Haplogroup Q-M120

Distribution

The Americas

One of the 1K Genomes samples, HG01944, from Peruvians in Lima, Peru belongs to Q-M120. Q-M120 is the other branch under Q-F746. It is best known as an East Asian branch of Q.

Grugni et al. (2019) found the presence of the Q-pre-M120 lineage, a precursor to Q-M120, among the Tsimshian people in Alaska.

Asia

Q-M120 is present in Eastern Asia and may trace its origin to East Asia. It has been found at low frequency in samples of Han Chinese, Japanese, Dörwöd Kalmyks, Koreans, Mongols, Tibetans, Uygurs, and Vietnamese. It also has been found among Bhutanese, Murut people in Brunei, Tuvans, Nivkhs, Koryaks, Yukaghirs, and Azerbaijanis. Sengupta et al. (2006) reported finding Q-M120 in the HGDP sample of Pakistani Hazaras, but the Bayesian tree in Supplementary Figure 12 of Lippold et al. (2014) suggests that these HGDP Pakistani Hazara individuals more likely should belong to Q-L275, and that three members of the HGDP Naxi sample and one member of the HGDP Han sample should belong to Q-M120 instead. Di Cristofaro et al. (2013) tested the same sample of Pakistani Hazaras and reported that they belonged to the following Y-DNA haplogroups: 1/25 C-PK2/M386(xM407, M532), 9/25 C-M401, 1/25 I-M223, 1/25 J-M530, 2/25 O-M122(xM134), 1/25 Q-M242(xM120, M25, M346, M378), 1/25 Q-M378, 1/25 R-M124, 8/25 R-M478/M73.

According to a 2019 study, Q-M120 can be found in high concentrations in the northern and eastern regions of China. To a lesser extent, it can be found in North Korea, South Korea and northern Philippines.

South Asia

Sharma et al. (2007) found Q-M120 in 1.6% (1/61) of a sample of Gujars from Jammu and Kashmir in India.

West Asia

Q-M120 has been found in 4.2% (1/24) of Baloch people in Sistan and Baluchestan Province.

Europe

Caucasus

Q-M120 was found in western Georgia among Imeretians.

Associated SNPs

Haplogroup Q-M120 is defined by the presence of the M120 Single Nucleotide Polymorphism (SNP) as well as the M265 (AKA N14) SNP.
