STR DNA DATABASE

Autosomal STR DNA Database

Worldwide genetic databases are useful tools in forensic genetics, given that any individual profile must be compared against a population dataset. Some recent catastrophes called the attention to the inexistence of an easy-available worldwide autosomal database, for evaluation of the multiethnic genetic profiles.

The present database collects published data in the main forensic international journals for autosomal Short Tandem Repeats (STRs), at a worldwide scale. Publications reporting at least six of the most used markers were included. The STRs considered were: CSF1PO, D2S1338, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D19S433, D21S11, FGA, Penta D, Penta E, TH01, TPO and vWA. We developed a user-friendly web interface, with geographical disclosure on a Googlemap, so that users can easily identify which populations are already surveyed in different worldwide regions.
The allelic frequencies for each sample will be displayed in an excel file, easily exportable for further comparisons. The broad geographical scale aimed in this database will for sure contribute new insights on general STRs informative power and on population genetics analyses.
The database will have the obvious limitation of not performing a quality control of data, relying on the acceptance criteria used by the main forensic international journals.

In the near future we intend to implement a calculation of match probabilities of DNA profiles.
