title: [Polymorphisms on 15 STR loci of Han population in Yan'an].
abstract: OBJECTIVE
  To investigate the polymorphisms of 15 STR loci of Han population in Yan'an.
  
  
  METHODS
  Blood samples were obtained from 100 unrelated Han individuals in Yan'an. DNA templates were screened by AmpF/STR Identifiler kit and ABI3100Avant DNA analyzer.
  
  
  RESULTS
  The allele frequencies of 15 STR loci ranged from 0.005 to 0.550, and the genotype frequencies ranged from 0.010 to 0.310. The combined match probability was 2.5x10(-17) and combined EPP was 0.999999999.
  
  
  CONCLUSIONS
  The 15 STR loci used in this study were highly polymorphic in Han population in Yan'an and suitable for population study and forensic cases in this region.
