Abstract

Background: The Lisu group is a unique minority in Yunnan province. However, there is a lack of Y-STR population data for Chinese Lisu and the genetic structure of the Lisu group and other populations is unclear.

Aim: To provide genetic data for 23 Y-STRs in the Chinese Lisu population from Chuxiong Yi Autonomous Prefecture, as well as to analyse population genetic relationships between Chinese Lisu ethnic minority and other reference groups.

Subjects and methods: 423 unrelated healthy Lisu males were genotyped using the PowerPlex® Y23 system. Forensic parameters were calculated according to the previously published studies. Genetic structure analysis among Chinese Lisu and other populations was conducted using the YHRD's AMOVA tools.

Results: Gene diversity (GD) ranged from 0.2,466 (DYS438) to 0.8,945 (DYS385a/b) among the 23 Y-STR loci. According to haplotype analysis, 323 different haplotypes were obtained, out of which 271 were unique. The haplotype diversity (HD) and discrimination capacity (DC) were 0.9,977 and 0.7,636, respectively. MDS plot indicated that the Chuxiong Lisu group is genetically related to the Yunnan Yi group.

Conclusions: This is the first report on Y-STR population data for the Chinese Lisu population. These data would be valuable for forensic applications.

中国西南部云南省楚雄彝族自治州傈僳族 23 个 Y-STR 位点的遗传多样性。

背景介绍傈僳族是云南省一个独特的少数民族。目的：提供中国楚雄彝族自治州傈僳族人群 23 个 Y-STR 的遗传数据，并分析中国傈僳族与其他参考群体的群体遗传关系。研究对象和方法：使用 PowerPlex® Y23 系统对 423 名无血缘关系的健康傈僳族男性进行基因分型。方法：使用 PowerPlex® Y23 系统对 423 名无血缘关系的健康傈僳族男性进行基因分型，并根据先前发表的研究结果计算法医参数。使用YHRD的AMOVA工具对中国傈僳族和其他人群进行了遗传结构分析：在 23 个 Y-STR 位点中，基因多样性（GD）从 0.2 466（DYS438）到 0.8945（DYS385a/b）不等。根据单倍型分析，得到了 323 个不同的单倍型，其中 271 个是唯一的。单倍型多样性（HD）和分辨能力（DC）分别为 0.9977 和 0.7636。MDS 图显示，楚雄傈僳族与云南彝族有遗传亲缘关系：这是首次报道中国傈僳族的 Y-STR 群体数据。这些数据对法医应用很有价值。
