Highlights
- •Free online Y Chromosome Haplotype Reference Database for use in forensic casework.
- •Worldwide repository of over 136,000 9-locus, over 84,000 17-locus, over 25,000 23-locus haplotypes and 15,000 Y SNP profiles from 917 sampling locations in 128 countries.
- •Search using Excel sheets or GeneMapper exports instead of typing.
- •Assessment of haplotype frequencies (observed and estimated).
- •Enhanced interpretation tools like LR-based mixture calculation.
Abstract
After opening the first version of an internet-accessible worldwide reference database
of Y chromosome profiles 14 years ago and six years after the last major relaunch
the new YHRD 4.0 repository and website has been rolled-out. By November 2014 about
136k 9-locus haplotypes, among these 84k 17-locus haplotypes, 25k 23-locus haplotypes
and 15k Y SNP profiles from 917 sampling locations in 128 countries have been submitted
by more than 250 institutes and laboratories. In geographic terms, about 39% of the
YHRD samples are from Europe, 32% from Asia, 16% from South America, 6% from North
America, 4% from Africa and 2% from Oceania/Australia. Worldwide collaboration is
the driving force for the rapid growth of the database and this, in turn, allows the
evaluation and implementation of enhanced interpretation tools (variable frequency
estimators, LR-based mixture and kinship analysis, Y-SNP-based ancestry assessment).
