UK BA.2 (+G12163T) lineage with S:F186S [1k seq]

[corneliusroemer]

Spotted a UK BA.2 (+G12163T) lineage that has an S1 mutation S:F186S and makes up about 0.6% of UK BA.2

Seems to have a bit of a growth advantage over other BA.2* and BA.2+G12163T

Seems to slowly appear abroad as well, probably exported from UK.

Thanks @corneliusroemer Agree that the clear geographical focus of this clade in the UK combined with a steady increase in proportion of UK BA.2 sequences warrants a designation. We've added this as BA.2.22 to start on the branch with T22119C (S:F186S)
