Population data of 30 insertion-deletion markers in four Chinese populations

In this study, we assessed 30 insertion-deletion polymorphisms (Indels) (Investigator DIPplex® kit) in four Chinese populations (n = 952) and evaluated their usefulness in forensic genetic applications. After the Bonferroni correction at a 95 % significance level (p = 0.0017), there were no deviations from the Hardy-Weinberg equilibrium observed except for the HLD114 locus in the Tibetan ethnic group studied. A high level of discrimination power was observed for the DIPplex® kit in four sample populations (CDP > 0.9999) and the combined random match probabilities (CMP) were in the range of 1.4766 × 10(-11) to 5.2742 × 10(-13). Four Indels have been selected for further analyses as possible ancestry informative single nucleotide polymorphisms. The study support that the Investigator DIPplex® kit provides a powerful supplement to standard short tandem repeat-based kits for individual identification and kinship analysis in the Chinese population.
