News for general G2a3b1a3 persons
There is considerable good news for our G2a3b1a3 subgroup. For about 5 years we have been calling it the DYS568=9 subgroup. DYS568 is found in upgrades to 67 markers or by ordering just DYS568. All attempts to find a more reliable SNP mutation (instead of DYS568) to define our subgroup have failed over the past five years. But we have now found a man in our group in the 1000 Genomes Project, and he has several dozen SNPs never previously identified. We have been able to get two of these made into individual tests. There is enough preliminary evidence to confirm that these SNPs are valid and found in DYS568=9 men. We suspect that Z724 will be an overall SNP that contains within it the DYS568=9 group and some other miscellaneous smaller groups. A haplogroup G man from Beijing China tested positive for Z724 and this gives a hint that Z724 has the widest coverage. Then under Z724 is Z1903 which may be equivalent to DYS568=9, but we are still trying to determine its boundaries. We may need more of you to test for these two SNPs to define their boundaries.
It is necessary to backtrack just a bit. In my own sample, the lab by chance noticed a SNP mutation they have labeled L640. Testing done in recent months established that this is confined to a small number of British Isles ancestry DYS568=9 men. Amazingly the man in the 1000 Genomes Project from Utah also has this mutation. So he is somewhat of a cousin to me. But the testing for Z1903 shows that Z1903 includes not only our British L640 group but also DSY568=9 men outside it.
And all those other SNPs found in the Utah man in the 1000 Genomes Project likely contain among them some that define the branching within DYS568=9. We eventually may learn from this exactly when the Jewish and other defined subgroups branched off providing thereby critical information on the migrations of our ancestors.
I reported to you early last year that two DYS568=9 men were found in North Ossetia, in the central part of the Caucasus Mountains. These were the first DYS568=9 men identified outside Europe. There have since been no other such men identified though we have received additional G samples from the Caucasus region. In late January 2012 there was a study from the Caucasus that for the first time included values for the YCA marker. This is rather critical for us because we almost all have 20, 21 for this, and that is atypical when compared to other men within the G2a3b1a (L140) group. This study I mentioned only involved the Tats of the n.e. Caucasus (a region the Russians call Dagestan) There was one 20, 21 G man listed, but I determined on the basis of the other marker values that he is unlikely to be DYS568=9. Hopefully more studies will list results for YCA.
We did add some new European DYS568=9 men to the project this past year.
I have listed three categories of general DYS568=9 men such as yourself:
(1) Confirmed DYS568=9 and negative for all DYS568=9 subgroups
(2) Confirmed DYS568=9 men who have not tested for all subgroups
(3) Those only predicted DYS568=9.
For those listed as tested for everything, this is as far as we can presently go for you. We will continue to look at other possible ways to further subdivide you.
For those listed as confirmed DYS568=9 but not completely tested, the picture is a bit complex. The great bulk of you are listed there because you have not tested for the L640 SNP. However, we know who is in this L640 group and who is not. As of this writing, only Mr. Biichle needs to test for subgroups, and we probably can narrow the problem to one or two markers which only cost $7.20 each.
For those only predicted DYS568=9, we would like to really encourage testing for the DYS568 marker. It only costs $7.20 -- what a bargain! Results for DYS568 also can be obtained by upgrading to 67 markers, which is fine, but it is but more expensive using that route.
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. email@example.com.
