RESUMEN
OBJECTIVE@#To investigate the genetic polymorphisms of 19 STR Loci in Shandong Han population in order to provide the genetic data for paternity testing.@*METHODS@#The genotypes of 205 unrelated individuals in Shandong Han population were typed by Goldeneye 20A kit to get the allele frequencies and population genetic parameters of 19 STR loci. Four kits, Identifiler kit, SinoFiler kit, PowerPlex 16 kit, and Goldeneye 20A kit, were compared with each other and used in the analysis of a special paternity test case.@*RESULTS@#The population genetic parameters of 19 STR loci in Shandong Han Population were obtained. The cumulative discrimination power (CDP) and cumulative probability of exclusion (CPE) ranked from high to low were Goldeneye 20A kit, SinoFiler kit, PowerPlex 16 kit and Identifiler kit, respectively. As duo case, the result of the real case showed that Identifiler kit had no excluding loci, and none of the SinoFiler kit, PowerPlex 16 kit or Goldeneye 20A kit could exclude fatherhood.@*CONCLUSION@#Compared with Identifiler kit, SinoFiler kit, and PowerPlex 16 kit, Goldeneye 20A kit shows the higher efficiency than the others, but is not completely satisfied for duo cases.
