摘　　要：为研究姓氏群体Y染色体特异STR单倍型的遗传多态性,采用PCR复合扩增和ABI PrismTM3100基因测序仪荧光检测方法对DYS426等9个Y-STR基因座进行基因分型,检测深圳地区李姓无关男性个体血样139份、王姓无关男性个体118份、张姓无关男性个体119份。结果在139份李姓群体中,共检出126种单倍型,其中118种单倍型仅出现1次,检出频率最高的1种单倍型出现6次,单倍型多样性为0.9974;118份王姓无关男性样本中,共检出105种单倍型,其中94种单倍型仅出现1次,检出频率最高的1种单倍型出现4次,单倍型多样性为0.9953;张姓无关男性样本中,共检出101种单倍型,其中88种单倍型仅出现1次,检出频率最高的1种单倍型出现4次,单倍型多样性为0.9964。结果表明:深圳地区李、王、张姓氏无关男性个体Y-STR单倍型的遗传多态性丰富,与以往的汉族无关男性群体遗传资料相比较,差异不显著。To study the genetic polymorphisms of Y-chromosome-specific STR loci in Chinese of different surnames, 9 Y-STR loci were amplified by single fluorescent multiplex PCR and the PCR products were detected by using ABI Prism^TM 3100 DNA Sequencer. Samples were randomly-selected from male blood donors in ShenZhen. These individuals, who were otherwise unrelated, had the most common surnames among Chinese as their surnames, namely Li, Wang or Zhang. There were 139 subjects with surname Li, 118 with surname Wang and 119 with the surname Zhang. In the Li population, a total of 126 haplotypes was found and 118 of them were unique, with a haplotype diversity 0.9974. In the Wang population, a total of 105 haplotypes was found and 94 of them were unique, with a haplotype diversity of 0.9953. In the Zhang population, a total of 101 haplotypes was found and 88 of them were unique, with a haplotype diversity of 0.9964. Our results indicated that the genetic polymorphisms of Y-STR haplotypes at these 9 loci in unrelated male individuals with Chinese surnames of Li, Wang or Zhang are highly polymorphic and showed no significant differences with our previous data of haplotype polymorphisms in unrelated male individuals from the Chinese ethnic Han population.
