А вот этой статьи об ягнобцах (Таджикистан), по-моему, не было (https://onlinelibrary.wiley.com/doi/abs/10.1002/ajpa.23789):

Abstract

Objectives
The Yaghnobis are an ethno‐linguistic minority historically settled along the Yaghnob River in the Upper‐Zarafshan Valley in Tajikistan. They speak a language of Old Sogdian origin, which is the only present‐day witness of the Lingua Franca used along the Silk Road in Late Antiquity. The aim of this study was to reconstruct the genetic history of this community in order to shed light on its isolation and genetic ancestry within the Euro‐Asiatic context.

Materials and Methods
A total of 100 DNA samples were collected in the Yaghnob and Matcha Valleys during several expeditions and their mitochondrial, Y‐chromosome and autosomal genome‐wide variation were compared with that from a large set of modern and ancient Euro‐Asiatic samples.

Results
Findings from uniparental markers highlighted the long‐term isolation of the Yaghnobis. Mitochondrial DNA ancestry traced an ancient link with Middle Eastern populations, whereas Y‐chromosome legacy showed more tight relationships with Central Asians. Admixture, outgroup‐f3, and D‐statistics computed on autosomal variation corroborated Y‐chromosome evidence, pointing respectively to low Anatolian Neolithic and high Steppe ancestry proportions in Yaghnobis, and to their closer affinity with Tajiks than to Iranians.

Discussion
Although the Yaghnobis do not show evident signs of recent admixture, they could be considered a modern proxy for the source of gene flow for many Central Asian and Middle Eastern groups. Accordingly, they seem to retain a peculiar genomic ancestry probably ascribable to an ancient gene pool originally wide spread across a vast area and subsequently reshuffled by distinct demographic events occurred in Middle East and Central Asia.
