TMPRSS2 and viral infectious disease: The genes involved in viral infection reported in the literature are ACE2, TMPRSS2, ADAM17, NRP1, and NRP2. One literature review (Fulzele et al., 2020) identified 12 relevant microRNAs in the regulation of ACE2 (miR-18, miR-125b, miR-132, miR-143, miR-181, miR-200, miR-145, miR-155, miR-212, miR-421, miR-482-3p, and miR-4262).
