Pango designation

The latest maintained Pango-lineage designations.

Novel lineages or lineage refinements can be suggested by filing an issue with the respective sequence names, as found on GISAID, and any supporting information such as a phylogenetic tree for the putative lineage.

Full details on how to suggest a new lineage can be found in the Pango lineage designation guide.

Nomenclature rules can be found in the Pango statement of nomenclature rules.

The lineage_constellations directory contains the mutations associated with each of the AY lineages. These are the mutations that were acquried along the phylogenetic path leading to the common ancestor of the lineage and remain conserved in the lineage (defined here as being in >70% of sequences designated to the lineage). This path is identified using the UShER phylogenetic tree. These constellations are different from those in constellations as they attempt to capture all of the associated mutations, not only the defining mutations for a lineage. These constellations are provided for reference and are not used by scorpio currently. However, they should be compatible with scorpio if researchers are interested in exploring them. Sites in the intermediate category drop in and out in the Delta clade so may be associated with the lineage but may be prone to artefacts.
