SARS-CoV-2 variants of concern and of interest
A new poster showcasing the genes and ORFs (open reading frames) of each of the 13 WHO variants. One of these posters appeared in the March/April 2022 issue of American Scientist.
WHO skipped nu (ν) and xi (ξ)? Yes, WHO did.
On these posters, the sequence of each variant is drawn as a path. The length of the path is proportional to the size of the genome. Every fifth base is drawn as a circle whose color is based on the GC content (fraction of guanines and cytosines). The path curvature is proportional to the repeat content and the direction of curvature is determined by whether the GC content is lower or higher than average. Data for all variants can be downloaded from NCBI Virus.
Can you untangle the ball of confusion?
mutations profiles of each variant
Mutation profiles of each WHO SARS-Cov-2 variant, with a focus on unique mutations. The poster is a visual story of how to tell a story and shows the benefits of rescaling each ORF and gene based on the density of unique mutations.
of concern
Genomes of 13 WHO variants of SARS-CoV-2. The first sequence is the original Wuhan-Hu-1 strain used as the virus' reference genome.

matrix of 56 genomes
Genomes of 56 fully sequenced isolates of the Sudden Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Each genome is drawn as a path. The length of the path is proportional to the size of the genome. Every fifth base is drawn as a circle whose color is based on the GC content (fraction of guanines and cytosines). The path curvature is proportional to the repeat content and the direction of curvature is determined by whether the GC content is lower or higher than average. Genomes are labeled by sample origin, date, accession, size (in bases) and the number of base differences relative to the first published SARS-CoV-2 genome (MN019529), which appears first on the poster.
Completely sequenced SARS-CoV-2 isolates as of 8 March 2020 from China National Center for Bioinformation and NCBI. Poster updated 17 March 2020.

The length of the path is proportional to the size of the genome. Every fifth base is drawn as a circle whose color is based on the GC content (fraction of guanines and cytosines). The path curvature is proportional to the repeat content and the direction of curvature is determined by whether the GC content is lower or higher than average. Genomes paths are centered and layering order of is determined individually for each base by the difference between local GC content and the average value of 0.38.
Genome of first sequenced isolate
The genome of the first fully sequenced isolate of Sudden Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) is drawn as a path. The length of the path is proportional to the size of the genome. Each base is drawn as a circle whose color is based on the GC content (fraction of guanines and cytosines). The path curvature is proportional to the repeat content and the direction of curvature is determined by GC content.
