This tool is designed to use Blast and phylogenetic methods in order to identify the possible designation as a WHO SARS-CoV-2 Variant of Concern of a nucleotide sequence.
Updated in December 2021:
- The scope of the tool was changed to detect only whether a submitted nucleotide sequence is SARS-CoV-2 variant of concern:
(* beta test, please provide feedback)
|WHO designation ||Pangolin lineage(s) ||Nextstrain clade
|Alpha ||B.1.1.7 ||20I
|Beta ||B.1.351 ||20H
|Gamma ||P.1 ||20J
|Delta * ||B.1.617.2 ||21A, 21I, 21J
|Omicron * ||BA.1 ||21K
|Omicron * ||BA.2 ||21L
For a fine grain classification of variants other online tools are availble: nextClade
and pangolin .
Note for batch analysis: The tool accepts up to 2000 sequences
at a time.
