[Genetic polymorphism of 3 STR loci of CSF1PO, TPOX and TH01 in Chinese Sibo population].

Objective: To obtain allele and genotype frequencies and related forensic data of CF1PO, TPOX and TH01 loci in Chinese Xinjiang Sibo population.

Methods: Genomic DNA from peripheral blood mononuclear cells of normal Chinese Xinjing Sibo population was used as template, and CSF1PO, TPOX and TH01 fragments were amplified by PCR. The PCR products were analyzed by 4% denaturing PAGE and detected using silver stain detection.

Results: Nine alleles were found at CSF1PO locus, eight alleles at TPOX locus and eight alleles at TH01 locus in Chinese Sibo population. All the 3 loci complied with Hardy-Weinberg equilibrium. The heterozygosities were 0.9426, 0.8361 and 0.8853, and the polymorphism information contents were 0.8298, 0.7213 and 0.7626 for CSF1PO, TPOX and TH01, respectively.

Conclusion: The data on the alleles frequency of these 3 STR loci might be used for individual identification and paternity identification and for genetic researches in Chinese Sibo population.
