Abstract:
OBJECTIVE:To investigate the genetic data of 12 autosomal STR loci included in Investigator HDplex kit and to evaluate its forensic application in Han nationality of Eastern China.
METHODS:A total of 484 unrelated healthy individuals in Han nationality of Eastern China were investigated with Investigator HDplex kit. Allele frequencies, population genetics parameters and linkage disequilibrium information of the 12 autosomal STR loci were statistically analyzed.
RESULTS:No deviations from Hardy-Weinberg equilibrium were detected and all loci were independent form each other within the studied 484 unrelated healthy individuals. DP values of the 12 autosomal STR loci were all above 0.8, and CDP was 0.999 999 999 92. The cumulative probability of paternity exclusion in duo and in trio were 0.999 82 and 0.999 998 6, respectively.
CONCLUSION:Investigator HDplex kit with 12 highly polymorphic STR loci in Han nationality of Eastern China could be used effectively for forensic DNA genotyping.
