@Robert Garry It's the insertion P in PRRA

In context

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

P681H is also VERY interesting....how common is this?

There is an ORF8 stop at amino acid 27 and then a number appear after that suggesting it has become non functional.

@Robert Garry Why do you say that?

Any thought if it would likely be an immunecompromised patient - could a weak immune response enhance selection for escape? Or do we know of any asymptomatic shedders - which would allow for the transmission if the person was out and about?

@Robert Garry Would be surprising if it didn't affect cleavage...

It's a little weird in that respect - the patient above essentially has no - or very limited - humoral immunity, but thesignatures still look like immune escape - or maybe something else is going on. So yes, even immunecompromisedpatients can shed viruses that may have signatures of immune escape.

@Robert Garry Ooh. Missed that.

@Robert Garry That's the one I'd be concerned about.
