[Forensic Investigation of Goldeneye™ DNA ID 22NC Kit]

To investigate the genetic data of 21 autosomal STR included in Goldeneye™ DNA ID 22NC Kit in Chinese Han nationality and to evaluate the forensic application.

By detected 500 unrelated healthy individuals in Chinese Han nationality of East China with Goldeneye™ DNA ID 22NC Kit, allele frequencies, population genetics parameters and linkage disequilibrium information of the 21 autosomal STR were statistically analyzed.

In the 21 autosomal STR, no deviations from Hardy-Weinberg equilibrium were detected and all loci were independent form each other. DP values of 21 autosomal STR were all above 0.85, and the combined discrimination power was 1-3.616 5 x 10(-26). Combined mean exclusion chance of this system in duo cases was 1-2.786 81 x10(-6), in trio cases was 1-8.545 82 x 10(-1).

Twenty-one autosomal STR included in Goldeneye™ DNA ID 22NC Kit are highly polymorphic in the Han nationality. Combined with Goldeneye™ DNA ID 20A Kit, the kit can satisfy the needs for full-sibling testing and facilitate the solution of this kind of case tools.
