Abstract:
Objective To develop a five fluorescence-labeled multiplex amplification system for 15 loci and study genetic polymorphism in Xinjiang Uygur population. Methods The STR loci were screened. The alleles were named according to the number of repeats by sequencing. The sensitivity, species specificity, identity and stability of the five fluorescence-labeled multiplex amplification system for the 15 loci were all tested. Then, the genetic polymorphism was analyzed in Xinjiang Uygur population and compared with other ethnic groups including Xizang Tibetan, Xiuyan Manchu, and Guangzhou Han pop-ulation. Results The 15 loci multiplex amplification system was established. The sensitivity was 0.3 ng with good species specificity, identity and stability. The distributions of genotype for 13 STR loci in Uygur population were in accordance with Hardy-Weinberg equilibrium with no genetic linkage between these loci. Most loci showed statistically significant among different populations. Conclusion The estab-lished system has application value in forensic evidence. The 13 STR loci in Uygur population have high polymorphisms to be the supplements to the existing loci.
