Abstract
From sequence database information we have newly identified three male-specific and polymorphic tetranucleotide STRs, DYS443 (GDB: 10807127), DYS444 (GDB: 10807128) and DYS445 (GDB: 10807129) on the Y chromosome. Analysis of 190 Japanese males revealed 6, 5 and 4 alleles in the DYS443, DYS444 and DYS445 systems, with calculated STR diversities of 0.68, 0.57 and 0.53, respectively. The cumulative haplotype diversity of the five Y-STRs DYS441, DYS442, DYS443, DYS444 and DYS445 was calculated to be 0.95 and therefore application of these STRs may yield very useful information for forensic individualization.Keywords
