JN.1.39 + T111C [5' UTR] (469 seq, Apr 6) #2554
Comments
The usher tree is likely confused. Some JN.1.33 seqs have position 111 missing coverage, so usher categorize them as not having T111C, therefore it places T111C after S:A67V. However no JN.1.33 seq has 111T, suggesting that those 111 missing coverage seqs do have T111C and JN.1.33 is actually a sub-branch of JN.1.39, or a recombinant involving JN.1.39 as its 5' parent. |
There is one sequence with G2782T, T111C, C5512T but S:67A, EPI_ISL_18982930 from China. The sequence suggest the correct order shall be JN.1.39->T111C->C5512T->S:A67V, |
cc @corneliusroemer @AngieHinrichs could you look at this? it is from some weeks @aviczhl2 is raising the issue of the T111C , G2782T being splitted in JN.1.33 and JN.1.39 , to me is hard to reach a consensus on this. |
Mutations next to deletions are frequently misread, so I'd be surprised if there aren't numerous sequences with G2782T, T111C, C5512T, and S:67A. But the fact that there are 350 sequences with C5512T but without G2782T, T111C, or S:A67V makes it clear these two lineages are very unlikely to be directly related unless it's through recombination. |
Yeah I also think it is likely a recombinant. China is not submitting much sequences so lineages with S:67A is likely to have very few seqs due to it cannot compare with S:67V. I just wanna point out the correct order of the mutation shall be JN.1->G2782T->T111C->C5512T->S:A67V as there are no seq of 5512T+[exactly-1-of: 2782T, 111C, S:67V] |
Yeah, but there are hundreds of sequences with C5512T and not G2782T. C5512T had to come first on the JN.1.33 branch. There are zero sequences on the JN.1.39 branch that have C5512T. |
That's because they are placed to JN.1.33. |
They don't have S:A67V either though. And even if that's the case, it still doesn't explain how there are hundreds of sequences with C5512T but without T111C, G2782T, or S:A67V. |
1:There is a JN.1+C5512T branch (which is where "hundreds of seqs" come from) 3: There is a JN.1+T111C,G2782T,C5512T branch, and usher place them as JN.1+C5512T+G2782T,T111C. 3 is likely a recomb of 1 and 2, and if we don't consider recombs 3 shall more likely to be placed under 2. 4: S:A67V is a sub-branch of 3. |
it is branch 51 of sars-cov-2-variants/lineage-proposals#1089 |
the 456l branch with 1104L could be a recombinant ? |

Evidence
I find it intriguing that there are two large JN.1* lineages with the synonymous G2782T and the 5' UTR mutation T111C. The other lineage with both T111C and G2782T is JN.1.33, which also has the synonymous C5221T and S:A67V (C21762T). Both lineages appear to have a modest but consistent growth advantage (~10-15% weekly) over baseline JN.1* despite not having S:R346T, S:F456S, or S:T572I, the three major mutations that clearly confer growth advantages at the moment.
I suppose there are three possibilities here:
There has been no connection between these two mutations before. In fact, if you search GISAID for T111C and G2782T, the only sequences returned are from JN.1 and three Bat-CoV sequences collected in Yunnan, China, in 2020 (RmYN05, RmYN08, RsYN04).
T111C is on SL4 in the 5' UTR. It is paired with G101, which is a weak, non-Watson-Crick base-pair bond. T111C would create a much stronger C-G base pair, which could conceivably affect the stability of SL4 and perhaps have some unknown effect on viral fitness.

I aligned the nucleotide sequences for the 19 Bat-CoV sequences I could find on GISAID, and six of them had T111C (RsYN03, RsYN04, RsYN05, RsYN07, RsYN08, RsYN09). SARS-CoV-1 and murine hepatitis virus (MHV) also have T111C.
