    Z2534 branches at present

    I have created this new thread to avoid to interfere with FGC results, I think it's better to discuss in the correct thread when it is about specific SNP.

    Here is how I see the Z2534 branches at present:
    1. Z2534>Z2185 (I'm using Z2184 in the Big Y results, as it is currently phylogenetically equivalent to Z2185, which is not covered by Big Y).
    2. Z2534>L226.
    3. Z2534>DF73 (so far only derived in people of Iberian ancestry, and there are no known DF73+ testers in FG, Big Y or Chromo 2).
    4. Z2534> four new SNPs and four new indels shared by two Big Y testers, one of whom (MacKenzie) is L643+ and the other (Whitehead) L643-; the SNPs are 6103210 A>T, 7654538 C>T, 9101775 A>G and 14049507 T>G.
    5. Your own new SNPs; you are of course Z2534+.
    6. New SNPs from Penaloza (Big Y), who is also Z2534+.

    Since I can't see any shared new SNPs among branches 4, 5 and 6, the new SNPs should all be downstream of Z2534. However I'd prefer to confirm this with more results.

    I'm afraid that I would not have any other reference to compare with or I didn't see it. I'm still waiting for BIG Y, it might help to identify with a bit more of accuracy in general the new SNPs and might help to cross-check with other results at some stage.

    Among these 50+ new SNPs, how can we determine which ones are immediately below Z2534 in a specific order? I think that I partially have the answer, by cross-checking with other results I'd say, the more people we have the more it is accurate. I suppose that the most difficult exercise is to know which ones are the most recent and which ones are the core underneath Z2534.

    Joss, thanks for moving the thread.

    I suspect that we will discover that there are groups of phylogenetically equivalent SNPs which we won't be able to separate. All we can do is compare results, using such tools as are available, like the spreadsheets maintained by Mike W, Dennis W, Alex W and others, and then recheck the raw data if something shows up.

    Re the Z2534 branches in my previous post, Penaloza, who is apparently of Iberian origin, is derived for the following SNPs: Z2189, Z2190, Z2191, Z2195, Z2197, Z2198, Z2199, Z2201 and Z2202.

    These are part of a larger group of SNPs, numbered consecutively from Z2187 to Z2206, found in 1000 Genomes data in two or three persons who were Z253+ DF73+. DF73 is downstream from Z2534. Penaloza is Z2534+ but DF73-.

    So the above nine SNPs are positioned above DF73, and very probably between Z2534 and DF73, as they have not shown up in the results of other Z2534+ persons so far. DF73 remains a terminal SNP at this stage.

    Seven of the above nine SNPs are available for a la carte testing from FTDNA. Other Z2534+ DF73- people, especially those of of Iberian ancestry, should consider testing for one or more of these SNPs.

    Perhaps the Big-Y Novel Variants trial tree that I have constructed for the Big-Y data is relevant.

    Big Y has finally arrived this evening, would be interesting to compare both Big Y and FGC.

    Make sure to give permission to Mike to share it on L21 group. Regarding comparing the two. I have a basic command script that takes the "positions" of novel SNP's in BigY and see if they show up in BigY variants.vcf file.

    Yep, it's done last night, uploaded this morning!

    I got an email from Britains DNA this afternoon, I noticed that they have changed from S218 (Z253) to S868 (Z2534) which makes sense. However, I have noticed a possible mistake in the ISOGG tree as S868 has been recorded as S686, I suspect a typo...

    With the change, BritainsDNA advised the following, there is not a big change in the narrative, I have highlighted what's new.

    Subtype
    Your subtype is R1b-S868
    Your S868 subtype was recently discovered using Chromo2, so its distribution is not yet understood. It belongs to the larger S218 cluster, which - without the downstream S168 marker -
    includes Scottish and English representatives and, intriguingly, more Spanish than any other S145 subtype. It is too early to be certain what this means, but might indicate an Iberian connection at some point. You may carry markers that further define your subtype, but do not yet appear on our tree. You will find these in your genetic signature.

    I had a look at the RAW Data, there is a good number of SNP who became "No Call", I haven't checked in details.

    Regarding the maps and other features, there is no change, and their phylogenetic tree remains the same without including S868/Z2534, there may be some change at some stage during the weeks/months.

    In addition, my mtDNA has been displayed this afternoon for the first time since I placed the order las october, then removed for some reason. However, I had the time to see that they have named M30 as Gange.

    Dennis, your spreadsheet is very helpful, as it includes FGC and Chromo 2 results as well as Big Y. Mike's Tree Discovery spreadsheet is also extremely useful. I have used these spreadsheets, your Z253 Research Tree and the Chromo 2000 public results to further review the branches of Z2534 and have re-checked the raw data and Big Y coverage where relevant.

    So here is the current state of play for Z2534, based only on SNPs. My intention was to develop an SNP testing approach for people who are found to be Z2534+, which means that we need one reliable SNP per branch which is available for a la carte testing. I think the branches are as follows:

    1. Z2185, which is numerically the largest branch. Z2185 appears to be phylogenetically equivalent to Z2184 and Z2182 at present. Z2185 should be the first SNP for which a Z2534+ person tests, unless he has a good STR match to one of the other branches. Z2185 is included in Big Y, but as its alias of CTS9975.

    2. L226, sometimes referred to as Irish Type 3, which as far as I am aware remains a well-recognised clade on STR results at present.

    3. Z2189, which leads to DF73. There are a number of SNPs which at present are phylogenetically equivalent to Z2189, but I have selected Z2189 as the marker for this branch because there are already a couple of a la carte Z2189 tests under way, one in a DF73+ person and one in a Z253+ Z2534+ DF73- person of Iberian ancestry. We already have a Big Y result which is Z2189+ DF73- in another person of Iberian ancestry, and the two DF73+ persons in the 1000 Genomes Project were Z2189+ as well. So DF73 will drop down a level if the Z2189 results are confirmed.

    4. This branch is defined by four unnamed SNPs: 6103210 A>T, 7654538 C>T, 9101775 A>G and 14049507 T>G. These SNPs are shared by two Big Y kits, both of which are Z2534+ and one of which is L643+, thus dropping the position of L643 down a level.

    5. Joss' branch, which I think should be defined by FGC8244+. This was found in his Full Genomes results and is also derived in one of the FGC references, HGO2771 (I'm not sure of the source of this reference, as the name doesn't fit for either the 1000 Genomes Project or the Personal Genomes Project as far as I am aware). We don't know which of his novel SNPs are private at this stage, but FGC8244 should turn out to be public in due course.

    6. Kiely has his own branch at present, with over 30 novel SNPs in his Big Y results, as well as being Z2534+ and negative for the SNPs which define the other Z2534 branches. Again, there is no way to tell at present which of these SNPs are private SNPs.

    7. S27687 is derived in two Z2534+ results in the Chromo 2000 speadsheet of results and negative in all other Chromo 2 results which are accessible. These two kits are negative for the other SNPs downstream from Z2534 which are included in Chromo 2. Unfortunately S27687 is not included in the Big Y coverage of the Y-chromosome.

    8. CTS6458 is derived in one Z2534+ Chromo 2 result. However it appears to be a recurrent SNP, as there are four more derived results in Chromo 2 distributed across 4 other haplogroups. Despite this, it may still be useful in sorting out the branches of Z2534.

    I have omitted S1984 (aka PF810) from the above analysis. It is causing confusion, as FTDNA report some results as positive (T>A), while in Chromo 2 all the Z253+ results but one are derived, leading to the conclusion that the one ancestral result represents a back-mutation (which may therefore be genealogically useful). However, S1984 has a mix of ancestral and derived results in Chromo 2 across 23 other haplogroups, including four other L21 clades. So I think this SNP is best disregarded.

    Comments, criticisms and corrections are very welcome.

    Sorry, Kiely is Z2534- on checking his raw data and previous Sanger results, so branch #6 above can be deleted.

    I also count five other STR spreadsheet varieties or unassigned individuals who are Z2534+ and have not fully tested for downstream SNPs yet, so there are probably more Z2534 branches out there. In terms of age, Z2534 is at least three SNP levels above L1066.1, so I would expect considerable genetic diversity in this clade.

    I ordered BigY for my brother today, we're the other Godfreys (167477 and 304969) in the Z253 project. The third Godfrey and currect Z2534* on the Big Tree (106724) is a 60/67 match with us and disappears as a match at 111 (I think he was something like 99/111). Our paper trails going back to the 1600s do not cross and our lines are from separate parts of the USA and England so our common ancestor is far enough back that I think the comparison of our results will break up 106724's currently private SNPs. i believe that GD is also great enough to potentially qualify common SNPs as public SNPs at ISOGG. I'll make sure to get the raw data to Alex once it is available. My current Z2534* status comes from Geno 2.0 and the Z253 pack.
