Maternal Haplogroup T2?

[nicole2496]

I have the maternal haplogroup T2. What does anyone know about this haplogroup? I can't really find any information about it.

I've gone and moved this thread to the appropriate section in mtDNA Haplogroups, so you are more likely to get a response :)

Are you like T2, T2? No subclades? Have you done further testing or checked it manually to see which subclade you belong to?
T2 is pretty broad.

Yes, all it says is T2. And how would I check for that manually? Do I just look at the data and find the SNP associated with that haplogroup? Because I have 11812G, and it says that that is associated with the T2 haplogroup.

Manually checking your data might be a bit challenging at first. Since you don't have any subclade or even a close match, checking every mutation for each subclade is time consuming and unnecessary. There are some pages where you upload your rawdata and they make assumptions. They are mostly accurate.
Where did you get tested? If you were tested with 23andme anytime after August, 2017 you can use new james lick page: dna.jameslick.com/mthap-new/

I tested with Ancestry, then I came across the site WeGene. So I uploaded my raw data to WeGene and then it said the maternal haplogroup is T2. I looked for the other mutations for each subclade of T2 and I don't have anything that matches them. I have 11812G which is for T2 and that's it, I don't have anymore matches beyond that.

T2* is essentially a West Eurasian haplogroup. Centered around Near Eastern, European and Caucasian maternal lineages. Nevertheless, the origin of T2b* seems to be a predominant Western/Central European haplogroup. Highest frequencies more prevalent in North Italians from the looks of it. Has been proposed that it is essentially an early Neolithic haplogroup that took refuge in the Near East during the Last Glacial Maximum (LGM) when it coalesced into a European specific mutation with innumerous sub branches/mutations. I researched my own mtdna (T2b3b); seems to be mostly Western European in origin.

Here is a scholarly article detailing the distribution of T2b*:

Haplogroup T2 (Figure S2), which dates to ∼21 ka ago, forms the major part of haplogroup T in terms of both frequency (predominating in western Europe, where it reaches ∼80% of total T lineages) and number of basal clades (at least nine, T2a–T2i). T2 is most frequent in Mediterranean and central and western Europe (∼8%, reaching almost 13% in northern Italy) but is also common (up to ∼10%) in some parts of the Levant and Iran. The whole-genome data show that about three-quarters of T2 variation in Europe can be classified into subclades through the use of HVS-I data, but less than half of the variation in the Near East and the Caucasus can be so classified.

By far the most common subclade within T2 is T2b, which is predominantly European, dates to ∼10 ka ago, and is quite star-like, with 13 named basal subclades (T2b1–T2b24), along with at least seven more unnamed subclades represented by only two complete sequences each, as well as a large number of (mostly European) paraphyletic T2b∗ lineages; no doubt many more subclades remain to be discovered. The larger of the T2b subclades date to ∼6–9 ka ago and are predominantly European, albeit with evidence of substantial gene flow into the Near East. A clear example is T2b4, which includes a small derived subclade, identifiable in the HVS-I network, which appears to have spread into the Gulf region and further into Nepal, but the existence of several other lineages (either matching common and diverse European lineages or those derived from predominantly European clusters) throughout the HVS-I network points to multiple migrations into the Near East from Europe. Near Eastern matches usually include eastern Europeans, suggesting a probable route back into the Near East. The early presence of T2 in Europe (even with the assumption that it arose in the Near East) suggests that ancestors of T2b might have been present in Europe well before the age of T2b itself, at any time back to the LGM, although T2b seems to have been dispersed within Europe during the early Neolithic period. T2b has been identified in Neolithic remains from Italy, Spain, France, Germany, and Sweden.33–35,47–49 It has also been identified in a Mesolithic Pitted Ware sample from Scandinavia, dating to 4.0–4.8 ka ago, during the period of coexistence with Funnel Beaker farming communities, suggesting the possibility of assimilation of lineages from the Neolithic period into the hunter-gatherer population.46 [...]

For people who have tested T2 at FTDNA, the admins of the long-silent T2 project there have just restored the myGroups format [on a 30-day trial basis] and its "Activity Feed" -- the internal forum, available to the roughly 2500 project members. So there is a bit of chatter, there, that has been missing for some 2 1/2 years.

I realize that the OP did not test at FTDNA, but somebody who has done so might see the thread.

I am only T2b, even after doing full sequence. I'd kind of given up on it giving me any kind of specific info.

I only found out yesterday, so I've been looking online all day for more information about this haplogroup. I just hate that my haplogroup is just T2 and nothing else because while it does give a bit of an idea of where my maternal line started, it doesn't really get too specific. I feel like the other haplogroups have much more information and the T haplogroup just don't get much attention.

there's also this, a very recent mtDNA wiki, for mtDNA enthusiasts:
http://mtdnawiki.com/t2/ -- a couple of other pages in the wiki could be useful too.
If you are indulgent toward typos and don't mind the sales pitch, it could be an additional source of information.

Aldric,

Where did you find that tree chart of mtDNA group T? Are those samples that tested positive for said mutations? I'm in the T2b2b area - my MDKA for my mtDNA is from Ireland and T2b2b seems to be mostly Irish, Isles, and Scandinavian.

Cheers,
Charlie

Nicole,

I'm T2b2b - so hello from a fellow T member ;-). I've found that my particular group T2b2b seems to be (based on current samples and reported most-distant-known-ancestors) is most common in Ireland (which matches up with where my maternal line is from - from the Western parts), but also has a decent presence in Scandinavia. Also an interesting ancient sample we both match because she is positive for T2b - is the female "Viking warrior" skeleton from Birka, Sweden https://en.wikipedia.org/wiki/Birka_female_Viking_warrior

I haven't had full sequence done yet - I got my mtDNA assignment through National Genographic Geno 2.0 test. It seems to me that the maternal haplogroups are so old and widespread (and they don't mutate nearly as often as Y-DNA - making your matches just that much older) that it is hard to narrow down origins. I know that they have found T2b in many ancient remains... from Pompei to many of the Bronze Age remains...

How far have you traced your particular maternal line back? I have made it back to my 3rd Great Grandmother Bridget Dana born in Ireland, but I have been unable to find her parents. I am hoping that eventually when I get full sequence done... it nets me a slightly "closer" match with another tester with an Irish MDKA...

For fun you could try looking up papers with ancient remains with samples of T2 and T2b... I recently was in the ancient DNA from Poland coming soon thread in the Ancient DNA area... and one of the recent posts from perhaps Roman era Poland had some T2b...

For me I already had a very strong connection to Ireland through both my Mother's father's and mother's (maternal line). Her paternal Grandfather was 100% Irish and married a lady of Gaelic Irish and Scots Highlander/Hebrides descent from Ontario, Canada. My father's side also has plenty of Scots and Irish (sometimes Scots-Irish - Scots who settled in Northern Ireland before coming to America!)... my Mom has 2nd cousins in Ireland and 3rd cousins in the Scottish Highlands/Hebrides and I am planning on testing her autosomal per the FTDNA family finder test here soon :-)! For the record here is my autosomal map - I think I saw yours in the other thread - you are very Greek right? 20955

Cheers,

Charlie

Aren't we T2b* ? The T2b-asterisks? (did you upload to GenBank? please do if you haven't)
