Recipients on this medium are inferred from channel membership, not per-message addressing.

Also I have had some backtracking about the P323L coming up in monkeys - data looks dodgy apparently.

In context

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

Can I just loop back to an earlier chat: @Andrew Rambaut in A.23.1 (Uganda I think) I assume you don't see Doug and Phil (the mutation in nsp12)? So, the elevated number of changes in this lineage is due to a different evolutionary pathway facilitated by another 'enabling' mutation like Doug (or Phil)? Do you see mutations that arestructurally/functionally similar to Doug and Phil? I'm just wondering if this parallel evolutionary process provides some important clues?

It doesn't have Doug but it does have his brother Q613H. No Phil (a minority of them have nsp12 mutations but haven't dug into those yet). Does also have a bunch of NSP6 mutations in similar places to the deletion.

A.23.1 also has a cluster in the UK with E484K

Fascinating. So, D614G or Q613H (and perhaps linked mutations) push the virus down a particular evolutionary 'corridor' which then means that only certain subsequent mutations will follow?

Interestingly it seems that P681R arose after Q613H: [shared file(s): A.23.1_2021-02-02.tree.png]

Ha. So that parallels P681H in B.1.1.7?
