Haplogroup G-M406

Perhaps about 5% of men in Turkey are G-M406, the highest percentage of the general population in any country yet sampled. This 5% figure is based on the finding of the value of 21 at STR marker DYS390 in 21 of 57 G samples from throughout Turkey. Among G persons, the 21 value is seen overwhelmingly in G-M406 persons. But values other than 21 occur to a small extent in G-M406 persons. So the total G-M406 percentage within Turkish G is likely close to 50 percent, and the 57 SNP-confirmed G samples represent 11% of 523 Turkish samples obtained in the largest study yet conducted of Turkish population genetics.[14]

In adjacent Greece, SNP testing determined that half of eight G samples were G-M406. The G samples represented 5% of 171 Greek samples. In contrast in nearby Crete, G-M406 was only 20% of the 21 G samples, with G samples representing 11% of 193 island samples.[1] Though treated separately in this study, Crete is part of Greece but with a different settlement history. Farther out in the Mediterranean, in a smaller sample size from Cyprus 4 of 7 G samples have the distinctive 21 value seen overwhelmingly in G-M406 persons.[15]

Just to the south of Turkey among the Kurds of Iraq 7 of 14 likely G STR samples in the YHRD database have the value of 21 at DYS390 suggesting half the G population there belongs to G-M406.[16] This relatively high percentage of G-M406 is confined to the country's northern Kurdish region.

Lebanon, Jordan and Palestine also have significant G-M406 populations though small sample sizes make broad conclusions difficult. In one study, 4 of 5 Palestinian G samples have the distinctive DYS390=21 value.[17] In Lebanon, at least 10 of 37 G samples have G-M406 features and are found among all the major religions there.[18] In Jordan, 7 of 15 available G samples have 21 at marker DYS390.[15] None of the G samples among the Druze peoples in these locations have STR marker values typical of G-M406 persons according to recent studies.[19] However, recent testing on Family TreeDNA points to some families whose origins lie in Palestine/Israel, but who have moved to Lebanon or Syria prior to the 1500-1700 period who happen to be carrying around 50-60% of the Druze among the Haplogroup G population in Druze. There is initially reasonable assurance the samples are within the DYS459=8 subgroup (that is also negative for its own DYS392=12 subgroup). Overall, these sets of related subgroups make up a major part of G-M406 men and are negative for the L14 and L645 SNP-defined subgroups. The sample has a few marker values that are a little different and the Druze samples have 22 at DYS390 compared to the more typical 21 in the majority of G-M406 samples. So this is good indirect evidence that at least half of the G among the Druze is G-M406. In Syria, G-M406 seems less common than in the countries closer to the Mediterranean. Only 3 of 17 G samples there have the 21 value discussed.[15]

G-M406 and its subclades G-PF3293, G-M3302 and G-L14 were found in the Hui_People of China by 23mofang lab, totaling 0.66% of Hui people samples analyzed.[20]

Of note regarding G-M3302 among the Hui is that all 5 testers actually belong to a much deeper subclade found only (for now) in Shangdong Province. The actual clade is G-M3302>M3422>M3240>M3336>FT203871>FT27194>MF344148. The split at FT27194 occurred about 500 BC as estimated by TheYTree. [21]

The largest source of G STR samples from Iran is the YHRD database where only 1 of 340 Iranian samples has a value of 21 for DYS390 together with the other marker values consistent with G-M406 samples.[16] It is possible G-M406 persons in Iran have different STR marker values. The countries that share the Persian Gulf and Gulf of Oman with Iran were the subject of a separate small study which provided STR samples with G patterns similar to those in Iran. But the percentage of G-M406 (based on the 21 value) would seem higher than in Iran in Dubai with half of 6 G samples with 21. None of the three G samples from Yemen and Saudi Arabia had this DYS390 value.[22]

In the Nasidze study[23] of the Caucasus Mountains area, his 87 likely G STR samples now in the YHRD database have only 8 samples with the distinctive DYS390 value of 21 that is the overwhelming feature of the G-M406 group. Only in Georgia where 3 of 16 likely G samples have 21 does G-M406 apparently have a significant presence.[16]

The Haplogroup G Project newsletter[24] is gradually summarizing the percentage of G-M406 men in other areas based on the likely or proven G-M406 samples in the project's large project G database.[25] This source has more reliability in identifying the totality of G-M406 samples because it does not rely on the value at STR marker DYS390 as the sole criterion.

The newsletter indicates (in descending order) in Italy 20% of 156 G samples......Spain 15% of 56 G samples.....Netherlands 15% of 20 G samples......Switzerland 8% of 51 G samples.....Iran 6% of 34 G samples....Poland 4% of 75 G samples......France 4% of 46 G samples......Ireland 3% of 29 G samples.......India 3% of 18 G samples.

In addition, a research study which provided Indian and Pakistani STR marker samples did not find that any of the 20 G samples from various groups contained the DYS390=21 value so typical of G-M406.[26] And a study of Sardinia found 7% of 51 G STR samples had the characteristic 21 value.[27] Possibly of significance, half of these "21" samples were found in the asylum land of the ancient Sardinian population in the isolated central highlands which has no evidence of occupation by external colonial powers beginning with the Phoenician period.[28] In the Spanish islands to the west of Sardinia, in another study none of 7 G STR samples from Ibiza are G-M406, but 2 of 4 G samples in Majorca have the DSY390 value of 21. This same study found one 21 value among 25 G Sephardic Jews whose history is intertwined with Spain.[29] Of the 291 STR samples of all types in the YHRD database[16] from Egypt none of the DYS390=21 samples has the same features of known G-M406 samples from other areas of the Mediterranean.

Estimated Age : 7800 YBP [31] Descendant branches: G-L645, G-Z17886

G2a2b1a1b2a is characterized by possessing the SNP mutation designated as L645. G2a2b1a1b2a persons so far all have the value of 9 at STR marker DYS578. Both European and Near Eastern members of this subgroup have been identified. L645 was first identified at Family Tree DNA in summer 2011. It was found at chromosome position 2948673 and represents a mutation from A to C.

Inside Z17887 there is a cluster of G-M406 men who have the unusual (for G-M406 men) value of 14 at STR marker DYS436 instead of the ancestral 12 value This is so far a relatively small cluster with ancestral histories confined to Galicia and Basque country in Spain and to various parts of Portugal. Too few samples are available to estimate with some reliability when the common male ancestor of this cluster may have lived.. NB : According to familytree DNA M406 collaborative project at least 10 samples have the value of 14 at DYS436 and are not identified as Basque, Portuguese nor Galician

Estimated Age : 7800 YBP [32] Descendant branches: G-Z17084, G-Z45043

G2a2b1a1a is characterized by possessing the SNP mutation designated either as L14 or S130. G2a2b1a1a persons typically have DYF395S1 values of 16,16 and a DYS565 value of 11.

L14 and S130 are different designations for the same SNP mutation. The L14 version was developed at Family Tree DNA, and S130 was developed at Ethnoancestry. But this mutation was first identified at the University of Central Florida in 2006 as U16 and well before the associated researchers published a formal description in 2009 of its location at 21327383 on the Y chromosome, reference number rs35474563. The mutation involves a C to T change.[33]

Another SNP of interest is S133 which was first identified in 2008 at Ethnoancestry in London, England in a G-M406 person, but it is also available as L90 elsewhere. Its location on the Y chromosome is given as 20087688, reference number rs35169834. The mutation is a change from G to A. In the several persons in which this mutation have been found it does not form a separate category from G2a2b1a1a because the tested persons also had the mutation that defines G2a2b1a1a (L14 or S130). It is possible there are persons who are positive (derived) for either L14/S130 while negative (ancestral) for L90/S133, and such a situation would necessitate creating a separate G-M406 category.

S9350 (renamed G-Z41194 by yfull.com [34]) formed 8000 YBP was first identified in 2013. Its location on the Y chromosome is given as 6834584, reference number rs953306008.[35] The oldest G-S9350 sample known lived in Kaman Kalehöyük, Kırşehir Province in Turkey around 3650 year ago. This was from an ancient Assyrian trading post. According to https://www.yfull.com/tree/G-Z41194/ none of the samples 13 tested positive to date are Turkish, Greek or Italian and this branch is the only M406 branch with Europeans that are not Armenian or Turkish in origin, but the eldest branch line appears to be Lebanese. A further 21 samples at FamilyTreeDNA support this. Sample testing of 50 samples at June 2023 (many do not pay to have public disclosure) across sites have so far shown samples in Iran, Azeris, Palestinian, and Lebanon, all places of ancient Assyrian control. In addition a sub branch exists via Austria, England, Spain and Belgium. This sub branch may have been dispersed via Norman conquest given research. According to familytree DNA M406 Collaborative project, 3 patrilineal descendants of Giorgi Saakadze are from G-Y24444, a subclade of G-S9350 [36]

Estimated Age : 7800 YBP [37] Descendant branch(s): G-BY21756, G-M3422 M3302 was first identified by Underhill et al . Its location on the Y chromosome is given as 12992361, reference number rs576974702.[38]

Estimated Age : 8700 YBP [39] Descendant branch: G-PF3296

There is a cluster of G-M406 men belonging to the G2a2b1b - PF3293 subgroup who (1) have the unusual (for G-M406 men) value of 12 at STR marker DYS454 instead of the ancestral 11 value (2) and have a relatively close genetic distance when 67 markers are compared. The shared common ancestor may have lived about 2,000 years ago or so. This DYS454 STR marker is not as reliable as a SNP mutation for categorizing men, but the 12 value plus other uncommon features and the close genetic distance make is certain this a distinct subgroup. A few persons who belong to this cluster may have had more recent ancestors who mutated to a value other than 12, but such samples have not surfaced.

Many men in this cluster have developed one or two other mutations at STR markers which make the cluster even easier to identify. The largest number of cluster men have a mutation at DYS459a from the ancestral 9 to 8. And many have a mutation from the ancestral 11 to 12 at DYS392. The DYS392=12 value is seen almost exclusively in G1 persons, with this G-M406 cluster being a major exception.

This cluster seems overwhelmingly made up of three identifiable ethnic groups (a) Ashkenazi Jews based on distinctive surnames together with ancestral origins in northeastern Europe south of Scandinavia, (b) Conversos with Hispanic surnames and (c) Men with Italian ancestral origins. However, an available sample from Iran also likely belongs to this cluster. The Ashkenazi Jews are so far not found in the group with the ancestral 11 at DYS392. And the Hispanics are so far not found within the DYS392=12 group. (See also page covering Jews with Haplogroup G (Y-DNA)). This cluster seems to be determined by the SNP FGC41427 or his subgroup S11415, according to Family Tree DNA haplotree [40] (SNP S9591 has been chosen by Yfull for this branch)

Theres is another cluster of G-M406 > G-PF3296 men bearing the G-Y32612 Mutation. The G-Y32612 Mutation arhose around 7200 YBP, but the TMRCA of all G-Y32612 bearer is estimated only 900 YBP.[41] Members of this cluster are found in Yemen (Hadramut), Oman (Zufar), Indonesia, Malaysia and Saudi Arabia (Makkah), many members of this cluster are part of the Ba 'Alawi sada, This cluster has spread to Indonesia, G-PF3296 is a common haplogroup inside the Arab Indonesians community especially among descents of Sayyid Hadhrami.

The men in this cluster of G-M406 have (1) the unusual (for G-M406 men) value of 10 at STR marker DYS459b instead of the ancestral 9 value (2) and have a relatively close genetic distance when 67 markers are compared. This is so far a relatively small cluster with French and British ancestral histories. Too few samples are available to estimate with some reliability when the common male ancestor of this cluster may have lived.
