“…Furthermore, the small numbers and different sets of Y-STRs used in some studies, the insufficient and variable phylogenetic resolution, and the local character of the studies have prevented the reconstruction of a clear general picture. 4,22,[28][29][30] Moreover, studies that used a large number of markers were forced to reduce the phylogenetic resolution in order to compare with previous data. 21 In addition to these limitations, the information of the Roma volunteers has been restricted to their geography tracks (ie, country of the sampling) ignoring the Roma group affiliation, which might have masked their complex population history.…”

Origins, admixture and founder lineages in European Roma

The Roma, also known as 'Gypsies', represent the largest and the most widespread ethnic minority of Europe. There is increasing evidence, based on linguistic, anthropological and genetic data, to suggest that they originated from the Indian subcontinent, with subsequent bottlenecks and undetermined gene flow from/to hosting populations during their diaspora. Further support comes from the presence of Indian uniparentally inherited lineages, such as mitochondrial DNA M and Y-chromosome H haplogroups, in a significant number of Roma individuals. However, the limited resolution of most genetic studies so far, together with the restriction of the samples used, have prevented the detection of other non-Indian founder lineages that might have been present in the proto-Roma population. We performed a high-resolution study of the uniparental genomes of 753 Roma and 984 non-Roma hosting European individuals. Roma groups show lower genetic diversity and high heterogeneity compared with non-Roma samples as a result of lower effective population size and extensive drift, consistent with a series of bottlenecks during their diaspora. We found a set of founder lineages, present in the Roma and virtually absent in the non-Roma, for the maternal (H7, J1b3, J1c1, M18, M35b, M5a1, U3, and X2d) and paternal (I-P259, J-M92, and J-M67) genomes. This lineage classification allows us to identify extensive gene flow from non-Roma to Roma groups, whereas the opposite pattern, although not negligible, is substantially lower (up to 6.3%). Finally, the exact haplotype matching analysis of both uniparental lineages consistently points to a Northwestern origin of the proto-Roma population within the Indian subcontinent.

“…Of all the populations examined in this study (see Supplementary Table S1 for articles [24][25][26][27][28][29][30][31][32][33][34][35][36][37][38] citing the reference populations), Ladakh, Southern Iran and Pakistan, exhibit the highest Y-chromosome diversity. Interesting, these three populations lie in a region of genetic confluence geographically located in west-central Asia.…”

Ladakh, India: the land of high passes and genetic heterogeneity reveals a confluence of migrations

Owing to its geographic location near the longitudinal center of Asia, Ladakh, the land of high passes, has witnessed numerous demographic movements during the past millenniums of occupation. In an effort to view Ladakh's multicultural history from a paternal genetic perspective, we performed a high-resolution Y-chromosomal survey of Ladakh, within the context of Y haplogroup and haplotype distributions of 41 Asian reference populations. The results of this investigation highlight the rich ethnic and genetic diversity of Ladkah which includes genetic contributions from disparate regions of the continent including, West, East, South and Central Asia. The phylogenetic signals from Ladakh are consistent with the Indo-Aryans' occupation during the Neolithic age and its historic connection with Tibet, as well as the East-West gene flow associated with the Silk Road.

“…Previous studies (Gresham et al 2001;Zaharova et al 2001;Ploski et al 2002;Nagy et al 2007; Füredi et al 1999; Peričić et al 2005a;Kalaydjieva et al 2001a) already had assessed Y-STR diversity in other Roma groups (see Table 1) using, however, very distinct sets of loci. Only seven Y-STRs were common to all studies, namely DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393.…”

SummaryThe European Gypsies, commonly referred to as Roma, are represented by a vast number of groups spread across many countries. Although sharing a common origin, the Gypsy groups are highly heterogeneous as a consequence of genetic drift and different levels of admixture with surrounding populations. With this study we aimed at contributing to the knowledge of the Roma history by studying 17 Y-STR and 34 Y-SNP loci in a sample of 126 Portuguese Gypsies. Distinct genetic hallmarks of their past and migration route were detected, namely: an ancestral component, shared by all Roma groups, that reflects their origin in India (H1a-M82; ∼ 17%); an influence from their long permanence in the Balkans/Middle-East region (J2a1b-M67, J2a1b1-M92, I-M170, Q-M242; ∼ 31%); traces of contacts with European populations preceding the entrance in the Iberian Peninsula (R1b1c-M269, J2b1a-M241; ∼ 10%); and a high proportion of admixture with the non-Gypsy population from Iberia (R1b1c-M269, R1-M173/del.M269, J2a-M410, I1b1b-M26, E3b1b-M81; ∼ 37%). Among the Portuguese Gypsies the proportion of introgression from host populations is higher than observed in other groups, a fact which is somewhat unexpected since the arrival of the Roma to Portugal is documented to be more recent than in Central or East Europe.
