Abstract

BACKGROUND: Nias is an island located off the western coast of Sumatra, Indonesia. Nias is situated above the Eurasian and Indo-Australian subduction zone plates. This makes it prone to earthquakes and tsunamis. Genetic analysis and genetic variation of short tandem repeats (STR) locus are not widely known. These data are valuable for individual identification and paternity testing.

METHODS: Seven STR loci (TPOX, CSF1PO, D3S1358, D8S1179, vWA, D5S818, and TH01) were analyzed using 25 healthy and unrelated persons Nias population. Allele frequency, power of discrimination (PD), expected heterozygosity, and probability of exclusion (PE) were calculated.

RESULTS: We found 40 alleles. The allele with highest frequency was alleles 9 at the TH01 loci. While the lowest frequency were allele 9 at the CSF1PO loci, allele 12 at the TPOX loci, alleles 17 and 18 at the D8S1179 loci, and alleles 16 and 20 at the vWA loci. The highest Expected Heterozygosity, PD, and PE at the D8S1179 loci. The highest number of alleles is also at D8S1179 loci. All loci followed the Hardy–Weinberg equilibrium (p > 0.05). The PD values for all tested loci ranged from 80.6 to 94.5%.

CONCLUSION: We report the allele frequencies and forensic statistical parameters of seven STR loci (TPOX, CSF1PO, D3S1358, D8S1179, vWA, D5S818, and TH01) in the Nias population, which can be used as a forensic database reference for Nias populations.
