No impact of SARS-CoV-2 infection on mRNA expression levels of key genes involved in miRNA biogenesis was observed, in contrast to the study by Mousavi et al., who found that mRNA levels of AGO2, DICER1, and DROSHA, but not DGCR8, differed between COVID-19 patients and controls [65]. This evidence concerns the gene AGO2 and COVID-19.
