News for G2a3a1 persons
Because no researcher has yet tested specifically for your G2a3a1 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 G2a3a1 subgroup.
Within the project, there was a major development last year with the identification of the L645 SNP. This became the identifier for a new, major subgroup of G2a3a, and lots of samples were moved to this category.   So many of the G2a3a persons either belong to your subgroup or to the new L645 subgroup.
We have divided your G2a3a1 subgroup into three sections:
(1) Those who are confirmed L14 and are negative for L90 as well
(2) Those who are confimed L14 and have never tested for L90
(3) Those only predicted L14.
With regard to persons (1) and (2) this involves whether one is tested for L90 or not.  We had enough testing of L90 that it is now considered to have the same coverage at L14.  However, this is really not 100% certain, and there may exist a subgroup of L14+ L90- persons.   True, such a subgroup will be small, but it may exist.  So any additional persons who test for L90 are appreciated.  Only four men in the roster tested for L90.
For those of you in the predicted L14 category, additional testing for L14 ($29 US) would be very helpful.  Those who are predicted L14 have many of the features in their marker values of L14 men, but their L14 status is not 100% certain.  Special mention must be made for those who belong to a surname group with multiple members, such as May/Mayes/Mays, because only one person in this surname group needs to test because L14 is much older than your group and all those in the surname grouping will have the same results for L14.  In addition, the men with the Levonian and Posey surnames  have a representative who has already done testing for your surname group.
As mentioned in the general news section, if you are willing to better define your grouping, I will be glad to give individual recommendations and help. rayhbanks@cox.net.
