Short tandem repeat (STR) analysis provides genetic fingerprinting of individuals and indispensable technique for forensic human identification. Recently, it is used in social areas like the identification of The Korean war, identification of descendants of national merit, and missing children. STR analysis is accomplished by analyzing 2 to 5 same repeating bases in the human genome, and currently FBI provides the combined DNA Index System (CODIS) based on DNA databases. We analyzed the autosomal short tandem repeat loci D13S317, D16S539, D21S11, and analyzed Amelogenin to identify male or female. The samples were collected unrelated 50 Korean individuals, and 4 STR loci of these samples were analyzed by ABI3130 genetic analyzer. We demonstrated that 47 samples out of 50 were classified completely with only 4 STR loci, and perfect sex identification could be performed with Amelogenin analysis.
