Well, the other results in that region resemble the Cappadocian Greek-Lebanese/Coastal Arabs. An ancient sample from Malatya found in a cave resembles the Christian Arabs. Seems like Kura_Araxes/Armenian/Pontic shift happened in the region. It was ruled by Assyrians that regin?
This sample resembles South Central Asian samples from the Bactria culture. I don't know much about Mitanni. Seems like the Levant and Central Asia was connected! We found Cappadocian Greek like results in northern India also!
