This paper was the first study to report an association between XAF1 and SARS-CoV infections for any strain, to the best of our knowledge, though a recent report examining differential gene expression associated with SARS-CoV-2 infection identified increased expression of CXCL10, OAS3, IFIT3, and XAF1 in human epithelial lung cells and lung samples from Cynomolgus maca (cynomolgus monkey) and mice (35). This evidence concerns the gene OAS3 and severe acute respiratory syndrome.
