Discussion: To further differentiate Alpha, Beta, Gamma, and Mu, other mutation sites in the Spike protein like 69-70 deletion or 144 deletion, 242-244 deletion or K417N, R190S or K417T, T95I or R346K can be detected respectively.
SARS-CoV-2 Delta Variant Displays Moderate Resistance to Neutralizing Antibodies and Spike Protein Properties of Higher Soluble ACE2 Sensitivity, Enhanced Cleavage and Fusogenic Activity.
Introduction: B.1.617.1 contains additional substitutions in the NTD (T95I), the NTD antigenic supersite beta-hairpin (G142D and E154K), within the S1/S2 cleavage junction (P681R), and in the S2 subunit (Q1071H).
Prediction of SARS-CoV-2 Variant Lineages Using the S1-Encoding Region Sequence Obtained by PacBio Single-Molecule Real-Time Sequencing.
Result: Taken together, the most frequently missed mutations were G142D (n = 11), E156G, 157del, 158del (n = 6), N501Y (n = 6), S477N (n = 5), T95I (n = 3), V130F (n = 2), and E484K (n = 2).
Result: The missing mutations were not located in the same region as previously, but rather over the amplicon NC_045512.2:21743-21961 (T95I, V130F, G142D, E156G, F157del, and R158del, A222V).

Evolution, Mode of Transmission, and Mutational Landscape of Newly Emerging SARS-CoV-2 Variants.
Introduction: B.1.526-E484K and B.1.526-S477N share the characteristic spike protein mutations L5F, T95I, D253G, D614G and either A701V or Q957R, along with either E484K or S477N.
Introduction: Pseudoviruses were constructed containing S477N or E484K alone, or containing all five signature mutations (L5F, T95I, D253G, A701V and E484K or S

Result: Alignment analyses showed that, with respect to the Wuhan-Hu-1 Reference Genome NC_045512.2, SARS-CoV-UNIBS-2 AP66 consensus sequence displayed 6 nucleotide substitutions (C241T; C3037T; C14408T; T21784G; C21846T; A23403G) leading to 4 non-synonymous changes (ORF1ab polypeptide: P4715L; S protein: N74K, T95I, D614G).
