The Y Chromosome Haplotype Reference Database ( YHRD ) is an open-access, annotated collection of population samples typed for Y chromosomal sequence variants. Two important objectives are pursued: (1) the generation of reliable frequency estimates for Y-STR haplotypes and Y-SNP haplotypes to be used in the quantitative assessment of matches in forensic and kinship cases and (2) the characterization of male lineages to draw conclusions about the origins and history of human populations. The database is endorsed by the International Society for Forensic Genetics (ISFG) . By May 2023 about 350,000 Y chromosomes typed for 9-29 STR loci have been directly submitted by worldwide forensic institutions and universities. In geographic terms, about 53% of the YHRD samples stem from Asia, 21% from Europe, 12% from North America, 10% from Latin America, 3% from Africa, 0.8% from Oceania/Australia and 0.2% from the Arctic. The 1.406 individual sampling projects are described in more than 800 peer-reviewed publications

73-631: YHRD is built by direct submissions of population data from individual laboratories. Upon receipt of a submission, the YHRD staff examines the originality, relevance, plausibility and validity of the data and assigns an accession number to the population sample if these criteria are met. The submissions are then registered to the public database, where the entries can be filtered for haplotypes, contributors or accession numbers. All population data published in forensic journals as FSI: Genetics or International Journal of Legal Medicine are required to be validated by

146-579: A recordable offence must submit a DNA sample, the profile of which is then stored on the DNA database. Those not charged or not found guilty have their DNA data deleted within a specified period of time. In Scotland, the law similarly requires the DNA profiles of most people who are acquitted be removed from the database. New Zealand was the second country to set up a DNA database. In 2019 The New Zealand DNA Profile Databank held 40,000 DNA profiles and 200,000 samples. The United States national DNA database

219-413: A DNA match made without the use of a DNA database. Research shows that DNA databases of criminal offenders reduce crime rates. A forensic database is a centralized DNA database for storing DNA profiles of individuals that enables searching and comparing of DNA samples collected from a crime scene against stored profiles. The most important function of the forensic database is to produce matches between

It collects an individual's DNA which can reflect their medical records and lifestyle details. Through recording DNA profiles, scientists may find out the interactions between the genetic environment and occurrence of certain diseases (such as cardiovascular disease or cancer), and thus finding some new drugs or effective treatments in controlling these diseases. It

Some people are afraid that their personal DNA information will be let out easily, others may define their DNA profiles recording in the Databases as a sense of "criminal", and being falsely accused in a crime can lead to having a "criminal" record for the rest of their lives. Analysis of molecular variance Analysis of molecular variance ( AMOVA ),

438-581: A further subdivision of the "Eurasian – European Metapopulation" was implemented solely on basis of Y-STR haplotypes . The analysis of ~12,000 European Haplotypes by AMOVA demonstrates that three larger pools of European haplotypes exist: the western, eastern and southeastern metapopulations. Currently the YHRD has seven non-overlapping broadly defined metapopulations: African, Afro-Asiatic, Native American, Australian Aboriginal, East Asian, Eskimo-Aleut, and Eurasian. Some of these metapopulations are further subdivided, e.g. Eurasian into six subcategories, from which

730-400: A private company owning public DNA data has raised concerns, with an Irish Times editorial stating: "To date, Ireland seems to have adopted an entirely commercial approach to genomic medicine. This approach places at risk the free availability of genomic data for scientific research that could benefit patients." The paper's editorial pointed out that this is in stark contrast to the approach

803-778: A separate genetic genealogy database needs to be created that stores DNA profiles of genealogical DNA test results. GenBank is a public genetic genealogy database that stores genome sequences submitted by many genetic genealogists. Until now, GenBank has contained large number of DNA sequences gained from more than 140,000 registered organizations, and is updated every day to ensure a uniform and comprehensive collection of sequence information. These databases are mainly obtained from individual laboratories or large-scale sequencing projects. The files stored in GenBank are divided into different groups, such as BCT (bacterial), VRL (viruses), PRI (primates)...etc. People can access GenBank from NCBI's retrieval system, and then use “BLAST” function to identify

This statistics -related article

1314-508: Is generally measured in compression ratio. The greater the compression ratio, the better the efficiency of an algorithm. At the same time, the speed of compression and decompression are also considered for evaluation. DNA sequences contain palindromic repetitions of A, C, T, G. Compression of these sequences involve locating and encoding these repetitions and decoding them during decompression. Some approaches used to encode and decode are: The compression algorithms listed below may use one of

The program shows the references for the selected population studies which facilitates the correct citation. The tool can be applied for forensic cases when a mixed trace (2 or more male contributors) should be analyzed. The result will be a likelihood ratio of donorship vs. non-donorship of the putative contributor to

1460-513: Is often collaborated with the National Health Service. A national DNA database is a DNA database maintained by the government for storing DNA profiles of its population. Each DNA profile based on PCR uses STR (Short Tandem Repeats) analysis. They are generally used for forensic purposes, including searching and matching DNA profiles of potential criminal suspects. In 2009 Interpol reported 54 police national DNA databases in

1533-534: Is reasonably available. The Australian national DNA database is called the National Criminal Investigation DNA Database (NCIDD). By July 2018, it contained 837,000+ DNA profiles. The database used nine STR loci and a sex gene for analysis, and this was increased to 18 core markers in 2013. NCIDD combines all forensic data, including DNA profiles, advanced bio-metrics or cold cases. The Canadian national DNA database

In forensic casework the probability of a match which is based on the profile frequency is evaluated using different methods. Some of these are recommended by national guidelines, e.g. the augmented counting method with confidence intervals and/or theta subpopulation correction (SWGDAM Interpretation Guidelines for Y-Chromosome STR typing by Forensic Laboratories in

3431-534: The enormous size of each DNA sequence . Every year DNA databases grow exponentially. This poses a major challenge to the storage, data transfer, retrieval and search of these databases. To address these challenges DNA databases are compressed to save storage space and bandwidth during the data transfers. They are decompressed during search and retrieval. Various compression algorithms are used to compress and decompress. The efficiency of any compression algorithm depends how well and fast it compresses and decompresses, which

Majority of the National DNA databases are used for forensic purposes. The Interpol DNA database is used in criminal investigations. Interpol maintains an automated DNA database called DNA Gateway that contains DNA profiles submitted by member countries collected from crime scenes, missing persons, and unidentified bodies. The DNA Gateway

4891-533: The term metapopulation is used in forensic genetics to describe a set of geographically dispersed populations with shared ancestry and continuing geneflow. Thus, the population groups are more similar within the metapopulation than to groups outside the metapopulation. The concept of pooling data to build "national databases" has a very straightforward explanation: law enforcement agencies and forensic services rely on their national population to build reference databases . In most instances offenders and victims stem from

4964-414: The trace. The tool can be applied for kinship cases when a relationship between upstream and downstream relatives (e.g. father-son or grandfather-grandson) should be analyzed. The result will be a likelihood ratio (or kinship index) of patrilineal relationship vs. patrilineal non-relationship of the analyzed persons. Searching the YHRD will result in a match or a non-match between a searched haplotype and
