News for G2a3a5 persons
Because no researcher has yet tested specifically for your G2a3a5 subgroup in their study, we have to confine the news to the more general G2a3a group.
We are also hampered in reporting news specific even 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 G2a3a5 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.
Because you lack one of the marker values found in L645 men, I suppose you G2a3a5 men who share the DYS436 marker value oddity are not within L645. And this seems nearly fully confirmed because Mr. Bolinage within your subgroup was specifically found negative for L645.
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.
