摘　　要：Insertion/deletion polymorphisms(InDels)have been treated as a prospective and helpful genetic marker in the fields of forensic human identification,anthropology and population genetics for the past few years.In this study,we developed a six-dye multiplex typing system consisting of 34 autosomal InDels and Amelogenin for forensic application.The contained InDels were specifically selected for Chinese population with the MAF≥0.25 in East Asia,which do not overlap with the markers of Investigator^(■)DIPplex kit.The typing system was named as GoldeneyeTM DNA ID System 35InDel Kit,and a series of developmental validation studies including repeatability/reproducibility,concordance,accuracy,sensitivity,stability,species specificity and population genetics were conducted on this kit.We confirmed that the 35InDel kit is precise,sensitive,species specific and robust for forensic practice.Moreover,the 35InDel kit is capable of typing DNA extracted from forensic routine case-type samples as well as degraded samples and mixture samples.All markers are proved to be highly polymorphic with an average observed heterozygosity(He)of 0.4582.The combined power of discrimination(CPD)is 0.999999999999978 and the combined power of exclusion in duos(CPE_(D))and trios(CPE_(T))are 0.978837 and 0.999573,respectively,which are higher than those of the Investigator^(■)DIPplex kit.Thus,the GoldeneyeTM DNA ID System 35InDel kit is suitable for forensic human identification and could serve as a supplementary typing system for paternity testing.
