Four of ten endemic strains of SARS-CoV-2 developed 9 to 12mer nucleotide insertions. One strain (A607) developed two different insertions sequentially. The nucleotide sequences, positions and translations into amino acid codons are shown here.
The insertion labelled with a “∗” is a temporary insertion, later replaced by S:214-RQSR-215.
nc, nucleotide; length, nucleotide length; aa, amino acid; NTD, N-terminal domaine; S1, spike 1.
