Figure 1. Identification of genome targets to differentiate between B.1.1.7, B. 1.351, P.1, and other SARS-CoV-2 lineages.

Figure 1.

(a) Location on the SARS-CoV-2 genome where the targeted deletions in the ORF1a gene at amino acid positions 3675-3677 (Δ3675-3677) and the spike gene at amino acid positions 69-70 (Δ69-70) occur, (b) The Nextstrain ‘global build’ (nextstrain.org/ncov/global) accessed on 2021-01-22 showing the phylogenetic representation of 4,046 SARS-CoV-2 genomes colored by the presence of deletions at amino acid positions ORF1a 3575-3677 and spike 69-70. (c-f) Zooms of large SARS-CoV-2 clades, which include the variants of concern B.1.1.7, B. 1.351, and P.1, containing one or both deletions. A list of SARS-CoV-2 genomes used in the analysis is available in Source Data Fig. 1.
