Objective The aim of this study is to determine the frequencies and parameters of 18 short tandem repeat loci of Zhuang national population in Guangxi area. Methods PCR amplification and capillary electrophoresis technologies were employed to determine the genotypes of 18 STR loci (D5S818, D21S11, D7S820, CSF1PO, D2S1338, D3S1358, vWA, D8S1179, D16S539, Penta E, TPOX, TH01, D19S433, D18S51, FGA, D6S1043, D13S317, D12S391) from 223 non-related individuals by the DNATyperTM 19 Kit. Results 196 alleles were identified, with their frequencies ranging from 0.002 to 0.516. The statistical analysis of the 18 STR loci are H (heterozygosity) values among 0.614~0.888, DP (discriminant power) values 0.788~0.978, PIC (polymorphism information content) values 0.56~0.88, and PE (paternity exclusion) values 0.308~0.771, respectively. Conclusions This work can provide basic data for human population genetics and forensic DNA research.
