title: [Polymorphism of five short tandem repeat loci on chromosome X in Hebei Han population].
abstract: OBJECTIVE
  To investigate the polymorphism of DXS6801, DXS6809, DXS7423, DXS7424, DXS9902 five loci in Hebei Han population.
  
  
  METHODS
  The PCR products were detected by the polyacrylamide gel electrophresis and DNA sequencing analysis.
  
  
  RESULTS
  Among 114 irrelative males and 118 irrelative females from Hebei Han population, 31 alleles were found in the 5 loci. One hundred and one haplotypes of the male were detected and the haplotype diversity reached 0.9975.
  
  
  CONCLUSIONS
  The five loci are relatively abundant in polymorphic information for identification and paternity test. And the obtained data of Hebei Han population can be applied to the X-short tandem repeat genetic data bank.
