[Genetic polymorphisms of 10 X chromosome STR loci in a Chinese Tibetan population]
1The State Key Subject for Forensic Sciences, Key Laboratory of National Ministry of Health for Forensic Sciences, Xi'an Jiaotong University, Xi'an, Shaanxi 710061, P.R.China.
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.
Conclusion:
The 10 X-chromosomal STRs loci are appropriate for individual identification, for paternity testing involving a female child, and for studies on related disease.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...
