I was looking for studies done on U2b2. Where is it most frequently found and where did it originate? Is it Central/South Asian?

U2b is one of the three sister clades of U2 found all over south asia . I dont know where it originated but currently it is not found in places outside of south asian influence

Not sure of any studies, but here are a bunch of samples from GenBank.

U2b2a is mostly found in India and Tibet, U2b2 is mostly found in India and Pakistan (there is one sample from each group from Punjab), and a few samples from other regions, including Thailand and South Africa, and samples from Sri Lanka and Saudi Arabia. The South African sample is pre-U2b1 (i.e., between U2b and U2b1) and represents a very ancient branch, so it's uncertain where it originated. Possibly a South African person with South Asian ancestry? It would be very helpful to have more U2b full sequence samples. Anyone who tested at 23andMe can also send me their mthap extra mutation list and I'll compare with my database of U2b FMS samples.

hmm. Thanks, I found this link where it was found in Kazakhstan, this made me wonder how did it arrive there?

All the Central Asian stan countries do have some south asian specific mtdna . So it is not much of a surprise

Could be!
You stated earlier "south-Asian" influence with respect to u2b/u2b2, does Kazakstan have significant South-Asian influence?

There was a huge slave market in Uzbekistan in the 1700's where captured Indian slaves were taken, its possible some slaves made their way up to present day Kazakhstan.

That could mean more mtdna(s) likely thought to be of South-Asian origin should show up around there. Someone wrote somewhere u2b2 was pretty frequent in Kazakstan, can't find a legit source. Also, slave market has to do with lower castes! esp. in the 1700's?! wonder about the population where u2b2 within the South-Asian population. I just read an article where u2b2 was found in Kerala Jews. Its common in my maternal ancestral lineage amongst Kandahari Pashtuns, I checked another article where Ghilzis were found with u2b2. Its getting interesting.

U2 was found in kostenki man, in Western Russia. It probably originated east of that region and some subclades(mainly U2b2) went so south and south central Asia either with ANE/WHG-UHG migrations or other steppe migration while other subclades stayed in Europe.

The common types in South Asia are U2a, U2b, and U2c. The common U2 outside South Asia are U2e and U2d and both are related to U2c.

"In the proposed study, the mtDNA HVI and HVII region sequences (354 and 217 bp, respectively) of seven ancient samples collected from Cemialo Sırtı (Batman) excavation site in the southeastern of Anatolia were successfully obtained. The mtDNA HPG compositions of these ancient human samples were determined.*The mtDNA haplogroups of seven ancient individuals were assigned as H1z1, M1a, U2b1, H1a, HV, R2 and R6*and PhyloTreemt (http://www.phylotree.org/) was used for determination of the mtDNA haplogroups. Furthermore the mtDNA HVI - HVII region sequences of seven samples were comparatively analyzed with some modern human populations and various Neolithic populations that were retrieved from databases from Northern Syria (8000 BC), Central Europe (6000-1550 BC) and Southern Paris (5000-4000 BC), including the Sagalassos population which is an ancient Byzantium population (11th–13th century Common Era (CE)) near from Ağlasun/Burdur in the Southwestern Anatolia. This study is the first study where the questions about the human ancient DNA (aDNA) are addressed in the dedicated ancient DNA laboratory of Middle East Technical University (METU), Ankara, Turkey"

We need the FMS results to see if it is an extinct lineage or related to one of the modern populations. I think the tested a few coding region SNPs but I have not checked yet to see if there was anything useful in those results.

U2b2 somehow made it to the Turin shroud.
"the results raise the possibility of an Indian manufacture of the linen cloth ...haplogroups M39, M56, R7 and R8 are typical of the Indian subcontinent, with the latter essentially present only in Eastern India ... the detection of mtDNA haplogroups that are typically from India is somehow unexpected. One obvious possibility is that during the course of centuries, individuals of Indian ancestry came into contact with TS ... one alternative and intriguing possibility is that the linen cloth was weaved in India, as supported perhaps by the original name of TS - Sindon - which appears to derive from Sindia or Sindien, a fabric coming from India.

From Rakhigarhi to the Shroud of Turin - nice!!
"After building a mitochondrial DNA consensus using damage-restricted sequences, we determined that its haplogroup was U2b2, which is absent in whole mitochondrial genomes sequences available from about 400 ancient Central Asians; today, this specific haplogroup is nearly exclusive to South Asia"
