From: Pango lineage designation and assignment using SARS-CoV-2 spike gene nucleotide sequences
Plot showing the number of mutations in the CSH for a given lineage as a function of the mutation frequency threshold (X) used to define the CSH. Lineages shown are those that contain > 20 designated sequences with complete spike nucleotide sequences and > 5 spike mutations. The lineages that correspond to the four main VOCs are coloured individually, whilst all other included lineages are shown in green
