[Genetic polymorphism of four X chromosome short temden repeats loci in Hebei Han population].
OBJECTIVE
To investigate the polymorphism of loci DXS6800, DXS6797, GATA172D05, DXS986 four loci in Hebei Han population.


METHODS
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.


RESULTS
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.


CONCLUSIONS
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.
