  • Title: [Genetic polymorphism analysis of 6 STR loci on the X chromosome in Xi'an Han population].
    Author: Yu B, Qin QX, Yan JC.
    Journal: Fa Yi Xue Za Zhi; 2005 Aug; 21(3):188-91. PubMed ID: 16259367.
    Abstract:
    OBJECTIVE: To investigate the alleles and genotypes frequency of 6 short tandem repeat (STR) loci (DXS8378, DXS7132, DXS6789, DXS101, HPRTB and DXS7423) on the X chromosome in Han population. METHODS: The six X-chromosome STR loci were analyzed by PCR following polyacylamide gel electrophoresis and silver stain. RESULTS: Among 120 females from Xi'an Han population, the number of alleles in the 6 loci (DXS8378, DXS7132, DXS6789, DXS101, HPRTB and DXS7423) were 5, 6, 11, 10, 8, and 4 respectively; the number of genotypes in the 6 loci were 10, 17, 29, 32, 22, and 7 respectively; Exact tests demonstrated genotype frequencies in females had no departure from Hardy-Weinberg equilibrium. CONCLUSION: The six X-chromosome STR loci are appropriate for individual identification, paternity testing involving a female child and for study on related disease.
