title: [Genetic polymorphism of DXS7423, DXS7424, DXS7132, DXS7133, DXS6804 loci on X-chromosome in Ewenke population].
abstract: OBJECTIVE
  To study the genetic polymorphism of five STR loci on X-chromosome in 98 Ewenke population of China and establish the related genetic database.
  
  
  METHODS
  The sequence variation of DXS7423, DXS7424, DXS7132, DXS7133, DXS6804 loci on X-chromosome were analyzed by PCR following PAG electrophoresis and silver staining.
  
  
  RESULTS
  The genetic data of the 5 X-chromosome STRs in Ewenke ethnic group of China is in accordance with Hard-Weinberg equilibrium.
  
  
  CONCLUSIONS
  Five X-STR loci could be used in forensic identification and population genetic research.
