Investigating the genetic characteristics of the Csangos, a traditionally Hungarian speaking ethnic group residing in Romania


Csango people are an East–Central European ethnographic group living mostly in the historical region of Moldavia, Romania. Their traditional language, the Csango is an old Hungarian dialect, which is a severely endangered language due to language shift. Their origin is still disputed among experts and there are many hypotheses since the 19th century. Previous genetic studies found connection with ethnic groups living in Hungary and provided evidence which might support their Hungarian origin. Another study found Inner Asian Altaic ancestry in their genetic makeup. The goal of this study was to analyze the genetic characteristics of the Csango people by comparing their genetic characteristics to contemporary Eurasian populations based on genome-wide autosomal marker data. Our findings suggest that genetic affinity of Csangos to Hungarians is more significant than to Romanians. They also have a detectable connection with Central-Asian and Siberian Turkic ethnic groups. Besides the presumable Middle Eastern/Central-Asian Turkic ancestry, Csangos show ~4% Turkic ancestry from Central Asia/Siberia, which makes them unique in comparison to all other East–Central European populations investigated in this study. The admixture that resulted in this Turkic ancestry could have occurred 30–40 generations ago, which date interval corresponds to Hungarian historical events regarding their migration and the conquest of the Carpathian basin.
