Further evidence for the South Asian origin of the Romanis came in the late 1990s. Researchers doing DNA analysis discovered that Romani populations carried large frequencies of particular Y chromosomes (inherited paternally) and mitochondrial DNA (mtDNA) (inherited maternally) that otherwise exist only in populations from South Asia.

47.3% of Romani men carry Y chromosomes of haplogroup H-M82, which is rare outside South Asia.[16] Mitochondrial haplogroup M, most common in Indian subjects and rare outside southern Asia, accounts for nearly 30% of Romani people.[16] A more detailed study of Polish Roma shows this to be of the M5 lineage, which is specific to India.[17] Moreover, a form of the inherited disorder congenital myasthenia is found in Romani subjects. Caused by the 1267delG mutation, it is otherwise known only in subjects of Indian ancestry. This is considered to be the best evidence of the Indian ancestry of the Romanis.[18]
