News for G1a3 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 (your subgroup). We only have limited information about these Armenian samples, but you 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 have a very fortunate subgroup.  The mutations that define your subgroup, are all found within the first 12 markers, which everyone has tested.  This means we already know exactly which subgroup it is to which each of you belong.  So we cannot recommend any additional SNP testing this year for you.  If more persons are added to your subgroup, we will be looking for additional subgroups within G1a3 that could identify branching within your subgroup.
