The union of the two core two-stage SCOV2 molecular fingerprints identified from the previous experiments (23 genes for GSE151513 and 33 genes for GSE158930) consist of 38 genes being down-regulated in the EARLY SCOV2 infection stage, with 18 of them to be shared between the two fingerprints, namely: IFI27, IFI6 (IFI27-like/ISG12), IFIH1, IFIT1/2/3/5, IFITM1, ISG15, MX1/2, OAS1/2/3, RSAD2, STAT2, UBE2L6 and XAF1 (consult Supplement File DEGs.xlsx/′1_finger.Genes_UNION_COMMON′). The gene discussed is UBE2L6; the disease is infection.
