The data showed that out of 114 asymptomatic donors, 84 were positive for serum AC (73.7%), whereas only 2 out of 23 COVID-19 patients were positive for AC protein in their serum samples (8.6%), which were similar to the AC positive donors who were negative for the SARS-CoV-2 antibody (6 out of 23, 26%) (Fig. 4F). The gene discussed is ASAH1; the disease is COVID-19.
