title: MiniY-STR quadruplex systems with short amplicon lengths for analysis of degraded DNA samples.
abstract: Two short amplicon Y-chromosomal short tandem repeat (miniY-STR) quadruplex systems for the eight Y-STR loci DYS522, DYS508, DYS632, DYS556, DYS570, DYS576, DYS504 and DYS540 were devised using newly designed primer sets. Among 224 samples from Japanese population, amplification product lengths detected in these Y-STR loci ranged from 95 to 147bp, while 170 different haplotype were identified (discrimination capacity=0.7589 and haplotype diversity=0.9949). As a result of test on degraded DNA samples using the miniY-STR quadruplex systems, the systems proved to be an quite effective tools for analyzing degraded DNAs. We conclude that analyses of the miniY-STR quadruplex systems in addition to the commercial available Y-STR multiplex kits are highly useful for forensic practices of degraded DNA samples.
