The present study analyses 8 recently described tetranucleotide microsatellites (DYS460, DYS461, GATA-A10, GATA-C4, GATA-H4, DYS434, DYS437, DYS439) in southeast Spain and out of a total of 76 individuals 67 showed different haplotypes. Out of the 67 different haplotypes, 63 were present once, 3 were found 2 times, and 1 was found 7 times (9.21%). By combining the allelic states of the present eight Y-chromosome STRs with those previously carried out on the same individuals, highly informative haplotypes could be obtained. The haplotype diversity using the basic set of Y-STRs (DYS19, DYS389-I, DYS389-II, DYS390, DYS391, DYS392, DYS393, DYS385 and DYX156Y) previously analyzed is 0.9844. For the same individuals, this value using the new set of Y-STRs is slightly lower (0.8949), while the haplotype diversity combining the two sets of primers significantly increase to 0.9868. The results obtained in the present work show the usefulness of these microsatellites for individual identification and paternity testing in forensic genetics.
本研究分析了西班牙东南部最近描述的8个四核苷酸微卫星(DYS460、DYS461、GATA - A10、GATA - C4、GATA - H4、DYS434、DYS437、DYS439),在总共76名个体中,67名显示出不同的单倍型。在这67种不同的单倍型中,63种只出现了一次,3种出现了2次,1种出现了7次(9.21%)。通过将目前这8个Y染色体短串联重复序列的等位基因状态与之前对同一批个体进行检测的结果相结合,可以获得信息量丰富的单倍型。使用之前分析过的基本Y染色体短串联重复序列(DYS19、DYS389 - I、DYS389 - II、DYS390、DYS391、DYS392、DYS393、DYS385和DYX156Y)得出的单倍型多样性为0.9844。对于同一批个体,使用新的Y染色体短串联重复序列得出的该值略低(0.8949),而将两组引物的结果相结合得出的单倍型多样性显著提高到0.9868。本研究获得的结果表明,这些微卫星在法医遗传学的个体识别和亲子鉴定中具有实用性。
