                                                                             G2a3a2 group

This group was only recently identified so little is known of it.

The M406 mutation that characterizes the broader group of G2a3a persons is found in about 5%
of the population of Turkey. Likely this is the country with the most men with the M406 mutation. Yet we
have only a few detailed samples from Turkey. That Turkey has the most G2a3a persons does not
mean that this country is where the ancient ancestor who developed this mutation once lived, but it raises
suspicion that many of those today in other parts of the world once had an ancestor who once lived in
today's Turkey.

For information on what is known of the origins of the G2a3a grouping and migrations and time
relationships to other G groupings link to the migration-time page.

Persons who are G2a3a2 are confirmed as such by special SNP testing. Persons who are G will all be
positive for the M201 SNP. In addition, those positive for P287 are G2, and those also positive for P15 are G2a.
The P287 SNP is a rather recently identified SNP, and most of our samples were not tested for it. However,
anyone who is P15+ will necessarily be P287+.   There are two further tests to bring the subcategorization
down to G2a3a. First, the men here will be positive for U8 or S126 or L30 (G2a3). Only a few men have been found
positive for this because it just recently became available in commercial labs. Finally, the men here will be
M406+. This is the SNP specific for G2a3a. Anyone who is M406+ will necessarily be positive for all the
other SNPs mentioned above. Finally, all the men here will be positive for two additional SNPs, L184 and
L185 (G2a3a2)

Recommended additional deep ancestry testing for men here with the interest and funds for this:

Because there is such a diversity of samples within the M406+ group, upgrades to Family Tree DNA's 67
markers are always very useful in determining proper relationships and for time calculations to common ancestors.
For deep ancestry purposes, only one person within a surname project needs the full 67 markers. Additional testing
within surname projects might be indicated for more recent comparisons.

At Family Tree DNA for those tested there, in the haplotree section of a G2a3a person's results page is listed
also a deep clade SNP test to order.  This contains the M406 mutation what characterizes G2a3a.

The L184 and L185 SNPs are new and not yet available as part of the deep clade test. We currently cannot predict
who will or will not be positive for these two SNPs   When they are available for testing, it is expected that
they will first be added to the Order Tests section on the Family Tree results page. They will then be found in
the Advanced Orders section as SNP tests for $29US each.
