Genetic variation analysis of 15 autosomal STR loci of AmpFlSTR Sinofiler PCR Amplification Kit in Henan (central China) Han population.

AmpFlSTR Sinofiler PCR Amplification Kit is specially developed for Chinese forensic laboratories, but there are little population-genetic indices about this kit as a whole. This kit contains 15 STR loci: D8S1179, D21S11, D7S820, CSF1PO, D3S1358, D13S317, D16S539, D2S1338, D19S433, vWA, D18S51, D6S1043, D12S391, D5S818 and FGA. In order to evaluate this kit and to get basic population-genetic indices for its use in forensic practice in Chinese Han population, the DNA of 231 unrelated Han individuals from Henan (central China) were typed using the Kit. The most discriminating locus was D6S1043 while the least was D3S1358. The combined match probability was 9.81x10(-19) and the combined power of exclusion was 0.99999974. Statistical analysis of the generated data indicated no departure from expectation of Hardy-Weinberg Equilibrium (HWE) in all loci but D6S1043 and no linkage disequilibrium in all pairs of loci. The observed and expected heterozygosity, power of discrimination, polymorphic information content, the other population-genetic indices were calculated. Copyright 2010 Elsevier Ireland Ltd.
