It's definitely interesting - and I can't quite figure out what's going on here. Is it selection driving the same deletions?Or do we have some homology among these sites in general, and then during a chronic infection they're more likelyto be cut out because of polymerase slippage, recombination, etc? When not deleted, how conserved are these sites in nucleotide space? Lots of interesting questions here - I definitely think they warrant a very close look since something is definitely goingon.

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

    What is up with that nsp6 deletion? Curious.... @Andrew Rambaut how's L452R growing in the UK?

    That nsp6 is cropping up a lot, isn't it. The B.1.525 I posted this morning has E484K and all three of the lineage defining B.1.1.7 deletions (plus Q677H - i.e. adjacent to FCS - possibly affects the O-linked glycs?).

    No coincidence that's for sure

    No. We are working on a project trying to define the convergent peak for all this. I would love you all's input once wehave put the guts together.
