Updated text: August 24, 2015 Tree for I-L621

I think you should be able to see the information on this tree. It shows the new I-A2512 branch. Probably there are more additions compared to the earlier I-L621 trees.

A fourth major branch of I-CTS10228 "Dinaric" and two new SNPs available for testing: Almost everyone in I-CTS10228 belongs to one of three branches: I-S17250, I-Y4460 or I-Z17855. But there are a few people who are CTS10228+ and S17250- Y4460- Z17855-. We now know that there is a fourth branch called I-A2512. Two people have done Big Ys which show that they belong to this group: kit 4605 from the "Jewish Dinaric" cluster, and kit N80837 who has Greek ancestry and is part of the Mediterranean Dinaric cluster. Kit 54093 has also received Y2512+ results from YSeq, he is also part of the Mediterranean Dinaric cluster and more specifically the New Mexico Dinaric cluster. Finally there is an anonymous sample (GS000018440-DID) from Chuvashia that was sequenced by the Estonian Biocentre and found to belong to I-A2512, see: A2512 (position 13203040) is available for testing at YSeq and people who have already received CTS10228+ and S17250- Y4460- Z17855- should test A2512. That is a very small number of people, most Dinarics do not need to test A2512, please ask us if you have any questions. Another novel variant at position 9853064 is shared by kits 4605 and N80837 and by GS000018440-DID but there is no test available currently. Finally, kit N80837 Greek ancestry shares the novel variant 18741220 with the Chuvashia sample GS000018440-DID but the Jewish Dinaric man kit 4605 does not have this SNP. 18741220 is available for testing at YSeq, it is called A7134 and it is recommended for the New Mexico Dinaric cluster and other members of the Mediterranean cluster, and anyone who has already received A2512+ results. You can see a new tree with these branches here:

And you can see some of the groups discussed here: I apologize in advance if I have made any errors in this post.
