News for G1a5 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 very fortunate to be part of a subgroup whose defining mutations are found within the first 12 markers. Everyone tests for these. So this year we cannot recommend any additional testing for subgroups for you. If additional samples are added to the G1a5 subgroup, we will be looking for additional mutations within your subgroup that would show ancestral splitting.
