- In Opera, press '+' or '-' to change the size of the text.
What is the frequency of a certain allele in the following populations?
The IPD Database does not store allele frequency data. We recommend the following source of data:
- www.allelefrequencies.net - describes the frequencies of alleles in different populations,
at various polymorphic regions within Histocompatibility and Immunogenetics.
Data may be searched under country, region, ethnic origin.
How should I cite the database?
For citations please use:
IPD-the Immuno Polymorphism DatabaseNucleic Acids Research (2005), 331:D523-526
- Killer-cell Immunoglobulin-like Receptors (KIR) Nomenclature Report, 2002Tissue Antigens (2003) 62:79-86 (Abstract)Immunogenetics (2003) 55:220-226 (Abstract)Human Immunology (2003) 64:648-654 (Abstract)European Journal of Immunogenetics (2003) 30:229-234 (Abstract)Journal of Immunological Methods (2003) 281:1-8
Reports problems with a particular tool
If you having trouble with a specific tool, the alignment tool for instance. Please first see if the solution is listed in the help pages provided, if this does not solve the problem contact IPD Support. The e-mail should list the name of the tool, and all the parameters used. For instance if an alignment failed to work then you should include the values used for the Locus, Specific Sequences, Type, Reference, Display, Formatting and "Cut & Paste". This better enables us to replicate and diagnose the problem.
I want the sequences in this particular format?
Please check the FTP directory before asking for sequences in a particular format. The FTP directory contains copies of the database as FASTA, PIR and MSF formatted files. It also contains EMBL-like flat files and copies of the text versions of the alignments.
I am having trouble with the sequencing software from a particular company?
We cannot advise or support external software. If you are experiencing software trouble when sequencing KIR alleles please contact the support line for that particular make of software.
