In human mitochondrial genetics, Haplogroup Z is a human mitochondrial DNA (mtDNA) haplogroup.
Haplogroup Z is believed to have arisen in Central Asia, and is a descendant of haplogroup CZ.
The greatest clade diversity of haplogroup Z is found in East Asia and Central Asia. However, its greatest frequency appears in some peoples of Russia, such as Evens from Kamchatka (8/39 Z1a2a, 3/39 Z1a3, 11/39 = 28.2% Z total) and from Berezovka, Srednekolymsky District, Sakha Republic (3/15 Z1a3, 1/15 Z1a2a, 4/15 = 26.7% Z total), and among the Saami people of northern Scandinavia. With the exception of three Khakasses who belong to Z4, [5] two Yakut who belong to Z3a1, [5] two Yakut, a Yakutian Evenk, a Buryat, and an Altai Kizhi who belong to Z3(xZ3a, Z3c), [5] and the presence of the Z3c clade among populations of Altai Republic, [5] nearly all members of haplogroup Z in North Asia and Europe belong to subclades of Z1. The TMRCA of Z1 is 20,400 [95% CI 7,400 <-> 34,000] ybp according to Sukernik et al. 2012, [2] 20,400 [95% CI 7,800 <-> 33,800] ybp according to Fedorova et al. 2013, [5] or 19,600 [95% CI 12,500 <-> 29,300] ybp according to YFull. [3] Among the members (Z1, Z2, Z3, Z4, and Z7) of haplogroup Z, Nepalese populations were characterized by rare clades Z3a1a and Z7, of which Z3a1a was the most frequent sub-clade in Newar, with a frequency of 16.5%. [6] Z3, found in East Asia, North Asia, and MSEA, is the oldest member of haplogroup Z with an estimated age of ~ 25.4 Kya. [6] Haplogroup Z3a1a is also detected in other Nepalese populations, such as Magar (5.4%), Tharu, Kathmandu (mixed population) and Nepali-other (mixed population from Kathmandu and Eastern Nepal). [6] S6). Z3a1a1 detected in Tibet, Myanmar, Nepal, India, Thai-Laos and Vietnam trace their ancestral roots to China with a coalescent age of ~ 8.4 Kya [6]
Fedorova et al. 2013 have reported finding Z* (xZ1a, Z3, Z4) in 1/388 Turks and 1/491 Kazakhs. These individuals should belong to Z1* (elsewhere observed in a Tofalar), Z2 (observed in Japanese), Z7 (observed in the Himalaya), Z5 (observed in Japanese), or basal Z* (observed in a Blang individual in Northern Thailand).
