Forensic validation of a multiplex containing nine STRs--population genetics in northern Poland.
This paper presents the allele frequency distributions for the nine loci (D3S1358, VWA, FGA, D8S1179, D21S11, D18S51, D5S818, D13S317 and D7S820) present in the commercially available Profiler Plus kit. DNA samples of 202 individuals from Northern Poland were amplified in a multiplex reaction with subsequent automatic detection using capillary electrophoresis. All loci met the Hardy-Weinberg equilibrium conditions. The calculated probability of identity was 2.26 x 10(-11) giving an average probability of identity of 1 in 44 billion. Considerable improvement of analysis precision was observed after substituting the GeneScan 500 for the fluorescent ladder 60-400 bp. The influence of DNA concentration on stutter and artefact formation and the ratio of heterozygote alleles was analysed.
