Evaluating the possible patterns of the relationship between eQTL frequencies and indicators of COVID-19 mortality (Figure 2), we found that countries with lower percentages of COVID-19 cases, CFR and deaths, such as Korea and Japan, tend to have lower frequencies of TMPRSS2, ACE2 and FURIN eQTL variants, as shown in the first row of Figure 2. The gene discussed is ACE2; the disease is COVID-19.
