News for G2a3a2 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 G2a3a2 subgroup.
But perhaps the really big news for you -- or perhaps a surprise -- is that you are now listed in a brand-new 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.  Based on their results, I was able to predict a number of men who are likely to also have this mutation.  The biggest predictor is having a value of 9 at the DYS578 marker.  A number of M406 men have not tested for DYS578 because it is found only when upgrading to 67 markers.  So there are likely more L645 men than I can predict presently.
L645 is a major new group, and I think at least a third of M406 men belong to your subgroup.  The data so far indicate this is somewhat common about Armenians in Turkey and it may be spread out far into Europe and elsewhere.  This is the first time in about five years we have been able to divide up the M406 group additionally.
We have divided your G2a3a2 subgroup into two sections:
(1) Those who are confirmed L645
(2) Those who are only predicted L645
For those who are confirmed L645, there are no more tests that we can recommend for you to determine further subgrouping.  However, we will continue to look for ways to further subdivide your subgroup as more persons are confirmed L645.
For those of you only predicted L645, additional confirmation of your status ($29) will be extremely useful.  There are a few of you so close in your marker values to tested persons, that L645 testing is not essential.  I can discuss this individually.
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.
