Mitochondrial sequence haplotype in the Japanese population

Phylogenetic classification of Japanese mtDNA assisted by complete mitochondrial DNA sequences

“…Because this type of sequence had not yet been found in the M7a2 haplogroup, we designated it M7a2*, although it may constitute a different lineage in this haplogroup. The M7a2 haplogroup lineages have been found in Japanese [5,10,18,19,25,26], but not in Koreans and Chinese. [9,[14][15][16][17][20][21][22][23][24].…”

“…Therefore, we designated this haplogroup branch D4c1b1a, although this haplogroup cannot be discriminated by only the control region with D4c1b1. The D4c1b1 control region motif is found in 0.95% of Japanese [5,10,18,19,25,26], 0.29% of Korean [14,15,23,24], and 0.15% of Chinese populations [9,16,17,[20][21][22].…”

Identification of Native American Founder mtDNAs Through the Analysis of Complete mtDNA Sequences: Some Caveats

“…The three sequences with this motif that appear in the Korean data of Snäll et al (2002), however, tested positively for the RFLP site +4830 HaeII (recognizing a transition at nt 4833) of haplogroup G. We additionally found the 4833 transition (confirmed by +4831 HhaI) in four mtDNAs from China (Table 2). Because all of these mtDNA sequences that belong to haplogroup G have (near-)matches with sequences sampled in Japan (Horai et al 1996;Imaizumi et al 2002;Koyama et al 2002), Korea (Pfeiffer et al 1998;Lee et al 1997Lee et al , 2002, and China (Tsai et al 2001;Yao et al 2000Yao et al , 2003a, it appears that these sequences also belong to haplogroup G. The vast majority of these HVS-I and HVS-II sequences share the 150 polymorphism. In particular, eleven HVS-I and HVS-II sequences from the Korean sample of Lee et al (1997) carry the partial motif 16223-16325; seven of them have the additional part 16362-150 of the motif, Yao et al (2003a) and the data underlying figure 1 of Mishmar et al (2003), respectively; 2 n.d. = not determined.…”

Admixture, migrations, and dispersals in Central Asia: evidence from maternal DNA lineages

“…In order to compare the present results with other populations, HVRI data from several European, Middle Eastern, Indian, Central Asian, and East Asian populations were taken from the literature: Kazaks, 3 Kyrgyz, 3 Uighurs, 3 , Altaics, 21 Mongolians, 22,23 Daur, 23 Oroqen, 23 Turks, 24 -26 Han Chinese, 17,27 Han Taiwanese, 28 Ainu, 28 Koreans, 23,28,29 Japanese, 28,30 Europeans, 31 Middle Easterns, 31 Caucasus populations, 32,33 Thai, 34 Indians, 35 Russians, 36,37 Ukrainians, 37 and Siberians. 23,38,39 The networks relating HVRI sequences within some of the haplogroups described were constructed by using a reduced-median algorithm 40 as implemented in the Network 3.0 program.…”
