Results showed a differential expression of three out of six genes analyzed when comparing COVID-19-positive vs. -negative patients: IFNGR1 expression was decreased (p = 0.028) (Figure 2B(ii)), while JAK2 and STAT1 expressions were increased (p ≤ 0.001 for both genes) (Figure 2B(v,vi), respectively). This evidence concerns the gene JAK2 and COVID-19.
