ABSTRACT
<p><b>OBJECTIVE</b>To investigate the alleles and genotypes frequency of 10 short tandem repeat (STR) loci (DXS101, DXS6789, DXS6799, DXS6804, DXS7130, DXS7132, DXS7133, DXS7423, HPRTB, DXS8378) on X chromosome of Chinese Hui nationality population.</p><p><b>METHODS</b>The study of 10 STR loci was performed by using the techniques of PCR, polyacylamide gel electrophoresis and silver staining.</p><p><b>RESULTS</b>Among unrelated Hui individuals, the allele numbers of 10 STR loci DXS101, DXS6789, DXS6799, DXS6804, DXS7130, DXS7132, DXS7133, DXS7423, HPRTB, DXS8378 were 9, 8, 4, 6, 6, 6, 4, 4, 5 or 5 respectively; the numbers of genotypes were 17, 22, 7, 14, 14, 15, 6, 7, 12 or 8 respectively. The distribution of genotypes from these 10 STR systems fitted the Hardy-Weinberg equilibrium (P> 0.05). Polymorphisms information content of 10 STR loci, except for DXS7133 (0.48) and DXS7423 (0.48), ranged from 0.54 (DXS6799) to 0.80 (DXS6789); the power of discrimination were from 0.89 (DXS7133, DXS7423) to 0.99 (DXS6789, DXS7132, DXS101).</p><p><b>CONCLUSION</b>The loci of 10 STR on chromosome X are appropriate for individual identification, paternity testing involving a female child and for study on related disease.</p>
