Haplogroup C-F3393

Haplogroup C1 also known as C-F3393, is a major Y-chromosome haplogroup. It is one of two primary branches of the broader Haplogroup C, the other being C2 (also known as C-M217; the former Haplogroup C3).

The basal paragroup, C1* (C-F3393*), has not been found, in samples from living or dead males. Of the two primary branches, C1b is common in parts of Oceania and Asia, whereas C1a is extremely rare worldwide and has been found only amongst individuals native to Japan, Nepal, and Southern Europe.

Distribution

The paragroup C1* (C-F3393*) and its subclades are the predominant Y-DNA haplogroups among peoples indigenous to Australia, some of the Pacific Islands and South Asia. Other subclades are found, at very low frequencies, in isolated locations throughout the Eurasian landmass and adjoining islands.

It is likely that more than 40% of indigenous Australian males belonged to the subclade C1b2b (C-M347) known previously as C4, before contact with European settlers.^[2] Within C-M347 at least two subclades have been identified: C1b2b1 (DYS390.1del,M210) and an as yet unresolved offshoot of the C1b2b1 paragroup (i.e. M347xDYS390.1del,M210).

C1b2a (M38), previously known as C2, is virtually restricted to Island South East Asia, New Guinea, Melanesia, and Polynesia.^[3] Of its subclades, C1b2a1a (P33) is found at a high frequency among Polynesians.^[4][5]

Some minority populations throughout Asia have been found to possess C1b1a (C-B66/Z16458) and C1b1a1 (C-M356) at high levels. C1b1a is found at low frequencies in South Asia, Central Asia, and Southwest Asia.^{[6][7][8][9][10][11]} C1b1a1, previously known as C5, is significant in South Asia.^[3]

One of the most interesting findings of recent genetic surveys is that the sole living members of C1a (CTS11043) are not only rare, but distributed geographically in an extremely bifurcated pattern:

• C1a1 (C-M8) is now found at a low frequency only in Japan.^[3]
• C1a2 (C-V20), known previously as C6 now appears to be found only among Southern European and Nepali males.^[12][13] The 7,000-year-old remains of a hunter-gatherer from La Braña, Asturias, Spain carried it.^[14] However, C1a2 was evidently more widespread in the past: a male from the Great Hungarian Plain, approximately contemporaneous to the La Braña man also carried it,^[3][15] as did the 30,000-year-old remains of a hunter-gatherer from the Pavlov-Dolní Věstonice area (Czech Republic).^[16]
