The study of blood samples extracted directly from healthy people, who is Vietnamese and not relative, lives over the country. PCR technique and denaturing polyacrylamid gel electrophoresis were applied for determination of allele frequencies of D13S317. The primary results showed that allele frequencies of D13S317 locus was polymorphic AND, repetitive sequence unit of 4 nito- base which located on the long hand of chromosome No 13. The locus contained 9 alleles, 242-270 bp. The numbers of repeat units in population were 7, 8, 9, 10, 11, 12, 13, 14, 15. The highest frequency at allele No 8, and allele No 7 had not appear in the observed samples.
