[Genetic polymorphism of 19 STR loci in Xinjiang Barkol Kazakh population].

OBJECTIVE: To investigate 19 short tandem repeat (STR) loci in Chinese Kazakh population in Barkol County with Goldeneye™20A multiplex amplification system. METHODS: DNA samples were screened from 81 unrelated individuals. The 19 loci were D8S1179, D21S11, CSF1PO, D3S1358, D7S820, TH01, D13S317, D2S1338, D18S51, D16S539, TPOX, vWA, D19S433, D5S818, PentaD, PentaE, D6S1043, D12S391 and FGA. The PCR products were analyzed and genotyped by ABI3130XL sequencer. RESULTS: These loci were highly polymorphic. The combined power of discrimination was 0.999999999 and the combined paternity of exclusion was 0.999998914. CONCLUSION: Goldeneye™20A multiplex amplification system is very useful in forensic case investigation for Barkol Kazakh population.
