Ashkenazi and North Caucasian connection?

[Figaro]

Not hinting at anything Khazar, so no triggering- but in recent years it’s often said on these forums that there is some Iranic component within Ashkenazim...there’s the Iranic R1a in some, which I believe is lacking in Sephardim (someone correct me..). I’ve also noticed that on certain calls and MTA, my mother (1/16 AJ), out of any non-European pop tends to get Iranic “hits”, and not the expected Minoan or other MENA. (Example, Androvono, and for a long time #2 closest to the presumably Srubnaya Caspian Steppes sample)...

What are thoughts on this? I’m typing on my phone (awaiting for my laptop to be fixed), so pardon my typing...lol..

Note: I know that most North Caucasians are not Iranic speakers, but there is a history there and that would be where AJ’s presumably picked up the component. Also, it is Ossetians who possibly share a common origin with a part of the AJ gene pool.

Bump? Is there real Caucasus ancestry within AJ's?

[Mejgusu]

No I don’t think so, they are basically Levantine+Eastern/Central European. There are Caucasian Jews but they have not any Iranic admixture too and in my knowledge even less European influenced than most of their neighbors. No Caucasian people share any ancestry with Levantine or Jewish groups.

R-Z2122 Levit line - 99.9 % non mixed extreme closed groups of Levits
the upper bound for the age of the M582 clade was estimated as the divergence time of the two Ashkenazi M582
lineages and the Assyrian R1a-Z2122(xM582) sequence, yielding an estimate of 4,000 (SE 300) years
