Forensic genetic value of a 27 Y-STR loci multiplex (Yfiler® Plus kit) in an Italian population sample

The Sardinians were significantly differentiated from the other three Italian groups, thus requiring a specific sub-national Y-STR haplotype database. The Yfiler® Plus kit showed a high power of discrimination which is useful for criminal investigations, principally due to the inclusion of RM Y-STRs.
