SMG1 and COVID-19: We note that this set of genes (KRT8, TESC, TTC33, LOC100422212, SEC14L1, ALCAM, PARP9, and FNDC3B) does not overlap with the set of genes (ABCB6, KIAA1614, MND1, SMG1, RIPK3, CDC6, ZNF282, and CEP72) identified at the genomic level as a set of COVID-19 biomarkers with optimum performance, based on whole blood samples [8,9,10].
