Study on the STR TPOX in an Italian and an Austrian population using two different primer pairs and three different electrophoretic methods.

ABSTRACT

The short tandem repeat TPOX was studied using two different pairs of primers and three different electrophoretic methods with the aim of optimizing and standardizing the typing conditions for this locus. A genetic population study was subsequently conducted on two population samples from Central Italy (151 individuals) and from Austria (153 individuals) and compared using an R x C contingency table. With the aim of using this system for forensic samples, differences in sensitivity between the methods utilized were studied and several parameters of forensic interest for the two populations (PD, MEC, MEP, pM, PIC) were calculated. A new multiplex system for the loci CSF1PO, TPOX and CD4 is also presented.
