On the other hand, TAS2R38 DNAm in post-COVID-19 participants of the second group, i.e. at the time when there was not any active disease, the ∆Ct mean values were associated with the TAS2R38 genotype of participants (H[2,32] = 8.514, P = 0.0142, Kruskal-Wallis test) (Fig. 4B). This evidence concerns the gene TAS2R38 and COVID-19.
