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.

Csango人是东欧-中欧民族志群体，主要生活在罗马尼亚摩尔达维亚的历史地区。他们的传统语言Csango是匈牙利的古老方言，由于语言转换，它是一种濒临灭绝的语言。自19世纪以来，它们的起源仍在专家中引起争议，并且有许多假设。先前的遗传研究发现与居住在匈牙利的种族群体有关，并提供了可能支持其匈牙利血统的证据。另一项研究发现内亚阿尔塔人血统的基因组成。这项研究的目的是通过基于全基因组常染色体标记数据，将Csango人群的遗传特征与当代欧亚人群进行比较，以分析其遗传特征。我们的发现表明，Csangos对匈牙利人的遗传亲和力比对罗马尼亚人的亲和力更重要。他们还与中亚和西伯利亚突厥族群有联系。除了大概的中东/中亚突厥血统外，Csangos还显示中亚/西伯利亚有约4％的突厥血统，与本研究中调查的所有其他东中欧人口相比，它们具有独特性。导致这种突厥血统的混合可能发生在30至40代之前，该日期间隔对应于匈牙利关​​于其迁移和征服喀尔巴阡盆地的历史事件。Csangos显示中亚/西伯利亚有约4％的突厥血统，与本研究中调查的所有其他东中欧人口相比，这使得它们具有独特性。导致这种突厥血统的混合可能发生在30至40代之前，该日期间隔对应于匈牙利关​​于其迁移和征服喀尔巴阡盆地的历史事件。Csangos显示中亚/西伯利亚有约4％的突厥血统，与本研究中调查的所有其他东中欧人口相比，这使得它们具有独特性。导致这种突厥血统的混合可能发生在30至40代之前，该日期间隔对应于匈牙利关​​于其迁移和征服喀尔巴阡盆地的历史事件。
