Result: In particular, there were also some mutation combinations, such as P504L/Y541C in nsp13 and R203K/G204R in N (Table S1).
Genetic conservation of SARS-CoV-2 RNA replication complex in globally circulating isolates and recently emerged variants from humans and minks suggests minimal pre-existing resistance to remdesivir.
Introduction: Additionally, three concurrent missense mutations 17747C>T-(P504L), 17858A>G-(Y541C), and 28144T>C-(L84S) tend to fade out, while the other eight concurrent mutations may enhance the infectivity of SARS-CoV-2.
Result: The other three mutations, 17747C>T-(P504L), 17858A>G-(Y541C), and 28144T>C-(L84S), occur mostly together and have similar numbers of frequencies.
Result: Three of the top 11 missense mutations, i.e., 17858A>G-(

Abstract: Subclade 1C with the amino acid changes at nsp13 P504L and ORF8 L84S was becoming the second most frequent sub-haplogroup in the world (19.91%) and America (26.29%).
Result: Sub-clade 1C with the amino acid changes at nsp13 P504L and ORF8 L84S was the largest sub-haplogroup in clade 1 among all genome sequences from g

Result: Some notable substitutions, co-occurring mutations, deletions and insertions which occur with a low to moderate recurrence and may have a significant influence on the viral pathogenic mechanism are: co-deletion (dependent) of K141, S142 and F143, co-deletion (dependent) of G82 and H83, D75E, co-occurring (dependent) S135N, Y136 deletion and M85 deletion in Nsp1, D268 deletion, G212D, co-occurring (dependent) I559V and P585S, F10L, V198I, P91S, T166I, H237R, T371I, S211F and G339S in Nsp2, PMID: 34735950
