Result: For each sample, a total of nine mutations were found in the spike protein: H69-70-, Y144-, N501Y, A570D, D614G, P681H, T716I, S982A, D1118H.
Discussion: The large number of genomic mutations associated with B.1.1.7, including SNPs (A570D, D614G, P681H, T716I, S982A, and D1118H) highlight the need to rapidly distinguish these subtle mutations in emerging VOCs.
Ultrapotent miniproteins targeting the SARS-CoV-2 receptor-binding domain protect against infection and disease.
Result: Accordingly, we evaluated the activity of LCB1v1.3 against a B.1.1.7 isolate containing deletions at 69-70 and 144-145 and substitutions at N501Y, A570D, D614G, and P681H, and against a recombinant WA1/2020 strain containing key substitutions present in the B.1.351 and B.1.1.28 variant strains at residues E484K, N501Y, and D614G.
Immune Evasion of SARS-CoV-2 Emerging Variants: What Have We Learnt So Far?
Introduction: The first variant Alpha or B.1.1.7 that raised global concerns about increased transmissibility and potential immune evasion harbors seven missense mutations (N501Y, A570D, D614G, P681H, T716I, S982A, D1118H) and three deletions in spike (69/70del and 144del) (Figure 3).
A Comprehensive Molecular Epidemiological Analysis of SARS-CoV-2 Infection in Cyprus from April 2020 to January 2021: Evidence of a Highly Polyphyletic and Evolving Epidemic.
Abstract: Genetic analysis of whole SARS-CoV-2 genomic sequences of the aforementioned lineages revealed the presence of mutations within the S protein (L18F, DeltaH69/V70, S898F, DeltaY144, S162G, A222V, N439K, N501Y, A570D, D614G, P681H, S982A and D1118H) that confer higher transmissibility and/or antibody escape (immune evasion) upon the virus.
Introduction: Furthermore, mutations/deletions in the S-protein, such as L18F, DeltaH69/V70,
Introduction: VOC, 202012/01) with multiple S protein mutations (deletion 69-70, deletion 144, N501Y, A570D, D614G, P681H, T716I, S982A, D1118H) spread rapidly across South East England and London.
The Antigenicity of Epidemic SARS-CoV-2 Variants in the United Kingdom.
Introduction: Since December 2020, the VOC-202012/01 (VOC-202012/01 variant, including multiple mutations 69-70del, 144/145del, N501Y, A570D, P681H, T716I, S982A, and D1118H) has been increasing rapidly.
Discussion: Eight of the 17 mutations in the VOC-202012/01 variant are located in the spike protein, including 69-70del, 144/145del, N501Y, A570D, P681H, T716I, S982A, and D1118H.
Antibody Cocktail Exhibits Broad Neutralization Activity Against SARS-CoV-2 and SARS-CoV-2 Variants.
Introduction: The recent emerging variants of concern observed in the United Kingdom (B.1.1.7 with mutations N501Y, A570D and del69/70), South Africa (B.1.351 with mutations K417N, E484K and N501Y), Brazil (P.1 and P.2 with mutations K417T, E484K and N501Y) (Long et al.) and India (B.1.617 with mutations L452R and E484Q) (Cherian et al.) initially respond more tightly to ACE2 and appear to be more infectious to human (Laffeber et al.; Tian et al.).
Result: Mutations in B.1.1.7 (including 69-70del, Y144del, N501Y, A570D, PMID: 34245452

Discussion: The set of signature variants includes 8 changes from S protein: deletion 69-70, deletion 144-145, N501Y (A23063T), A570D (C23271A), D614G, P681H (C23604A), T716I (C23709T), S982A (T24506G), D1118H (G24914C).
Evolutionary insights into the furin cleavage sites of SARS-CoV-2 variants from humans and animals.
Discussion: Moreover, this mutation is also a characteristic of the newly emerged SARS-CoV-2 variants, which are defined by multiple mutations in the S glycoprotein (Delta69-70, Delta144, N501Y, A570D, D614G, P681H, T716I, S982A, and D1118H).
