Abstract
Rwanda is one of the smallest countries of Africa, where forensic genetic studies are rarely being conducted and very few DNA databases have been developed. Short tandem repeats (STRs) polymorphisms were investigated in 505 unrelated Rwandese by using the HUMDNA TYPING (Yanhuang) Kit. The following STRs were targeted: D3S1358, D13S317, D7S820, D16S539, SE33, D10S1248, D5S818, D21S11, TPOX, D1S1656, D6S1043, D19S433, D22S1045, D8S1179, Penta E, D2S441, D12S391, D2S1338, vWA, Penta D, TH01, D18S51, CSF1PO and FGA. The purpose of this study was to elucidate the genetic diversity and explore the potential of applying these 24 STR in 505 Rwandan population in forensics. A total of 360 alleles, with corresponding allele frequencies in the range from 0.001 to 0.442, were found in the Rwandan population. SE33 presented the highest polymorphism (PIC=0.921) among these 24 loci, whereas D13S317 presented the lowest one (PIC=0.671). No deviation from the Hardy-Weinberg equilibrium was observed for any of the 24 loci. The forensic parameters, including the combined power of discrimination (PD and the combined exclusion power, have demonstrated that this panel of 24 STRs is highly informative and useful for forensic applications such as individuals’ identification and paternity tests. Additionally, the genetic distances between Rwanda population and other 24 published populations were calculated based on 8 overlapping loci with the polygenetic tree revealing significant clusters in the populations associated with their geographic locations and their historical relationship.
