Y-chromosome STR haplotype profiling in the Mongolian population

Eleven Y-chromosome STR loci (DYS19, DYS388, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, two DYS385 loci and DXYS156Y) were analyzed in 92 randomly chosen males from Mongolia. Allelic frequencies and gene diversity for each Y-STR locus and haplotype diversity were determined to evaluate their usefulness in forensic casework. A total of 84 different haplotypes were identified, among which 77 (83.7%) were individual-specific. The most frequent haplotype surveyed here was found in three individuals (3.6%), of which the ‘minimal haplotype’ (excluding DYS388 and DXYS156Y) was not found in the worldwide Y-STR haplotype reference database (YHRD) available at http://www.yhrd.org.
