Mutations at 17 STR loci in Chinese population

Knowledge about mutation rates and the mutational process of short-tandem-repeat (STR) or microsatellite loci used in forensic analysis is crucial for the correct interpretation of resulting genetic profiles. We analysed a total of 19,754 samples from 6532 paternity testing cases at 17 STR loci which are commonly applied to forensics. The parenthood in each of these cases was highly validated (probability>99.99%). We identified 178 mutations. Locus-specific mutation rate estimates varied between 7.0 x 10(-5) and 2.2 x 10(-3), and the overall average mutation rate estimate was 8.4 x 10(-4). The observed mutational features for STRs have important consequences for forensic application such as the definition of criterions for exclusion in paternity testing and the interpretation of DNA profiles in identification analysis. In order to enrich the reference data of STRs mutations which are valuable for forensic application, we suggest the establishment of such database and ask the whole forensic community for data contribution including China.

Belarusian population genetic database for 15 autosomal STR loci

Allele frequencies of 15 short tandem repeat loci included in the AmpFlSTR Identifiler kit (Applied Biosystems) were obtained from a sample set of unrelated individuals living in Belarus (n=176). For all loci, no deviation from Hardy-Weinberg equilibrium was found. Results were compared with data available for the Belarusian minority residing in northeastern Poland and for other Slavic populations. Statistically significant differences were observed between Belarusians and all compared populations. The values of heterozygosity, polymorphic information content (PIC), power of discrimination (PD), power of exclusion (PE), paternity index (PI) and matching probability (pM) were calculated.
