Recently described Y short tandem repeat (Y-STR) polymorphisms can be analyzed as informative haplotypes, which are useful in the forensic field. In order to include these systems in our forensic routine, sequence analysis was conducted about the 7 kinds of range (the locus) of DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392 and DYS393.DYS391 showed the repetition of unique, simple unit. DYS389 I, DYS389 II, DYS390 and DYS393 showed the repetition that irregularly, 2 kinds of different units, were mixed each other. Furthermore, there was the insertion of a special arrangement in the font or middle of the unit which DYS19 and DYS392 were decide.We have investigated a case of disputed paternity where the alleged father was dead, using data from the surviving children for eight Y-STR loci (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393 and DYS385: two loci). Various alleles for each system (except DYS385) were sequenced. In the eight Y-STRs both the two legitimate children and a further additional child of the deceased putative father carried the same allele. The present study demonstrates the structure of Y-STRs and the power of Y-STR typing as a tool for solving this kind of case.

最近描述的y短串联重复（Y-STR）多态性可以分析为有益的单倍型，这在法医领域很有用。为了将这些系统包括在我们的法医例程中，对Dys19，Dys389 I，Dys389 II，Dys390，Dys391，Dys391，Dys392，Dys392和Dyss393进行了7种范围（位点）进行序列分析。 DYS389 I，DYS389 II，DYS390和DYS393的重复表明，不规则地，两种不同的单位被混合在一起。 Furthermore, there was the insertion of a special arrangement in the font or middle of the unit which DYS19 and DYS392 were decide.We have investigated a case of disputed paternity where the alleged father was dead, using data from the surviving children for eight Y-STR loci (DYS19, DYS389 I, DYS389 II, DYS390, DYS391, DYS392, DYS393 and DYS385：两个基因座）。测序了每个系统的各种等位基因（DYS385除外）。在八个合法的孩子和死者假定父亲的另外一个孩子的八个Y-STR中，都带有同样的等位基因。本研究证明了Y-STR的结构以及Y-STR键入的功能，作为解决此类情况的工具。
