the viral antigen presentation pathway. We investigated the relationship between severity of SARS-CoV-2 disease and HLA type in 3,235 individuals with confirmed SARS-CoV-2 infection. We found only the DPB1 locus to be associated with the binary outcome of whether an individual developed any COVID-19 symptoms. The number of peptides predicted to bind to an HLA allele had no significant relationship with disease severity both when stratifying individuals by ancestry or age and in a pooled analysis. Overall, at the population level, we found HLA type is significantly less predictive of COVID-19 disease severity than certain demographic factors and clinical comorbidities.
