Haplogroup J is a human mitochondrial DNA (mtDNA) haplogroup. The clade derives from the haplogroup JT, which also gave rise to haplogroup T. Within the field of medical genetics, certain polymorphisms specific to haplogroup J have been associated with Leber's hereditary optic neuropathy. [2]

Origin

Around 45,000 years before present, a mutation took place in the DNA of a woman who lived in the Near East or Caucasus. Further mutations occurred in the J line, which can be identified as the subclades J1a1, J1c1 (27,000 yrs ago), J2a (19,000 yrs ago), J2b2 (16,000 years ago), and J2b3 (5,800 yrs ago). Haplogroup J bearers along with persons carrying the T mtDNA clade settled in Europe from the Near East during the late Paleolithic and Mesolithic.

However, any statements concerning the geographic origin of this or any other haplogroup are highly speculative and considered by most population geneticists to be 'story telling' and outside the domain of science.[ citation needed ] Furthermore, inferring close associations between a haplogroup and a specific archaeological culture can be equally problematic.

Distribution

Projected spatial frequency distribution for haplogroup J.

Basal haplogroup J* is found among the Soqotri (9.2%). [4]

The average frequency of haplogroup J as a whole is today highest in the Near East (12%), followed by Europe (11%), the Caucasus (8%) and Northeast Africa (6%). Of the two main sub-groups, J1 takes up four-fifths of the total and is spread widely on the continent while J2 is more localised around the Mediterranean, Greece, Italy/Sardinia and Spain.

There is also limited evidence that the subclade J1 has long been present in Central Asia. For instance, perhaps the highest incidence of haplogroup J is the 19% of Polish Roma, who belong to J1 (although this has also been ascribed to a "founder effect" of some kind). [5] In Pakistan, where West Eurasian lineages occur at frequencies of up to 50% in some ethno-linguistic groups, the incidence of J1 averages around 5%, while J2 is very rare. However, J2 is found amongst 9% of the Kalash minority of north-west Pakistan. [6]

In the Arabian peninsula, mtDNA haplogroup J is found among Saudis (10.5–18.8% J1b) and Yemenis (0–20% J1b). The J1b subclade also occurs in the Near East among Iraqis (7.1%) and Palestinians (4%). [7]

In Africa, haplogroup J is concentrated in the northeast. It is found among Algerians (3.23–14.52%), [8] as well as Sudanese Copts (10.3% J1a; 10.3% J2), [9] Sudanese Fulani (10.7% J1b), [9] Meseria (6.7% J1b), [9] Arakien (5.9% J1b), [9] Egyptians (5.9%), [10] Mozabite Berbers (3.53%), [8] Sudanese Hausa (2.9% J1b), [9] Zenata Berbers (2.74%), [8] Beja (2.1% J1b), [9] and Reguibate Sahrawi (0.93%). [8]

Within Europe, >2% frequency distribution of mtDNA J is as follows: [11]

Haplogroup J has also been found among ancient Egyptian mummies excavated at the Abusir el-Meleq archaeological site in Middle Egypt, which date from the Pre-Ptolemaic/late New Kingdom, Ptolemaic, and Roman periods. [12] Haplogroup J has been observed in ancient Guanche fossils excavated in Gran Canaria and Tenerife on the Canary Islands, which have been radiocarbon-dated to between the 7th and 11th centuries CE. All of the clade-bearing individuals were inhumed at the Tenerife site, with one specimen found to belong to the J1c3 subclade (1/7; ~14%). [13] The J clade has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Afalou prehistoric site. Around 22% of the observed haplotypes belonged to various J subclades, including undifferentiated J (1/9; 11%) and J1c3f (1/9; 11%). [14]

In Eastern Siberia, haplogroup J1c5 has been observed in samples of Yakuts (3/111 = 2.7% Vilyuy Yakut, [15] 2/148 = 1.4% Northern Yakut, [15] 1/88 = 1.1% Central Yakut, [16] 1/164 = 0.6% Central Yakut [15] ), Evenks in Yakutia (4/125 = 3.2% [15] ), and Evens in Yakutia (1/105 = 1.0% [15] ). Haplogroup J2a2b3 has been observed in a sample of Nyukzha Evenks (2/46 = 4.3% [16] ). Haplogroup J2 also has been observed in a sample of Evenks collected in Olenyoksky District, Zhigansky District, and Ust-Maysky District of Yakutia (7/125 = 5.6% [15] ). One instance of haplogroup J1c10a1 has been observed in the Human Genome Diversity Project's sample of ten Oroqen individuals from northernmost China.

Tree

This phylogenetic tree of haplogroup J subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation [1] and subsequent published research.

Genetic traits

It has been theorized[ by whom? ] that the uncoupling of oxidative phosphorylation related to SNPs which define mt-haplogroup J consequently produces higher body heat in the phenotype of mtDNA J individuals. This has been linked to selective pressure for the presence of the haplogroup in northern Europe, particularly Norway. [17] Individuals from haplogroups UK, J1c and J2 were found to be more susceptible to Leber's hereditary optic neuropathy because they have reduced oxidative phosphorylation capacity, which results in part from lower mtDNA levels. [18] J mtDNA has also been associated with HIV infected individuals displaying accelerated progression to AIDS and death. [19] The T150C mutation, which is exclusive to but not definitive of, the J2 subclade of Haplogroup J may be part of a likely nuclearly controlled general machinery regarding the remodeling & replication of mtDNA. Controlling a remodeling which could accelerate mtDNA replication thus compensating for oxidative damage in mtDNA as well as functional deterioration occurring with old age related to it. [20] Haplogroup J was found to be a protective factor against ischemic cardiomyopathy. [21] It was also found that Haplogroup J was a protective factor among osteoarthritis patients from Spain [22] but not from UK, [23] and this was hypothesized to be due to a different genetic composition (polymorphisms) of the Haplogroup J in both populations. A study involving patients of European and West Asian origin or descent showed that individuals classified as haplogroup J or K demonstrated a significant decrease in risk of Parkinson's disease versus individuals carrying the most common haplogroup, H.

<span class="mw-page-title-main">Haplogroup</span> Group of similar haplotypes

A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual.

<span class="mw-page-title-main">Human Y-chromosome DNA haplogroup</span> Human DNA groupings

In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). The Y-chromosome accumulates approximately two mutations per generation, and Y-DNA haplogroups represent significant branches of the Y-chromosome phylogenetic tree, each characterized by hundreds or even thousands of unique mutations.
