This haplogroup is found at a high frequency in [[South Asia]]. It is generally rare outside of the [[South Asia]] but is common among the [[Romani people]], particularly the H-M82 subgroup.

It is a branch of [[Haplogroup F (Y-DNA)|Haplogroup F]], and is believed to have arisen in India between 20,000 and 30,000 years ago. Its probable site of introduction is India since it is concentrated there. It seems to represent the main Y-haplogroup of the indigenous paleolithic inhabitants of India, because it is the most frequent Y-haplogroup of tribal populations (25-35%). On the other hand, its presence in upper castes is quite rare (ca. 10%).<ref>{{cite journal |author=Cordaux R, ''et al.'' |title=Independent Origins of Indian Caste and Tribal Paternal Lineages |journal=Current Biology |volume=14 |pages=231–5 |year=2004 |pmid=14761656 |issue=3 |doi=10.1016/j.cub.2004.01.024}}</ref>

In human genetics, Haplogroup H (M69) is a Y-chromosome haplogroup.

This haplogroup is found at a high frequency in South Asia. It is generally rare outside of the South Asia but is common among the Romani people, particularly the H-M82 subgroup.

Origins

It is a branch of Haplogroup F, and is believed to have arisen in India between 20,000 and 30,000 years ago. Its probable site of introduction is India since it is concentrated there. It seems to represent the main Y-haplogroup of the indigenous paleolithic inhabitants of India, because it is the most frequent Y-haplogroup of tribal populations (25-35%). On the other hand, its presence in upper castes is quite rare (ca. 10%).[1] [2] [3]

Distribution

South Asia

Haplogroup H is frequently found among populations of India, Sri Lanka, Nepal, and Pakistan.

In India, Haplogroup H-M69 has been found in 27.2% (110/405) of a sample of unspecified ethnic composition from southern India.[4][5] Another study has found haplogroup H-M69 in 26.4% (192/728) of an ethnically diverse pool of samples from various regions of India.[2]

In Sri Lanka, Haplogroup H-M69 has been found in 25.3% (23/91) of a sample of unspecified ethnic composition[4][5] and in 10.3% (4/39) of a sample of Sinhalese.[6]

In Nepal, one study has found Haplogroup H in approximately 12% of a sample of males from the general population of Kathmandu (including 4/77 H1a-M82, 4/77 H1*-M52(xH1a-M82), and 1/77 H*-M69(xH1-M52, H2-Apt)) and in 6% of a sample of Newars (4/66 H1a-M82).[7]

In Pakistan, Haplogroup H1-M52 has been found in 4.1% Burusho, 20.5% Kalash, 4.2% Pashtun, and 2.5% other Pakistanis.[8] Another study has found haplogroup H in approximately 8% (3/38) of a sample of Burusho (also known as Hunza), including 5% (2/38) H1a*-M82(xH1a1-M36, H1a2-M97, H1a3-M39/M138) and 3% (1/38) H1a1-M36.[9]

Romani people

Haplogroup H1a-M82 is a major lineage cluster in the Balkanic Romani population, accounting for approximately 60% of the total.[10] A 2-bp deletion at M82 locus defining this haplogroup was also reported in one-third of males from traditional Romani populations living in Bulgaria, Spain, and Lithuania (Gresham et al. 2001). Its ancestral M52 A C transversion was reported in the Vlax Roma (Kalaydjieva et al. 2001) and India (Ramana et al. 2001; Wells et al. 2001; Kivisild et al. 2003). High prevalence of Asian-specific Y chromosome haplogroup H1 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).

Central Asia and the Middle East

Haplogroup H has been found very rarely outside of the Indian subcontinent and the Romani populations, including approximately 12.5% (2 out of 16 individuals) H1-M52 in a sample of Tajiks from Dushanbe,[11] 6% (1/17) H1-M52 in a sample of Kurds from Turkmenistan,[11] 5% (1/20) H-M69 in a sample of Syrians,[12] 4% (2/45) H1-M52 in a sample of Uzbeks from Samarkand,[11] 4% (2/53) H1-M52 in a sample of Iranians from Samarkand,[11] 3% (2/70) H1-M52 in a sample of Uzbeks from Khorezm,[11] 3% (1/38) H1a-M82 in a sample of Balkarians,[13] 2.6% (3/117) H1a-M82 in a sample from southern Iran,[14] 2% (1/41) H1-M52 in a sample of Uyghurs from Kazakhstan,[11] 1% (1/92 H1a-M82)[13] to 2% (1/50 H-M69)[12] of Ukrainians, 2% (1/56) H1-M52 in a sample of Uzbeks from Bukhara,[11] 2% (1/57) H1a-M82 in a sample of Macedonian Greeks,[13] 2% (1/63) H1-M52 in a sample of Uzbeks from the Fergana Valley,[11] 0.9% (1/113) H1a-M82 in a sample of Serbians,[10] 0.6% (3/523) H-M370 in a sample of Turks,[15] and 0.5% (1/201) H1-M52 in a sample of Somali immigrants to Denmark.[16]

In the Arabian Peninsula, Haplogroup H has been found in 4.3% (7/164) of males from the United Arab Emirates (including 4/164 = 2.4% H*-M69(xH1-M52, H2-Apt) and 3/164 = 1.8% H1a-M82),[17] approximately 2% of males from Oman,[18] 1.9% (3/157) of males from Saudi Arabia (including 2/157 = 1.3% H-M69(xH1-M52) and 1/157 = 0.6% H1a-M82),[19] and 1.4% (1/72 H1a-M82) of males from Qatar.[17]

The rare subclade H2-Apt has been found in 1.3% (1/77) of a sample of Greeks.[8]

East and Southeast Asia

At the easternmost extent of its distribution, Haplogroup H has been found in Balinese (19/551 = 3.45% H-M69),[5] Tibetans (3/156 = 1.9% H*-M69(xH1-M52, H2-Apt)),[7] and Mongolians (1/149 = 0.7% H-M69).[4] The subclade H1a3-M39/M138 has been observed in the vicinity of Cambodia, including one instance in a sample of six Cambodians[2] and one instance in a sample of 18 individuals from Cambodia and Laos.[9]
