Romany Migration from Indo-Pakistan Haplotype J1
Malyarchuk proposes a Romani linkage to J1 distribution from the Indo-Pakistani region via Romany migration to Europe, also previous research into J1 distribution among ethnicities of India and Pakistan.

"Previously, we have found that the Polish Roma population is characterized by high incidence (18.8%) of haplogroup J1* lineage, defined by HVS I motif 16069–16126-16145–16222-16235–16261-16271 (Malyarchuk et al. 2006a). This and a similar haplotype, lacking only the 16271 transition, are very rare in European Roma populations, being found only in the Spanish, Bulgarian and Hungarian Roma (Gresham et al. 2001; Egyed et al. 2007).
Among Europeans, such haplotypes have been revealed only in French (0.5%; Dubut et al. 2004), Hungarian (0.5%; Egyed et al. 2007) and Czech (about 3%; Vanecek et al. 2004; Malyarchuk et al. 2006b) populations.
In the present study, we have found that 2.9% of individuals from eastern Slovakia are characterized by exactly the same J1*-haplotype. Taking into account its similarity with J1-haplotypes revealed in Southwestern Pakistani populations (Quintana-Murci et al. 2004) and thus assuming that this haplotype might have been characteristic of the ancestral Romani population (Malyarchuk et al. 2006a), we completely sequenced two J1*-samples revealed in Slovakia (Fig. 2). Comparison with published data (pooled in MitoMap mtDNA tree (Ruiz-Pesini et al. 2007)) demonstrated that these J1*-haplotypes belong to a new subhaplogroup J1a defined by transition at 8460.
This subhaplogroup appears to be a sister clade to subhaplogroup J1b. Therefore, the J1a contribution to the Roma, and through them to some European gene pools, can be caused by gene flow from Indo-Pakistani region.
One of the haplogroup J Slovak sample (Slv174; 16069–16126–16261–73–263–295) was characterized by uncertain HVS II motif, due to the lack of any subhaplogroup-diagnostic mutation according to classification developed in Palanichamy et al. (2004) and Carelli et al. (2006). To determine its phylogenetic status, we completely sequenced this sample and found that it belongs to subhaplogroup J1c being accompanied by transition at 14798, despite the lack of diagnostic mutation at position 228. It is unclear however, whether this sample should occupy the ancestral node for J1c-phylogeny or it is the result of back-mutation at position 228 (Fig. 2)."
