GenBank is a database of genetic sequence data. (2013) as a Bell Beaker site, but which is more likely a late Corded Ware or early Unetice site. The current build is #17. Regarding T1, the only deep clade that could been linked to the Indo-European migrations is T1a1a and its subclade T1a1a1, which Pala et al estimate to be respectively 11,000 years old and 6,800 years old. It says I'm T2 and I have a T2b match . The problem with haplogroup T is that all of the top subclades found in Europe (T1a, T2b, T2c, T2e) are also found in these regions. T1a2 is found both in northern Europe and southern Africa but is … Nonetheless, the maternal lineages recovered in Germany and Switzerland display a strong continuity with Neolithic samples from the same region, and could have been absorbed by the Indo-European male invaders. Nevertheless, the origin of T2b* seems to be a predominant Western/Central European haplogroup. These branches of haplogroup K are found at levels of 30% among Ashkenazi. The highest frequencies of mtDNA T1 are observed among the Udmurts (15%) of the Volga-Ural region of Russia, followed by Romania (6%) and the southern Balkans (Bulgaria, Macedonia, Albania, all 4.5%), the northern Fertile Crescent (Lebanon, Iraq, eastern Turkey, all around 5.5%), the South Caucasus (Armenia, Georgia, Azerbaijan, 4.5% to 5.5%), then Austria and the Czech Republic (3.5%). Sequeira, A., Rollins, B., Magnan, C., van Oven, M., Baldi, P., Myers, R.M., Barchas, J.D., Schatzberg, A.F., Watson, S.J., Akil, H. and Bunney, W.E. The mutation defining haplogroup T happened some time around 29,000 years ago, probably in the East Mediterranean region. But these are mtDNA, not Y-dna. A quote in Fig. E1a1b1 is the marker for ASHKENAZI, but T2e is now considered the marker for Sephardi. The authors of the same study identified two polymorphisms associated with achieving the elite performance level: 16080G and 16362C. (2001) analysed the presumptive remains of Jesse James (1847-1882), the famous American outlaw, gang leader, bank robber, train robber from the US state of Missouri. The term haplogroup is a combination of haplotype and group. (2016). Thus, T2b, which occurs at an almost non-existent level in Iraq, and reaches a high of 4.2% in Great Britain, is completely lacking in the Cherokee sample. T samples belonging to T1a1'3, T2a1b1, T2b (including T2b3a and T2b23a), T2c (incl. Early Neolithic skeletons (dating from c. 6350 BCE) from north-western Anatolia were tested by Mathieson et al. Highest frequencies more prevalent in North Italians … The genetic history of the British Isles is the subject of research within the larger field of human population genetics.It has developed in parallel with DNA testing technologies capable of identifying genetic similarities and differences between both modern and ancient populations. Author: Maciamo Hay. T2a1b1 was found by Keyser et al. ... Ireland (3313)-1 T2 Poland (1413) Ashkenazi 1 T2 Russia (850)-1 T2 United Kingdom (2423)-1 T2b Germany (3922) Ashkenazi 1 High Resolution Matches (HVR1+HVR2) Haplogroup Country Comment Count T2 Germany (996)-1 Tags: None. After that T2 is most frequently encountered in the Netherlands (12%), Sardinia (10%), Iceland (10%), Switzerland (9.5%), Hungary (8.5%) and Ukraine (8.5%), as well as among many ethnic groups around the Caucasus such as the Kumyks (10%), Azeri (9.5%) and Georgians (9%). These were 199C (found in T2b3d), 16298C (found in T2f1a) and 16325C (found in T1a1m, T1a8a and T3). T2b is subdivided in 30 basal subclades (+ their own ramifications) to date, twice more than all other T2 subclades combined. (2007) found that mtDNA haplogroup T is negatively associated with elite endurance athletic status. (2012), haplogroup T appears to be protective against type 2 diabetes. been found in Neolithic Europe are T2b2b and T2b4f. Editor’s note: This post has been corrected from the original, which gave the incorrect location of Jesse James’ grave. Hi, I just have a few questions on MTDNA results. Note that T2b2 and T2b4 happen to be the same subclades as those recovered from Corded Ware remains. Ruiz-Pesini et al. Several millennia later it would have been carried to Central Asia, then Iran and the Near East by the Indo-Iranian R1a-Z93 invaders. Already a celebrity when he was alive, he became a legendary figure of the Wild West after his death. (2014) tested 15 mtDNA sequences (6800-6000 BCE) from the PPNB in Syria, but no T2 was found in any of the sites. Her mitochondrial DNA is haplogroup T2b. The haplogroup spread into Europe with the early farmers from the Near East. Contacts between tribes of European hunter-gatherers would have allowed T lineages to join Y-haplogroups I1, I2 and R1a during the Mesolithic period. It is provided at the request of readers. Haplogroup T2b is a branch on the maternal tree of human kind. A few branches of haplogroup K, such as K1a9, K2a2a, and K1a1b1a, are specific to Jewish populations and especially to Ashkenazi Jews, whose roots lie in central and eastern Europe. Haplogroup J2, as previously discussed, is often incorrectly equated with J1 and described as “Jewish” or “Semitic,” despite the fact that it … The ratio of sister subhaplogroups T2e to T2b was found to vary 40-fold across populations from a low in the British Isles to a high in Saudi Arabia with the ratio in … It is certain that haplogroup T played an important role in the diffusion of agriculture across Europe. T samples belonging to T1a1’3, T2a1b1, T2b (including T2b3a and T2b23a), T2c (incl. (2015). Centered around Near Eastern, European and Caucasian maternal lineages. (2016) analysed dozens of samples from the Pre-Pottery Neolithic sites in Israel, Jordan and Iran and did not find any trace of T2b (although two T1a and one T2c were present in Jordan). and Prokhortchouk, E.B. The known history for haplogroup H2 is very general; women with this haplogroup survived and reproduced very successfully in Europe during the Last Ice Age. T2b was by far the most successful, accounting for roughly half of all T2 individuals in Europe. The paternal haplogroups corresponding to these lineages might have been E-M78 and J2b, two haplogroups thought to have settled in Southeast Europe in the Late Glacial or immediate postglacial period too. I am working on changing results over to build 17. R1b is the most common haplogroup in Western Europe, reaching over 80% of the population in Ireland, the Scottish Highlands, western Wales, the Atlantic fringe of France and the Basque country. The Corded Ware culture is associated with the expansion of Y-haplogroup R1a from the northern Russian steppe, while Unetice marks the arrival of R1b lineages around modern Germany. He was the most famous member of the James-Younger Gang. Haplogroup T is composed of two main branches T1 and T2. The T maternal clade is thought to have emanated from the Near East (Bermisheva 2002). Author: Rebekah A. Canada | Copyright: National Geographic. (1996) sequenced the mitochondrial DNA of Grand Duke of Russia Georgij Romanov in order to establish the authenticity of the remains of his brother, Tsar Nicholas II of Russia. Haplogroup T is composed of two main branches T1 and T2. Derenko, M., Malyarchuk, B., Bahmanimehr, A., Denisova, G., Perkova, M., Farjadian, S., & Yepiskoposyan, L. (2013). Nevertheless, the origin of T2b* seems to be a predominant Western/Central European haplogroup. Distribution of mtDNA haplogroup T2 in Europe, North Africa and the Middle East. and Peña, J.A. In far western Ireland, haplogroup R and subgroups reach nearly 100% today. Mitochondrial clade T derives from the haplogroup JT, which also gave rise to the mtDNA haplogroup J. and Pereira, L. (2009). The highest frequencies of mtDNA T1 are observed among the Udmurts (15%) of the Volga-Ural region of Russia, fo… The grandmother had a surname that was also a … Note: GenBank results currently use Phylotree build 16. The mt‐haplogroup was assigned to T2b (Vianello et al., 2013). (2000) reported that men belonging to haplogroup T have the highest risk of asthenozoospermia (reduced sperm motility). and Parsons,T.J. H7 was probably part of the Neolithic migration from the Carpathians to Ukraine that gave rise to the Dnieper-Donets culture, along perhaps with mt-haplogroups K1c, K2b, T1a1a, T2a1b1 and T2b, and with Y-haplogroups G2a3b1 and J2b2. The latter defines the T1a13, T2b16 and T2i clades, which therefore may have increased athletic predispositions. Belarus) and the North Caucasus / found in Chalcolithic Poland (Corded Ware culture) and in Bronze Age Serbia, T2b16: found in Estonia, Russia (Volga Tatars) and Kazakhstan, T2b19: found in Italy and England / found in EBA Alsace, T2c1: found in Iran, Iraq, the Arabian peninsula, Italy, Sardinia, Spain and Central Europe / found in Early Neolithic Italy, T2c1a: found in Portugal, France, Italy and among Iraqi Jews / found in MLBA Jordan and Israel (Tell Megiddo), T2c1d: found in Britain, Ireland, the Netherlands, Belgium, France, Italy (Sardina), Spain, Germany, Denmark, Norway, Finland and Iran (Qashqai) / found in Late Neolithic France, England and Orkney, in EBA Moldova (Cucuteni-Trypillia culture) and in EBA France, T2c1e: found in Britain, Germany, Poland, Hungary and Turkey, T2c1f: found in France, Italy, Germany, Turkey and Iran / found among Iron Age Latins, T2d1: found in India, Siberia, Mongolia and the Netherlands, T2d1b: found in Poland, Iran (Persians), Siberia and Mongolia, T2d2: found in Iran, Georgia, Russia, Spain and Italy, T2e1: found mostly in northern and Mediterranean Europe, Egypt and the Arabian peninsula, but also in Iran, Pakistan and Uzbekistan / found in Neolithic Scotland, in Bell Beaker Poland, and in Bronze Age Poland, T2e1a : found in Britain, the Netherlands and Spain / found in Late Neolithic England (Bell Beaker), T2e1b : found in Germany, Romania and Russia, T2e2a : found in Britain, Germany, Sweden and Finland / found in Bronze Age Bulgaria, T2f1: found in north-western, central and eastern Europe and in Central Asia (Turkmenistan), T2f1a: found in Britain, Ireland, France, Germany, Scandinavia and Finland, T2f2: found in Finland, Sweden, Germany, France, Italy, the Balkans, Anatolia, the South Caucasus and the north of the Black Sea, T2f4: found in Britain and France / found in Neolithic Scotland, T2f5: found in Norway, Britain and Ireland, T2f7: found in Germany, Scandinavia and Finland, T2g1: found in Italy, Britain, Sweden, Latvia, Lithuania, Hungary, Turkey, Egypt, Iran (Persians, Qashqai, Jews) and Siberia (Yakuts), T2g2: found in Hungary and Scotland / found in Bell Beaker Germany<, T2g2a (formerly T3): found in Austria, Britain and Sweden. It is certain that haplogroup T played an important role in the diffusion of agriculture across Europe. One of the most engaging features of 23andMe’s Personal Genome Service is a customer’s ability to trace his or her genetic ancestry using the mitochondrial DNA and the Y-chromosome. T2* is essentially a West Eurasian haplogroup. National Geographic Geno 2.0 Text (2004). In addition to GenBank samples, listings below may include other samples published but not submitted to GenBank such as those from the HapMap project. The following members of the community offer paid consulting for those seeking help with mtDNA results. There are a few pages of Spencer Wells book, "Deep Ancestry, Inside the Genographic Project," that include information about the mtDNA Haplogroup T2b. The most recent subclades are T2b, T2e and T2g, which date from 10,000 years before present, during the Pre-Pottery Neolithic period. It is also common in Anatolia and around the Caucasus, in parts of Russia and in Central and South Asia. Haplogroup E3b is often incorrectly described as “African,” leaving a misimpression regarding the origin and complex history of this haplogroup. Gasparre, G., Porcelli, A.M., Bonora, E., Pennisi, L.F., Toller, M., Iommarini, L., Ghelli, A., Moretti, M., Betts, C.M., Martinelli, G.N. (2002) reported three other polymorphisms associated with increased VO2max and athletic performance (especially for endurance). Fendt, L., Zimmermann, B., Daniaux, M. and Parson, W. (2008). T2s with 304 are called T2b; those that have 292 are T2c instead of obsolete Richards' name "T3". The complete lack of T2b, or any T2 but one T2c, in the Fertile Crescent during the Early Neolithic period supports Pala et al. It is thought that some E1b1a populations later migrated to West Africa across a Sahara that was moist savannah/grassland. This is a list of haplogroups of notable people. My maternal group was assigned as T2b2b per National genographic Geno 2.0... haven't had all the mtDNA testing yet... but according to FTDNA origins and their kits that are T2b2b - it's 3 times as common in Ireland as anywhere else (2nd is Scotland) and that lines up well with my maternal line, which is from somewhere in the SW or W of Ireland . 's hypothesis that several T2 lineages would have occupied western Anatolia and south-east Europe during the Mesolithic, and would have consequently have been assimilated by the wave of Neolithic farmers before spreading all over Europe. Today, it is present at the highest frequencies in Croatia (12 percent), Tunisia (9 percent), and Greece (5 percent). They also compared the sequence to that of twi living matrilineal relatives. ... K1, K2, N*, N1, T1a, T2b, T2c, T2e, T2f, U3, W, X1, X2, and many subclades of H (including H2, H5, H7, H13 and H20). If you belong to T1, please join the T1 project instead. Data from outside Europe is still sparse, but among the deeper subclades identified in Central/South Asia were T2b2 (in Turkmenistan, Iran and India), T2b4 (in Uzbekistan), T2b11 (found in the North Caucasus) and T2b16 (found in the Volga-Ural and Kazakhstan). (2012). Haplogroup H (mtDNA) Haplogroup H is the most common haplogroup in Europe, the Near East, and the Caucasus. Wilde et al. The two of them have very different distributions, which are diametrically opposed in most regions. Haplogroups T* (perhaps T1a) and T2b have been found in skeletons from late Mesolithic hunter-gatherers respectively from Russia and Sweden. T1 and T2 split from each others some 21,000 years ago, toward the end of the Last Glacial Maximum (c. 26,500 to 19,000 years before present). According to Pala et al., it is one of the T subclades that penetrated into Europe during the Late Glacial period. Pages 71-73 and page 101. I'm posting for you a migratory map of Haplogroup mtDNA T (as well a J) from when T first formed some 28,000 years ago between the Black and Caspian sea's and so you can see in the darkened areas where the european branch first dispersed up north into the Pontic Steppe and then slowly morphed southwestwardly into eastern europe. T2e is called the SISTER of T2b. The "Celtic" Irish people of the emerald isle of Ireland are closely related to the Scottish people of nearby Scotland, and Irish and the partly Frisian-Anglo-Saxon English people from England are also significantly related. H2b is a subclade, or branch of, the more ancient haplogroup H. So, let’s start there and work our way down to H2b. Distribution of mtDNA haplogroup T1 in Europe, North Africa and the Middle East. Studies by Stanger et al. Learn how your comment data is processed. Age: 10,069.6 ± 1,610.0; CI=95% (Behar et al., 2012b) Origin: West Asia Variants: G930A G5147A T16304C FTDNA Tree: Link Parent Branch: T2 Descendant branch(s): T2b1 T2b15 T2b2 T2b22 T2b23 T2b3 T2b30 T2b31 T2b32 T2b33 T2b34 T2b35 T2b36 T2b37 T2b4 T2b5 T2b6 T2b7 T2b8 T2b9. In Iran, it is about 4 percent of maternal lineages, and it is about 3 percent of maternal lineages in Armenia. Its age is between 8,500 and 11,700 years (Behar et al., 2012b). (2014) analysed the mtDNA of 395 elite Polish athletes (213 endurance athletes and 182 power athletes) and 413 sedentary controls, found that members of haplogroup T were as common among athletes as in the control group. Furthermore, T1a1a1 is particularly common in countries with high levels of Y-haplogroup R1a, such as Central and Northeast Europe, but also everywhere in Central Asia and deep into North Asia, as far east as Mongolia. Stone et al. If you are defined as T only, please join the T mtDNA other (not T1 or T2) project instead. Her female-line descendants include a great number of European nobles, such as Charles I of England, George I, George III and George V of Great Britain, Frederick William I of Prussia, Charles X Gustav of Sweden, Gustavus Adolphus of Sweden, Maurice of Nassau, Prince of Orange, Olav V of Norway, and George I of Greece. Schonberg, Anna; Theunert, Christoph; Li, Mingkun; Stoneking, Mark & Nasidze, Ivan (2011). Nowadays, T2a1b is found mostly in eastern, central and Mediterranean Europe, but has also been found in the British Isles, Scandinavia, the Caucasus, Kazakhstan, Iran, Turkey, Palestine, Egypt and Yemen. It is about 7 percent of the population in Bulgaria. It could consequently have belonged to tribes of hunter-gatherers who migrated to Northeast Europe and mixed with R1a populations there. The two of them have very different distributions, which are diametrically opposed in most regions. For many mt-haplogroups it is relatively easy to distinguish subclades that were dispersed by the Indo-European migrations during the Bronze Age by looking at the European mtDNA lineages found in Siberia, Central Asia and South Asia, regions that have been settled by the Indo-Europeans during the Bronze Age. Interestingly, T2a1b was also found at a Bronze Age site in the Harz mountains in central Germany, described by Brandt et al. Required fields are marked *. The total of 11312749 reads mapped to the human genome. Haplogroup E1b1 likely originated in the highlands of Ethiopia in East Africa, and diverged into two subclades, E1b1a and E1b1b, around 26,000 years ago. The geographic distribution within subclade T2 varies greatly with the ratio of subhaplogroup T2e to T2b reported to vary 40-fold across examined populations from a low in Britain and Ireland, to a high in Saudi Arabia (Bedford 2012). Malyarchuk, B., Derenko, M., Grzybowski, T., Perkova, M., Rogalla, U., Vanecek, T. and Tsybovsky, I. It is maintained by Dr. Mannis Van Oven. Its age is between 16,800 and 21,900 years (Behar et al., 2012b). Centered around Near Eastern, European and Caucasian maternal lineages. and Ceroni, A.R. As a result, there are high chances that these two subclades were found among the Bronze Age Proto-Indo-Europeans, particularly with Y-haplogroup R1a (associated with the Balto-Slavic and Indo-Iranian branches). It is run by the United States National Institute of Health. Inclusion on this list is not a recommendation or endorsement of any service. It is provided at the request of readers. T1a, however, was found among the very first farmers in the Levant. The mtDNA all matched and fitted into haplogroup T2 (with heteroplasmy at position 16169). The male samples tested from the same site belonged R1a. Many of these lineages would have settled at first in Southeast Europe. Haplogroup T2 is a branch on the maternal tree of human kind. Let’s say your haplogroup under 23andMe’s previous tree was H2. Note that the depth of the phylogenetic tree has been reduced to four subclades downstream of T* (except for T1a1a) to facilitate its reading. Paternal and Maternal Haplogroups in Prehistoric Europe ... A1a has been found in modern populations as far north as Ireland, Scotland, Scandinavia and Finland. Last update July 2020. They would later have been diffused around Europe by Neolithic agriculturalists after intermingling with the inhabitants of Southeast Europe. (2012) suggested that some J and T lineages recolonised Europe from the Near Eastern refugia during the Epipaleolithic, following the end of the last glaciation and the melting of the icecaps covering central and northern Europe. (2009) in Bronze Age samples related to the Andronovo culture from the Krasnoyarsk area in southern Siberia. However, a more detailed study by Maruszak et al.

Haplogroups T1 and T2 were also part of the Bronze Age samples retrieved from the Corded Ware culture (T1a, T1a1'3, T2, T2b2b, T2b4f, T2c) and the Unetice culture (T2b, T2c), both in Central Europe. T2c1d1), T2e and T2f have been found in remains from the Linear Pottery culture (LBK) in Central Europe, and the Cucuteni-Trypillian culture in Ukraine. Note: This information does not imply an endorsement of YFull or their methods. Kılınç et al (2016) sequenced nine Pre-Pottery Neolithic genomes (c. 8300 to 6300 BCE) from Central Anatolia, while Fernández et al. Costa, M.D., Cherni, L., Fernandes, V., Freitas, F., el Gaaied, A.B.A. Your email address will not be published. (2013). Samples come both from published academic literature and donations from genetic genealogy community members. They hypothesise that T1a1, T2a1b, T2b, T2e and T2f1 entered Europe from Anatolia in the Late Glacial period, while T2b and T2e followed in the immediate postglacial period from 11,000 years ago. Being in T2 is somewhat more wide term than "to fall into T2 or T3". However since the samples are contemporary to Neolithic cultures in the rest of Europe, it is not certain that T lineages didn't come through intermarriages between farmers and hunter-gatherers. Jesse James's remains were compared against two maternal relatives and all were found to belong to mt-haplogroup T2. Haplogroup T1 is not found among the Saami, the Jews, or the Avars of the Caucasus, and is extremely rare in Jordan, Morocco, northern Spain, Bosnia and Croatia. Copyright © 2013 - 2021 Rebekah A.

Pala, Maria; Olivieri, Anna; Achilli, Alessandro; Accetturo, Matteo; Metspalu, Ene; Reidla, Maere; Tamm, Erika; Karmin, Monika; Reisberg, Tuuli; Kashani, Baharak H.; Perego, Ugo A.; Carossa, Valeria; Gandini, Francesca; Pereira, Joana B.; Soares, Pedro; A (2012). The Rathlin males, all haplogroup R1b, combined with evidence provided by later genetic analysis of passage grave remains point decisively towards a population replacement – with haplogroup R males replacing the previous inhabitants of both Europe and the British Isles. The total of 11312749 reads mapped to the human genome. T2c1d1), T2e and T2f have been found in remains from the Linear Pottery culture (LBK) in Central Europe, and the Cucuteni-Trypillian culture in Ukraine. Retracing the matrilineal genealogy of Nicholas II leads to Elizabeth of Luxembourg (1409-1442), Queen of Germany, Hungary and Bohemia, and daughter of Holy Roman Emperor Sigismund. (2010). Your email address will not be published. Sokolov, A.S., Nedoluzhko, A.V., Boulygina, E.S., Tsygankova, S.V., Sharko, F.S., Gruzdeva, N.M., Shishlov, A.V., Kolpakova, A.V., Rezepkin, A.D., Skryabin, K.G. Pala et al. Phylotree.org is the maternal (mtDNA) tree of humanity. (2007) and Kofler et al. Highest frequencies more prevalent in North Italians … Haplogroup T2b is a branch on the maternal tree of human kind. The phylogeny of haplogroup T2 being so complex, in particular downstream of T2b, higher resolution tests are required to identify which deep clades could be of Indo-European origins. T2b is the most common T2 subgroup found in Europe today and it has been identified in ancient samples from the LBK in central Europe. (2014) tested mtDNA samples from the Yamna culture, the presumed homeland (or Urheimat) of Proto-Indo-European speakers, and found T2a1b in the Middle Volga region and Bulgaria, and T1a both in central Ukraine and the Middle Volga. Haplogroup is the term scientists use to describe a group of mitochondrial or Y-chromosome sequences that are more closely related to one another than to other sequences. Each build is a major update to the tree. Coble, M.D., Just,R.S., O'Callaghan, J.E., Letmanyi, I.H., Peterson,C.T., Irwin,J.A. It is the best evidence so far that haplogroup T was present in Europe before the continent was recolonised by Neolithic farmers. It serves as the main repository for mtDNA full sequence profiles. Subclades and Coding Region results Are these results T2b? Jesse James. Note: This information does not imply an endorsement of YFull or their methods. Nevertheless, Lazaridis et al. I haplogroup is found in Scandinavia and Croatia with some in the Middle East, which most likely is the source. The drying out of the Sahara from around 6,000 years ago and the associated ‘Bantu expansion’, one of the largest migrations in human history, saw E1b1a’s dispersal to Central Africa, East Africa, Southern Africa and, to a lesser ex… (2007). Dr. David Pike is the administrator of the haplogroup T mtDNA project and the mtDNA T2 project at Family Tree DNA. The frequency of T1a and T2 in Yamna samples were each 14.5%, a percentage higher than in any country today and only found in similarly high frequencies among the Udmurts of the Volga-Ural region. T2* is essentially a West Eurasian haplogroup. (2015) and among them were two T2b lineages, which would indicate at first sight that T2b was already present among Near Eastern farmers before they entered Europe. Elsewhere in Europe, this line is around 6 percent of the population in Germany and around 5 percent of the population in the British Isles, France, and the Netherlands. Cardoso, S., Valverde, L., Alfonso-Sánchez, M.A., Palencia-Madrid, L., Elcoroaristizabal, X., Algorta, J., Catarino, S., Arteta, D., Herrera, R.J., Zarrabeitia, M.T. The only subclades found in Bronze Age Indo-European cultures that have not (yet?) Within these areas, the frequency is in about 50% of the population. A study conducted by Castro et al. Ivanov et al. There is another definition of T2 based on complete sequences. (2009) both found that coronary artery disease was significantly more prevalent among patients belonging to haplogroup T. The common C150T mutation has been found at strikingly higher frequency among Chinese and Italian centenarians and may be advantageous for longevity and resistance to stress according to Chen et al. (2007) and González et al.
