News for G2a3a3a persons
Because no researcher has yet tested specifically for your G2a3a3a subgroup in their study, we have to confine the news to the more general G2a3a group.
We are also hampered in reporting news specific to G2a3a because the researchers have seldom tested for it. This situation is getting better, and there has been a tendency to see a few more studies testing for M406, your shared mutation, but disappointingly few.
To give a better idea of the percentage of G2a3a (M406) in populations for which marker samples are available, I have created a listing showing the number of samples with a 21 value for DYS390.
We know from the information in the project that a high percentage of the men with 21 for DYS390 are actually your G2a3a cousins. So this chart gives some idea of how common G2a3a is in many European locales.
There was one exceptional study done this year worth pointing out to you.
The 2011 Balanovsky study found 12% G2a3a-M406 among the Lezgins but almost no M406 anywhere else in the Caucasus Mountains area. This is an area of the world with high levels of haplogroup G otherwise. So it is rather significant that so little M406 was found there. Your M406 subgroup is most common in the eastern Mediterranean. The Lezgians live in Azerbaijan and Russian Dagestan -- areas that comprise the eastern end of the Caucasus. But there was really no M406 among the Lezgians' neighbors within this eastern area. For more information on the Lezgians, link to
We do not know if the Lezgins might belong to your specific G2a3a3a subgroup.
The reason your subgroup was renamed in the last few months is due to the discovery of a large, brand-new G2a3a subgroup characterized by sharing the L645 mutation. This mutation was discovered in a man having testing in the Walk through the Y Project a few months back. We now have five men fully confirmed at belonging to the L645 (G2a3a2) subgroup. It is likely that all members of your G2a3a3a subgroup are not positive for L645. Mr. Der-Tavitian from within G2a3a3 tested for L645 and was found negative.
You are very fortunate to belong to a subgroup which is defined by an odd values for DYS454 and DYS459a and almost all of you have tested for this. And likewise we know your status as regards those who belong to additional subgroups of your subgroup. If additional persons are added to your subgroup, we will be looking for ways to subdivide you further. But there is no additional testing we can recommend this year to better define your group.
By way of exception to these comments, if Mr. Oddo would confirm his membership in this group by testing just for DYS454 and DYS459.  The cost of this is about $15.
