The first data of allele frequencies for 23 autosomal STRs in the Ede ethnic group in Vietnam

Abstract

Settled in Vietnam, the Ede ethnic group exhibits unique heritages that belong to the Austronesian-speaking groups. In this study, we genotyped 23 autosomal short tandem repeat (STR) markers in 397 unrelated samples from the Ede population and recorded the first data of allele frequencies and forensic parameters for the Ede. Data analysis revealed high values of the combined discrimination power (0.999 999 999 999 999 999 999 999 950) and the exclusion power (0.999 999 999 999 998). Within the Ede population, D12S391 was indicated to be an informative autosomal STR marker for individual identification and paternity testing. A phylogenetic tree of the Ede and nine other Austronesian groups, spanning from Africa to Asia and Oceania, asserted a close relationship among these groups, especially among the Ede, Malaysian Malay, and Indonesian populations.
