Distinct Patterns of Emergence of #SARSCoV2 Spike Variants including #N501Y in Columbus, Ohio

“We report here the emergence in Columbus, Ohio in December 2020 of two novel SARS-CoV-2 clade 20C/G variants. One isolate, that has become the predominant virus found in nasopharyngeal swabs in the December 2020-January 2021 period, harbors S p.Gln677His, membrane glycoprotein (M) p.Ala85Ser (Q677H) and nucleocapsid (N) p.Asp377Tyr (D377Y) mutations. The other isolate contains S N501Y and ORF8 Arg52Ile (R52I), which are two markers of the UK-B.1.1.7 (clade 20I/501Y.V1) strain, but lacks all other mutations from that virus. It is also from a different clade and shares multiple mutations with the clade 20C/G viruses circulating in Ohio prior to December 2020. These two SARS-CoV-2 viruses emerging now in the United States add to the diversity of S gene shifts occurring worldwide and support multiple independent acquisition of S N501Y (in likely contrast to the unitary S D614G shift) occurring first during this period of the pandemic.”
