#PSA for SARS-CoV-2 variant surveillance folks:
We've just released a new Nextclade dataset that can detect BA.2.75, even if there are lots of dropouts and sequencing artefacts as shown in the screenshot where many sequences have dropout in the RBD. 1/

BA.2.75 has 16 nucleotide mutations in addition to the branch it attaches to (BA.2 + 25416T, which is incidentally the one that BA.2.12.1 is also on). That's why it can be confidently called even if sequence quality is problematic. 2/
If you want to browse through the zoo of Pango lineages, what mutations they have and how they relate, you can have a look at this Nextstrain tree.
Ironically, BA.2.75 seems to continue the flip-flopping of the S:69/70 deletion highlighted in yellow. 3/
