The Keriyan people live in an isolated village in the Taklimakan Desert in Xinjiang, Western China. The origin and migration of the Keriyans remains unclear. We studied paternal and maternal genetic variance through typing Y-STR loci and sequencing the complete control region of the mtDNA and compared them with other adjacent populations. Data show that the Keriyan have relatively low genetic diversity on both the paternal and maternal lineages and possess both European and Asian specific haplogroups, indicating Keriyan is an admixture population of West and East. There is a gender-bias in the extent of contribution from Europe vs. Asia to the Keriyan gene pool. Keriyans have more genetic affinity to Uyghurs than to Tibetans. The Keriyan are not the descendants of the Guge Tibetans.
克里雅人生活在中国西部新疆塔克拉玛干沙漠中一个与世隔绝的村庄里。克里雅人的起源和迁徙情况仍不清楚。我们通过对Y染色体短串联重复序列（Y-STR）位点进行分型以及对线粒体DNA（mtDNA）的完整控制区进行测序，研究了父系和母系遗传变异，并将其与其他相邻群体进行了比较。数据显示，克里雅人在父系和母系谱系上的遗传多样性相对较低，同时拥有欧洲和亚洲特有的单倍群，这表明克里雅人是东西方的混合群体。在欧洲和亚洲对克里雅人基因库的贡献程度上存在性别差异。克里雅人与维吾尔族的遗传亲缘关系比与藏族的更近。克里雅人不是古格藏族的后裔。
