News for G1a4a persons.
Before getting to your specific G1 subgroup, G1 in general 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 also 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. It is unknown if the new Armenian samples might fall within G1a or not.
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 two types of G1a4a men.
(1) Those confirmed as having one of the defining values of 8 at marker DYS459a.
(2) Those only predicted to have this value.
If you are only predicted DYS459a=8 your other marker values strongly suggest you are part of this subgroup, but full confirmation is recommended by ordering DYS459. It is quite inexpensive.
I would also be more comfortable in your designation as a subgroup of G1a4 if the men in your subgroup would also test for DYS494 as well. DYS494=8 is the defining mutation of G1a4. It also is very inexpensive to test.
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. firstname.lastname@example.org.
