I would need to see the paper, that reference is insufficient to find it.

That said, yes, I have lots of info on this.

It appears that my BGA analysis computer program, using 23andme data,
is the best out there using publicly available comparison data.
It would be a bit better if so-called "published" data since about a year was not locked up
tight out of reach.

Ashkenazi Jews do indeed test very similar to southern Italians and
Greeks etc. They are easily distinguished from real Mideasteners
and probably Turks, though I don't have enough Turk testees.
However, if somebody is quite unmixed, their ancestors being in
one place for a long time, even the southern Italians and
Greeks can, marginally, be distinguished from the Jews. We are talking
differences of 1-4% here for this latter distinction. The extent
of a negative value for East Asian is particularly significant.
