The identification of a growing number of novel Mendelian disorders and private mutations in the Roma (Gypsies) points to their unique genetic heritage. Linguistic evidence suggests that they are of diverse Indian origins. Their social structure within Europe resembles that of the jatis of India, where the endogamous group, often defined by profession, is the primary unit. Genetic studies have reported dramatic differences in the frequencies of mutations and neutral polymorphisms in different… Expand
Mutation history of the roma/gypsies.
TLDR
The existence of multiple sub isolates, with endogamy maintained to the present day, suggests a general approach to complex disorders in which initial gene mapping could be performed in large families from a single Gypsy group, whereas fine mapping would rely on the informed sampling of the divergent subisolates and searching for the shared genomic region that displays the strongest linkage disequilibrium with the disease.

Origins, admixture and founder lineages in European Roma
TLDR
The exact haplotype matching analysis of both uniparental lineages consistently points to a Northwestern origin of the proto-Roma population within the Indian subcontinent. Expand
Genetic structure of the paternal lineage of the Roma people.
TLDR
An analysis of Y-chromosomal markers from five Roma and two non-Roma populations is provided to investigate the genetic relatedness of the Roma population groups to one another, and to gain further understanding of their likely Indian origins, the genetic contribution of non-roma males to the Roma populations, and the early history of their splits and migrations in Europe. Expand
Y-haplogroup frequencies in the Slovak Romany population
European 'gypsies', commonly referred to as Romanies, are represented by a large number of groups spread across many countries. We performed a population genetic study on 200 unrelated Romany malesExpand
Reconstructing the Indian Origin and Dispersal of the European Roma: A Maternal Genetic Perspective
TLDR
The results show that the maternal lineage composition in the Roma groups follows a pattern of different migration routes, with several founder effects, and low effective population sizes along their dispersal. Expand
Refining the genetic portrait of Portuguese Roma through X-chromosomal markers.
TLDR
Evidence is provided that a sex-biased admixture with Europeans is probably associated with the founding of the Portuguese Gypsies, underlining the importance of using combined information from the X chromosome and autosomes to dissect patterns of genetic diversity. Expand
Divergent patrilineal signals in three Roma populations.
TLDR
Y-chromosome distributions in three Roma collections residing in Belgrade, Vojvodina and Kosovo are reported for the first time and illustrate that the most notable difference among the three Roma populations is in their opposing distributions of haplogroups H and E. Expand
Analysis of the mitochondrial CYTB gene sequence in human populations of northeastern Bosnia
TLDR
The results of this study indicate the region of CYTB gene can be a benefit in providing some additional information in the analysis of genetic structure of human populations and can be additionally applied in population studies. Expand
A genetic historical sketch of European Gypsies: The perspective from autosomal markers.
TLDR
Analysis of genetic distances revealed that the average level of genetic differentiation between Gypsy groups was much larger than that observed between the corresponding non-Gypsy populations, and the high rate of heterogeneity among Gypsies can be explained by strong genetic drift and limited intergroup gene flow. Expand
The Phylogeography of Y-Chromosome Haplogroup H1a1a-M82 Reveals the Likely Indian Origin of the European Romani Populations
TLDR
The phylogeographical patterns and diversity estimates indicate an early origin of this Y-chromosomal haplogroup H1a1a-M82 in the Indian subcontinent and its further expansion to other regions. Expand

Patterns of inter- and intra-group genetic diversity in the Vlax Roma as revealed by Y chromosome and mitochondrial DNA lineages
TLDR
The study unambiguously points to the common origins of the three Vlax groups and the recent nature of the population fissions, and provides preliminary evidence of limited genetic diversity in this young founder population. Expand
Dual origins of Finns revealed by Y chromosome haplotype variation.
TLDR
Genetic evidence for the dual origins of Finns is presented by evaluating the pattern of Y chromosome variation in 280 unrelated males from nine Finnish provinces and revealing two major star-shaped clusters of Y haplotypes, indicative of a population expansion from two common Y chromosomes. Expand
Y chromosomal DNA variation and the peopling of Japan.
TLDR
Four loci mapping to the nonrecombining portion of the Y chromosome were genotyped in Japanese populations from Okinawa, the southernmost island of Japan; Shizuoka and Aomori on the main island of Honshu; and a small sample of Taiwanese, confirming the irregular distribution of this polymorphism in Asia. Expand
Genetic evidence on the origins of Indian caste populations.
TLDR
It is concluded that Indian castes are most likely to be of proto-Asian origin with West Eurasian admixture resulting in rank-related and sex-specific differences in the genetic affinities of castes to Asians and Europeans. Expand
Genetic studies of the Roma (Gypsies): a review
TLDR
To be most productive, future studies of the epidemiology of single gene disorders should take social organisation and cultural anthropology into consideration, thus allowing the targeting of public health programs and contributing to the understanding of population structure and demographic history of the Roma. Expand
The emerging tree of West Eurasian mtDNAs: a synthesis of control-region sequences and RFLPs.
TLDR
It is shown that the main indigenous North African cluster is a sister group to the most ancient cluster of European mtDNAs, from which it diverged approximately 50,000 years ago. Expand
Y-chromosomal diversity in Europe is clinal and influenced primarily by geography, rather than by language.
TLDR
These patterns retain a strong signal of expansion from the Near East but also suggest that the demographic history of Europe has been complex and influenced by other major population movements, as well as by linguistic and geographic heterogeneities and the effects of drift. Expand
Pre-Caucasoid and Caucasoid genetic features of the Indian population, revealed by mtDNA polymorphisms.
TLDR
The hypothesis that the DdeI(10,394)AluI (10,397) (++) haplotype predated the Indo-European invasion and probably the split between proto-Indians and proto-Orientals is strongly supported. Expand
Geographic patterns of mtDNA diversity in Europe.
TLDR
The distribution of the zones of highest mitochondrial variation (genetic boundaries) confirmed that the Saami are sharply differentiated from an otherwise rather homogeneous set of European samples, and an area of significant clinal variation was identified around the Mediterranean Sea (and not in the north), even though the differences between northern and southern populations were insignificant. Expand
mtDNA variation among Greenland Eskimos: the edge of the Beringian expansion.
TLDR
The data are in agreement with the view that the present Greenland Eskimos essentially descend from Alaskan Neo-Eskimos, and major mtDNA types shared between Na Dene and Eskimo are demonstrated. Expand
