DMXX recently mentioned this. Anybody have any info on frequency, subclades and origin of this y J? I recall lots of Neolithic mtdna lineeages there too. Could the Quijja or Ordos culture be implicated? I would figure the pre IE and Altaic inhabitants would have belonged to y Q , be east+west euarsians admixed and have spoken extinct languages as the Mongolian Altai and Hami cemetery results were indicating.

Another case that I know of is of a Oghuz Turkic Tribe, at 12 STRs he is 1gd from me, but now he is placed under J1-L862 subclade, his ancestors are from NW of China. So I think there is some J1 there, and may be J1-Z1828 and J2 also.

Here, have a data dump (I don't know much of anything about J):

Turko-Mongolic minorities in NW China - 0.6% J(xJ2) and 1.7% J2 in Qinghai + Gansu (of 179 men); 1.5% J(xJ2) and 10.6% J2 in Xinjiang (of 274 men).

Gansu Han Chinese - 1% (2/221) J2a*-M410(xJ2a1a-M322, J2a1b-M67, J2a1d-M319, J2a1h1-M158)

Uyghurs from Xinjiang - 14% (27/187) - 1/187 J*, 1/187 J1, 1/187 J2a1b, 20/187 J2a* (as above), 3/187 J2b*(xJ2b1-M205, J2b2-M241), 1/187 J2b2

Ningxia Hui (NW Chinese Muslims) 13% (8/62) J - 1/62 J1, 2/62 J2a1b, 5/62 J2a*

Mongolians - 4% J (7/160) - 2/160 J1a2b-Page8, 2/160 J2a*(xJ2a1-Page55), 1/160 J2a1*(xJ2a1a, J2a1b, J2a1h), 1/160 J2a1b*(xJ2a1b-M92), 1/160 J2a1h-M530

Generally J is found at low to very low frequencies across northern China, Tibet, and Siberia. Seems like rather a mixed bag of subclades.
