Normally I would ignore singlet recombinants, but these seem quite unusual. The original lineage has only been detected in a traveler to the USA (New York) from Qatar. Yet there are already two recombinants of this lineage on two different continents, meaning that this lineage has spread to three continents and already undergone two recombinations with fast-growing, recent lineages. It seems very likely to me that this lineage is widespread and growing rapidly in some unsampled part of the world.

Great catch Ryan! i ve modified the query of the non recombinant( DONOR ) to exclude its recombinant : new query: G22111T, G22131C,T3565C . It is enough to remove T3565C to catch all the four samples.

FedeGueli commented 3 months ago

Second sequence for the KP.3 recomb, this time from... Spain! (it seems everything fast is there right now)

corneliusroemer commented 3 months ago

Hah, I independently found this LB.1 + 190T / KP.3.2 recombinant:

hCoV-19/Sweden/S-1260950467R4/2024|EPI_ISL_19136338|2024-05-02
hCoV-19/Spain/CT-HUVH-E46508/2024|EPI_ISL_19165017|2024-05-20

Breakpoint between 22132 (S:190T) and 22599 (S:346T) - fascinating that it chose to get rid of 346T, as if that wasn't useful in KP.3

The donor is KP.3.2 by the way, as it contains C22858T

Brave Browser 2024-05-28 18 45 24

Query is: G22111T,G22131C,C22858T

FedeGueli commented 3 months ago

Same thought on 346T .

ryhisner commented 3 months ago

Yeah, I've thought from the beginning that KP.3 probably would not get R346T. It's always been bad on an N450D background, and Q493E is in the same region as both residues, making me suspect KP.3 has found a way to evade antibodies without suffering the ill effects of the R346T-N450D combo.

Two more sequences from the non-recombinant branch (with the Qatar travel sequence) showed up today: one in Wales and one in California. Both with collection dates in May. EPI_ISL_19177079, EPI_ISL_19177989

EDIT: Usher makes it look as if the new California sequence sits between the KP.3.2 and KP.2 recombinant, but that can't be right. It has G19669A (ORF1b:G2068R)—which comes from the parent LB.1 lineage from which the KP.3.2 recombinant springs—but NOT C22858T, S:Q493E, or S:V1104L which Usher seems to think both it and the Canadian sequence have, though neither have any of those.

Can someone tag Angie Hinrichs on this? I'm not sure why, in this case, Usher is ignoring so many mutations/non-mutations, and I can't seem to tag her here for some reason.

2 more LB.1 x KP.3.2 recombinant in Spain. Interesting

@HynnSpylor - hah I just saw this as well - I hadn't read your comment before.

Can someone do a proper recombinant analysis, with breakpoints? Then we can designate it!

Very interesting Spike, combination of the 2 fittest lineages around, and spotted in 2 countries, and in sentinel surveillance over time, so unlikely this is unreal.

corneliusroemer commented 3 months ago

Ok I'll do it:

It's a KP.3.2 recombinant because it has C22858T

On the other side it's an LB.1.2.1.

Breakpoint between G22131C (S:190) and G22599C (S:346)
