From 45828 SARS-CoV-2 genome sequences available in the GISAID database as of June 13, 2020, 103 strains of SARS-CoV-2 1 https://www.ncbi.nlm.nih.gov/Class/Structure/aa/aa_explorer.cgi carried various DNA mutations including 25 unique ones that may affect the furin cleavage site located at the amino acid residual positions 680-689 (S1/S2 region) (Coutard et al., 2020; Wang et al., 2020; Zhang et al., 2020) of the SARS-CoV-2 spike protein (Figure 1 , Table 1, and Supplementary Table 1) . We uncovered 103 SARS-CoV-2 strains from multiple geographic regions, 81 of which carried 25 unique mutations that may affect the furin cleavage site in the spike glycoprotein. ./cache/cord-289134-ne3tjt5g.txt ./txt/cord-289134-ne3tjt5g.txt
