Y chromosome STR haplotypes of Tibetan Living Tibet Lassa.

Allele frequencies and haplotypes of the 17 Y-chromosome STRs loci, namely DYS19, DYS385a/b, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635 (YGATA C4), and YGATA H4 were determined in a sample of 131 healthy unrelated males from the Lassa area of Tibet Autonomy Region of China (SW China). In 131 samples 106 different haplotypes were encountered, of which 105 were observed only once. The overall haplotype diversity was 0.9998. The results demonstrate that these loci will be very useful for human identification in forensic cases and paternity tests in the Lassa region.
