Genetic polymorphism of four X chromosome short temden repeats loci in Hebei Han population / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the polymorphism of loci DXS6800, DXS6797, GATA172D05, DXS986 four loci in Hebei Han population.</p><p><b>METHODS</b>The genome DNA of unrelated individuals,the families and rotten materials were extracted with phenol-chloroform method and Chelex-100 method,respectively. The PCR products were detected by the polyacrylamide gel electrophoresis and DNA sequencing analysis.</p><p><b>RESULTS</b>Among 150 unrelated males and 150 unrelated females from Hebei Han population, 25 alleles were found in the 4 loci. One hundred and thirty-eight haplotypes of the male were detected. The haplotype diversity reached 0.9986.</p><p><b>CONCLUSION</b>The findings provided the polymorphic data of DXS6800, DXS6797, GATA172D05, and DXS986 loci in Hebei Han population. The four loci are relatively abundant in polymorphic information for identification and the obtained data of Hebei Han population can be applied to the X-STR genetic data bank.</p>

Polymorphism of five short tandem repeat loci on chromosome X in Hebei Han population / 中华医学遗传学杂志

<p><b>OBJECTIVE</b>To investigate the polymorphism of DXS6801, DXS6809, DXS7423, DXS7424, DXS9902 five loci in Hebei Han population.</p><p><b>METHODS</b>The PCR products were detected by the polyacrylamide gel electrophresis and DNA sequencing analysis.</p><p><b>RESULTS</b>Among 114 irrelative males and 118 irrelative females from Hebei Han population, 31 alleles were found in the 5 loci. One hundred and one haplotypes of the male were detected and the haplotype diversity reached 0.9975.</p><p><b>CONCLUSION</b>The five loci are relatively abundant in polymorphic information for identification and paternity test. And the obtained data of Hebei Han population can be applied to the X-short tandem repeat genetic data bank.</p>
