title: [Genetic polymorphisms of 10 X chromosome STR loci in a Chinese Tibetan population].
abstract: OBJECTIVE
  To investigate the alleles and genotypes frequency of 10 short tandem repeat (STR) loci on the X chromosome(DXS7423, DXS8378, DXS6799, DXS7424, DXS7130, DXS7132, DXS6789, DXS101, DXS6804, DXS7133) of Tibetan individuals living in Xizang Autonomous Region, Southwest China.
  
  
  METHODS
  The 10 X-chromosomal STR loci were analyzed with PCR, followed by polyacylamide gel electrophoresis and silver staining.
  
  
  RESULTS
  Among unrelated Tibetan individuals, the numbers of alleles in the 10 X-STR loci(DXS7423, DXS8378, DXS6799, DXS7424, DXS7130, DXS7132, DXS6789, DXS101, DXS6804, DXS7133) were 5, 5, 5, 9, 7, 7, 11, 9, 5 and 4, respectively. The genotype frequencies in females were in accordance with Hardy-Weinberg equilibrium.
  
  
  CONCLUSIONS
  The 10 X-chromosomal STRs loci are appropriate for individual identification, for paternity testing involving a female child, and for studies on related disease.
