RT Journal Article T1 Indian Signatures in the Westernmost Edge of the European Romani Diaspora: New Insight from Mitogenomes A1 Gómez Carballa, Alberto A1 Pardo Seco, Jacobo José A1 Fachal Vilar, Laura A1 Vega Gliemmo, Ana Paula A1 Cebey López, Miriam A1 Martinón Torres, Nazareth A1 Martinón Torres, Federico A1 Salas Ellacuriaga, Antonio AB In agreement with historical documentation, several genetic studies have revealed ancestral links between the EuropeanRomani and India. The entire mitochondrial DNA (mtDNA) of 27 Spanish Romani was sequenced in order to shed furtherlight on the origins of this population. The data were analyzed together with a large published dataset (mainlyhypervariable region I [HVS-I] haplotypes) of Romani (N = 1,353) and non-Romani worldwide populations (N.150,000).Analysis of mitogenomes allowed the characterization of various Romani-specific clades. M5a1b1a1 is the most distinctiveEuropean Romani haplogroup; it is present in all Romani groups at variable frequencies (with only sporadic findings in nonRomani) and represents 18% of their mtDNA pool. Its phylogeographic features indicate that M5a1b1a1 originated 1.5thousand years ago (kya; 95% CI: 1.3–1.8) in a proto-Romani population living in Northwest India. U3 represents the mostcharacteristic Romani haplogroup of European/Near Eastern origin (12.4%); it appears at dissimilar frequencies across thecontinent (Iberia: ,31%; Eastern/Central Europe: ,13%). All U3 mitogenomes of our Iberian Romani sample fall within anew sub-clade, U3b1c, which can be dated to 0.5 kya (95% CI: 0.3–0.7); therefore, signaling a lower bound for the founderevent that followed admixture in Europe/Near East. Other minor European/Near Eastern haplogroups (e.g. H24, H88a) werealso assimilated into the Romani by introgression with neighboring populations during their diaspora into Europe; yet someshow a differentiation from the phylogenetically closest non-Romani counterpart. The phylogeny of Romani mitogenomesshows clear signatures of low effective population sizes and founder effects. Overall, these results are in good agreementwith historical documentation, suggesting that cultural identity and relative isolation have allowed the Romani to preserve adistinctive mtDNA heritage, with some features linking them unequivocally to their ancestral Indian homeland.
