New Subclade Announcement: E-Y140463

I am personally very excited to announce the recognition of new subclade by YFull! The subclade is called E-Y140463, and it is downstream E-Y17226. 

Many thanks to the other Big Y tester, his admin, and Judy & Igor for helping me order my Big Y!

It is a single SNP subclade, defined by the SNP Y140463.

With both kits, YFull's age estimate for the TMRCA of this subclade is approximately 500 years ago. Given the value spread for genetic distances within this group, this may be a good estimate, though more testing is needed to confirm. 

This subclade is associated with group B21, B22, and B99 in the Y-DNA results page here. If your kit is in one of these groups, and you would like to confirm that you are positive for the SNP defining this subclade, please send an admin an email. 

According to the countries of origin for project members in group B21 and B22, this subclade looks to be primarily centered around Poland, with many members having lines from Belarus and Lithuania as well. There is also a member with a line from eastern Germany, near the Czech border. Due to the spread and the age of this subclade, it will be difficult to make a confident guess as to its geographic origin.

Our next steps for research of this subclade are:
1) To have another member Big Y tested to refine the age estimate and to perhaps discover a new subclade downstream E-Y140463.
2) To get the remainder of B22 SNP tested for Y140463.
3) To have B99 members get STR upgrades to see if we can predict them Y140463+. 

You can see the new subclade here. If you have any questions about this subclade, please post a comment or send us an email. Thanks!
