News for general G1 persons.
G1 today seems most common in Iran and the countries bordering it to the west. But G1 has spread out as far east as India, Siberia and China and west to western Europe. Late last year we learned from a study that there is pocket of G1 persons in Armenia, similar to the G1 pocket of men found earlier in Kazakhstan. We only have limited information about these Armenian samples, but the Kazakh men have been in the G project and well tested. New studies also showed that G1 is otherwise rare in the Caucasus Mountains area north of Armenia.
Your sample in the G project has provided valuable information. It is only by seeing as many samples as possible that new subgroups can be identified.
There are three types of general G1 persons
(1) Those only predicted G1. Typically you only tested a few markers -- making prediction difficult. But you have 12 at marker DYS392 which is common only among G1 persons.
(2) Those confirmed G1 but not tested for all the subgroups
(3) A small number of persons confirmed G1 who have been found negative for all the known G1 subgroups.
The general news for general G1 persons this year is the shrinkage of your group due to the adding of a new, large subgroup within G1 designated for now as G1c. This is a very interesting new subgroup that consists so far both of Jewish men from n.e. Europe and Muslim men from the Middle East. This combination suggests G1c may have arisen in the Middle East before either of those religions existed.
Those of you who tested negative for the older G1 subgroups (G1a and G1b) may belong to this new G1c subgroup. The boundaries are not clear. And those not tested for any G1 subgroups might belong to any of them or none of them. Even if negative for the three known subgroups, that in itself is important information and you form your own distinctive group which likely has a SNP mutation that defines it but yet to be found..
Those who are only predicted G1 really need to have what Family Tree DNA calls the deep clade test that automatically checks for G1, G1a and its subgroups and for G1b. If you prove not to be G1, then this test will greatly clarify where you are in the G tree.
And for those who have been found G1 and negative for all subgroups, it is worthwhile making sure you have been tested for all three G1 SNPs. These are listed as equivalent SNPs in the few who tested for them, but they may not be. There could be varying results for these (M285, M342 and new this year L833), and such varying results would be the basis of a new subgroup.
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.
