News for G1a2 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.
You are somewhat fortunate in that we cannot recommend any additional testing for you this year. The unusual mutation that defines your subgroup is found within the first 12 markers, for which every project member has tested. If the size of your subgroup increases, we will be alert for some additional mutation that might define a G1a2 subgroup.
