中国朝鲜族人群6个短串联重复序列位点的遗传多态性

背景许多学者对不同国家、地区、民族人群的短串联重复序列多态性进行了研究报道,但朝鲜族人群短串联重复序列位点的多态性如何?目的了解中国朝鲜族人群D16S539,D7S820,D13S317,CSF1PO,TPOX,THO1 6个短串联重复序列位点的遗传多态性分布,获得相应多态位点的群体遗传学数据.设计单一样本观察.单位牡丹江医学院生物教研室和DNA分析检测室.材料收集2001-01/02牡丹江地区无血缘关系的朝鲜族个体100份血样.方法应用聚合酶链反应扩增片段长度多态性分析方法对100名无血缘关系的朝鲜族个体进行样本基因型检测.主要观察指标D16S539,D7S820,D13S317,CSF1PO,TPOX,THO1 6个短串联重复序列位点的样本基因型.结果①D16S539基因座,观察到6个等位基因,18种基因型.②D7S820基因座,观察到7个等位基因,22种基因型.③D13S317基因座,观察到7个等位基因,23种基因型.④CSF1PO基因座,观察到6个等位基因,16种基因型.⑤TPOX基因座,观察到6个等位基因,11种基因型.⑥THO1基因座,观察到5个等位基因,12种基因型.结论6个位点等位片段多态性分布均符合Hardy-Weinberg平衡定律.且具有较高的杂合度,所得到的等位基因频率等数据可以为中国朝鲜族人群遗传学研究提供依据.

Genetic polymorphism of 6 short tandem repeat loci in Chinese korean

BACKGROUND: Many scholars have reported the study of genetic polymorphism of short tandem repeat loci in different countries, areas, and population. But what is the genetic polymorphism of short tandem repeats loci of Chinese Korean is still unknown.OBJECTIVE:To investigate the distribution of the genetic polymorphism of D16S539 D7S820, D13S317, CSF1PO, TPOX and TH01 in Chinese Korean, obtain the crowded genetic data of corresponding polymorphism loci.DESIGN: Single sample observation.SETTING: Staff Room of Biology, Department of Detecting and Analyzing DNA, Mudanjiang Medical College.MATERIALS: Periphoral blood samples from 100 unrelated individuals in Korean of Mudanjiang were chosen from January 2001 to February 2001.METHODS: Genotype detection was performed in one hundred unrelated individuals with polymerase chain reaction amplification fragment length polymorphism analysis.MAIN OUTCOME MEASURES: Sample genotype of D16S539,D7S820, D13S317, CSF1PO, TPOX, THO1 6 short tandem repeat loci.TH01 locus.CONCLUSION: The genotypes distributions of the 6 short tandem repeat (STR) in Chinese Korean met Hardy-Weinberg equilibrium, and have higher heterozygosities. The gene frequency and other data obtained can provide the basis for studying the crowded genetics of Chinese Korean.
