T2 mtDNA

  • 1646 members

About us

This project is for anyone with mtDNA belonging to Haplogroup T2. Nearly 10% of Europeans can trace their maternal ancestor to Haplogroup T. The haplogroup spread into Europe with the early farmers from the Near East.

If you belong to T1, please join the T1 project instead.

If you are defined as T only, please join the T mtDNA other (not T1 or T2) project instead.


Subclades and Coding Region results

The T2-project will assign members to subclades according to these research results. However, without the full mitochondrial sequence (FMS) results it may not be possible to put your results into a subgrouping other than T2. If you have done a Full Sequence test (FMS) it is helpful for us if you open up your Coding Region results to be viewed by project administrators. It is your choice whether you permit us to look at your FMS results, but these are most often necessary to assign you to subclades. Only in very rare cases do these reveal any potential medical issues, and most testers choose to include these for mitochondrial DNA-project administrators. Your results, of course, will remain absolutely confidential.

To open the CR results:
  1. log in with your kit number and password
  2. go to Manage Personal Information and the tab called: Privacy & Sharing
  3. find the T2-project on the list
  4. tick/check the box to show CR-results for the T2-project
  5. click "save" at the bottom of the page

Information about your ancestry

mtDNA is inherited strictly through the direct maternal line.

To learn more about the origins of the various subclades of mt-haplogroup T, it is important that all T2-members fill in their ancestral information under Ancestral Location. Enter full name, appr years of birth/death, place, county and country. If unknown because of adoptions or other, please explain under "maternal ancestor" in "User Preferences". Also note that your direct maternal ancestor is the name of your mother's mother's mother etc, through a female line only - it is always a woman. Please also plot the location of this direct maternal ancestor on the map.

We will be updating the "country of origin" if entered in your user information on the mtDNA results webpage. If you have questions, feel free to contact the group administrators.

Connecting to other mtDNA T members

There is a Facebook mtDNA T-discussion group where anyone can sign up, share and ask questions.

If genealogical DNA testing is new to you, then you might find it useful to review some of the information provided on the ISOGG Wiki, click here.

There are also some free webinars about genealogical DNA testing that you can view and/or participate in here.



Contribute to Research

Have you done the Full Mitochondrial Sequence (FMS)? Are you still “just” T, T1, T2 – or other udefined groups? Maybe no one has done any research on just your specific mtDNA mutations yet.

For the scientists to evaluate all possible SNPs found in your sequence and define new haplogroups/subclades, they need access to more data.

a) Donate to GenBank

Everyone with a Full Sequence test (FMS, FGS, Full, “Mega”) can donate resultats to GenBank and contribute to research.

How?

You need to log in and download your mtDNA results as FASTA-file.
Send it to Ian Logan, who will help you to continue the process.

Detailed description here: Ian Logan's website.

b) Donate your sequence to mtDNA-research via FTDNA

Testers who have done the mtDNA full sequence test (FMS) at FTDNA are asked to fill in a “New Survey”.

Fill in countries of origin, languages etc for your ancestors.

If you already donated to GenBank please also fill in GenBank accession number.

Then they ask permission to use your results in research of new haplogroups, and to be allowed to release your sequence with national origin to the public GenBank database. This happens if they use your sequence in a future scientific paper.

Why?

You will contribute to the discovery of further subclades of mt-DNA.
Results will be accessible to researchers worldwide. Your results are anonymous, only the contact person at GenBank/FTDNA will know who you are.

Behar et al published a paper in 2012 based on donated sequences. Read more at mtDNA Community.
