Abstract:
In recent years, a novel multiplex system containing two mini-short tandem repeats, 59 autosomal InDels, two Y-chromosomal InDels, and the Amelogenin gene with all amplicons less than 200 bp has been constructed and validated by ourselves for forensic degration sample, and its forensic application efficiency has been studied in Chinese some populations. Herein, the population genetic polymorphisms of these loci were investigated in Chinese Hui (n = 249) and Mongolian (n = 222) ethnic groups using direct multiplex amplification and capillary electrophoresis platform. The forensic identification efficiencies of this self-developed system were further evaluated in these two groups. And the results showed that the values of the combined power of discrimination were 0.9999999999999999999999999999006 (Hui) and 0.999999999999999999999999999738 (Mongolian), respectively. Moreover, the combined power of exclusion values were 0.99999817 (Hui) and 0.99999779 (Mongolian). The 59 autosomal InDels used in this study exhibited high forensic identification efficiencies in 10 East Asian populations, which was also expected to be a new powerful tool for identifying degraded biological materials in East Asian populations.
