IMGT/HLA Database

IMGT/HLA Allele Query Form

The IMGT/HLA Database allows you to retrieve information upon a specific HLA allele as named in the WHO Nomenclature Committee Reports. The report includes previous designations, the EMBL/GenBank/DDBJ accession numbers, references and some information of the source of the allele. Where discrepancies have arisen between reported sequences, the original authors have been contacted where possible, and necessary amendments to published sequences have been incorporated into this alignment. Future sequencing may identify errors in this list and the WHO Nomenclature Committee would welcome any evidence that helps to maintain the accuracy.

The sequence displayed is the virtual sequence used for representing HLA alleles, further details are provided in the nomenclature guidelines

How To Query

To search for an allele entry enter either an allele name (i.e.; A*, A*01, A*01011, and any previous designations) or an EMBL/GenBank/DDBJ accession number (i.e. AJ278305). The search tool will then retrieve all relevant hits. Wildcards will automatically be added to the search, do not add asterisks to accession number queries. A list of null alleles can be retrieved by entering "Locus*N" i.e. ("A*N" for all HLA-A null alleles). More complex queries can be constructed using the SRS browser and the IMGT/HLA flat files.

A full list of all alleles for each locus is available from the following links; Class I list, Class II list, other loci
