A focused population profile of Syriac Orthodox Assyrians from Tur Abdin, their southeastern Turkish and northern Mesopotamian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Tur Abdin Syriac Orthodox Assyrians are a historic Aramaic-speaking Christian population of southeastern Turkey, especially the Tur Abdin plateau around Mardin and Midyat, one of the most important Syriac Christian heartlands.
Turoyo Neo-Aramaic and Classical Syriac are central to community identity, while Turkish, Arabic, Kurdish, and diaspora languages are also common. Many families today live in Turkey, Syria, Lebanon, Europe, the Americas, and Australia.
As a genetic reference, Assyrian Syriac Orthodox Turkey Tur Abdin is useful for comparison with Chaldean Catholic Assyrian Iraq, Assyrian Syriac Orthodox/Catholic Iraq, Armenian Urfa, Armenian Lebanon, Assyrian Turkey Hakkari, Assyrian Iraq, Armenian Sasun, and Armenian Aintab.
In the World Genetics modern G25 comparison, Assyrian Syriac Orthodox Turkey Tur Abdin is closest to Assyrian Chaldean Catholic Iraq, Assyrian Syriac Orthodox/Catholic Iraq, Armenian Urfa, Armenian Lebanon, Assyrian Turkey Hakkari, Assyrian Iraq, Armenian Sasun, Armenian Aintab, Armenian Sebastia, and Armenian Kessab.
