Sample Description: This sample was collected from Sibos in Yining in the Xinjiang autonomous region (northwest China). The Sibos, currently residing in Yining, are decendants of approximately 3000 Sibos (1000 Sibo warriors and thier families), who migrated from Shenyang (northeast China) to Yining in 1764 during the Qing dynasty. The Sibos are Tungusic speakers, a language belonging to the Altaic language family. This sample was obtained anonymously through local physicians and with consent of the participants.
