Paternal Lineage Analysis Supports an Armenian Rather Than a Central Asian Genetic Origin of the Hamshenis
Ashot Margaryan et al
Hum Biol. 2012 Aug;84(4):405-22

The Hamshenis are an isolated geographic group of Armenians with a strongethnic identity who, until the early decades of the twentieth century, inhabited thePontus area on the southern coast of the Black Sea. Scholars hold alternative views ontheir origin, proposing eastern Armenia, western Armenia and Central Asia,respectively, as their most likely homeland. To ascertain whether genetic data from thenon-recombining portion of the Y chromosome is supportive any of these suggestions,we screened 82 Armenian males of the Hamsheni descent for 12 biallelic and 6microsatellite Y-chromosomal markers. These data were compared with thecorresponding datasets from the representative populations of the three candidateregions. Genetic difference between the Hamshenis and other groups is significant and backs up the hypothesis of the Armenian origin of the Hamshenis, indicating the centralhistorical Armenia as a homeland of the ancestral population. This inference is further strengthened by the results of admixture analysis, which does not support the CentralAsian hypothesis of the Hamshenis origin. Genetic diversity values and patterns of genetic distances suggest a high degree of genetic isolation of the Hamshenis consistentwith their retention of a distinct and ancient dialect of the Armenian language

Mini-haplotypes with only 6 markers(table4) Hamshen (82), SWA (96), CA (145), Syunik (296) and Uzbek (39)
DYS19, DYS388, DYS390, DYS391, DYS392,and DYS393

The 12 UEP markers typed for all samples identified nine haplogroups whenconsidering all data sets and seven haplogroups in the Hamshenis only (Table 1).Themost frequent (i.e. modal) haplogroup in the Hamshen is BT*(xDE,JK) with a requency of about 44%, which is two- to four-fold higher than in comparative datasets. In south-western Armenian and central Armenian groups the modal haplogroup is J, which is also highly represented in the Hamshen (31.7%) and Syunik (37.17%)groups, whereas in the Uzbeks it has a frequency of only about 7.7%. The P*(xR1a) isthe most frequently encountered haplogroup in the Syunik and Uzbek groups whilehaving only about 8.5% frequency in the Hamshenis. According to the exact test valuesat the haplogroup level all the populations studied significantly differ from each other (p<0.05).The six microsatellites define a total of 231 compound UEP+microsatellitehaplotypes the most frequent of which are shown in Table 2. The Hamshenis share their “modal haplotype” (15.9%) only with the group of central historical Armenia (CA)(2.8%), while it is completely absent in other groups. The modal haplotypes of the threeArmenian groups of Syunik, SWA and CA are shared at various degrees among them but not detected in the Hamshen and Uzbek populations. The most frequent haplotypeof the Uzbeks is present at negligible levels in Hamshen, Syunik, and SWA.

According to the 6 microsatellite data, the modal haplogroup BT*(xDE,JK) inthe Hamshenis is most likely to be the haplogroup G based on the results of higher resolution Y-chromosomal typing (Cinnioğlu et al. 2004; Rootsi et al. 2012). TheHamshenis modal haplotype seems to be a quite unique one, as it was encountered onlyin 2 samples from Turkey (Cinnioğlu et al. 2004, with a frequency of 0.44%) and 2Armenian samples (Rootsi et al 2012, with a frequency of 0.47%) all the four belongingto the haplogroup G1a. This haplotype is completely absent in any of Caucasian(Balanovsky et al. 2011; Nasidze et al. 2003; Bertoncini et al. 2012), Near-Eastern (El-Sibai et al. 2009) and other Armenian (Herrera et al. 2012) populations. It is quiteinteresting to note, that the two samples from Turkey bearing Hamsheni modalhaplotypes were collected in the “region 3” (Cinnioğlu et al. 2004), which coincideswith the Hamshenis homeland area near the city of Trabzon. High frequency rate (about16%) of this “unique” haplotype in the Hamsheni population and its virtual absence inthe Near-East and Caucasus, along with the overall low genetic diversity of Hamshenis,may indicate a well expressed founder effect in this specific Armenian subpopulation.

Many thanks for the paper.

My theory of the Italian Refugium of hg. R, at least from R-L51 and subclades, by its derivation from Z2113, is probably demonstrated.
