Abstract
X-chromosomal short tandem repeats (X-STRs) loci are used for forensic practice in recent years which play increasingly important roles in some complex kinship cases. In this paper, a total of 1250 samples obtained from 941 Northern Hans Chinese and 309 Uigur were successfully analyzed using a homemade new multiplex polymerase chain reaction (PCR) system which can analyze simultaneously11 X-STR markers including DXS8378, DXS6795, DXS7132, DXS6803, DXS9898, DXS6801, DXS7133, GATA165B12, HPRTB, DXS8377 and DXS7423. A total of 103 alleles for all the loci were observed. Hardy–Weinberg equilibrium tests demonstrated no significant deviation from expected values ( P > 0.05) for all of the 11 X-STR loci. The results show the 11 loci in the multiplex systems may provide high polymorphism information for kinship testing and relationship investigations, and it is useful for forensic analysis for the two nationality populations from China.
