A genetic study published in the "American Journal of Physical Anthropology" in November 2007 examined of 17 individuals buried at a Murong Xianbei cemetery in Lamadong, Liaoning, China ca. 300 AD. They were determined to be carriers of the maternal haplogroups J1b1, D (three samples), F1a (three samples), M, B, B5b, C (three samples) and G2a. These haplogroups are common among East Asians and some Siberians. The maternal haplogroups of the Murong Xianbei were noticeably different from those of the Huns and Tuoba Xianbei.
