OBJECTIVETo establish a nine X-chromosome short tandem repeats (X-STR) loci multiplex PCR method and study the polymorphism of the 9 X-STR loci,and to determine its application in kinship tests for forensic medicine.
METHODSA fluorescent multiplex PCR that simultaneously amplifies 9 X-STR loci, i.e. DXS7133, DXS981, DXS7424, DXS6789, DXS7132, GATA165B12, DXS101, GATA31E08 and DXS10011, were set up. PCR products were analyzed using capillary electrophoresis and ABI prism 3100 Genetic Analyzer with GeneMapper ID 3.1 analysis software.
RESULTSWhen 251 unrelated male and 112 unrelated female individuals from southern China were tested, 111 alleles were detected. The power of discrimination in females was 0.5837-0.9959. Mean exclusion chance for X-STR in standard trios with daughters was 0.4072-0.9511. Polymorphism information content was 0.4481-0.9531.
CONCLUSIONThe results demonstrate that the 9 loci in the multiplex system provide high polymorphism information, and the multiplex system provides a fast technology for forensic identification and paternity testing. The X-STR multiplex system can complement the analysis of AS-STR and Y-STR efficiently.

Methods 644 random individuals were paired to con-struct 207046 fictitious duo families. Cases of non-exclusion or with only one exclusionarylocus were count-ed. Results 27 cases could not be excluded by the 15 STR loci. The combined probability of exclusion was 0.999869. Number of cases showing only one exclusionary locus was 384 (0.185%). Conclusion To con-firm relationship in duo cases with only 15 STRs should be careful. Extensive genetic markers is needed to discriminate one locus exclusion or mutation.

Methods The DXS6854 locus was analyzed by PCR following polyacrylamide gel electrophoresis and silver staining. Results Among 189 females and 230 males from Guangdong Han population, 8 alleles were observed with frequencies ranging from 0.0026 to 0.4522. Exact tests demonstrated genotype frequencies in females had no departure from Hardy- Weinberg equilibrium. The discrimination powers for female and male original samples were 0.8633 and 0.7012, respectively. When both mother and her daughter were tested, the probability of excluding a random man as a father was 0.6712. Conclusion The DXS6854 locus is appropriate for individual identification and paternity testing involving a female child.

		                        			To investigate haplotype distribution of the Y-chromosome STRs (DYS19, DYS390 and DYS389 locus) in Han population in Guangdong area. The STRs were typed by poplymerase chain reaction followed by discontinuous PAGE system. Among 130 unrelated males, 81 different haplotypes were observed, 52 out of them were found only one time. The haplotype genetic diversity, discrimination power and non-father exclusion chance are 0. 9989, 0. 9824, 0. 9824, respectively. The high informative haplotypes make these STRs useful for the forensic individual identification and paternity testing.
