The ΔCt and ΔΔCt levels for TYK2 were notably higher in the COVID-19 patients than in the controls [9.02 vs. 7.79, p-value = 0.028; 1.23 vs. 2.8571 × 10−10, p-value = 0.028, respectively, (Table 2)], suggesting decreased gene expression in the COVID-19 patients. This evidence concerns the gene TYK2 and COVID-19.
