I have tested myself on 23andme and later on ftdna. I knew i was +/- 15 east/central asian before ftdna published my results. According to ftdna there was no such thing as east asian populations. You can say my euro/indian pop is highly siberian/east asian shifted. This is the updated version:

Btw, i didnt say sycthians were turkic in origin, i dont think they were slav either. I'm just saying turks/turkics have absorbed sycithian blood. More than dark skinned, unibrowed, long faced shia's who call themself persian those days.
Btw, sogdians have assimilated in turkish gene pool before the seljuks even entered anatolia.
