Haplogroup H-M82 is a major lineage cluster in the Roma, especially Balkan Roma, among whom it accounts for approximately as high as 60% of males. A 2-bp deletion at M82 locus defining this haplogroup was also reported in one-third of males from traditional Roma populations living in Bulgaria, Spain, and Lithuania. High prevalence of Asian-specific Y chromosome haplogroup H-M82 supports their Indian origin and a hypothesis of a small number of founders diverging from a single ethnic group in India (Gresham et al. 2001).
