To identify genes associated with SARS-CoV infection across strains, we used GSEA to compare icSARS gene panels to 18 gene signatures derived from samples of human lung cultures or mouse lung samples mock or SARS-CoV infected with one of six strains (Urbani, MA15, dORF6, BAT-SRBD, dNSP16, and ExoNI; Table 2). Here, BAAT is linked to severe acute respiratory syndrome.
