The IMGT/HLA database

Methods Mol Biol. 2007;409:43-60. doi: 10.1007/978-1-60327-118-9_3.


The human leukocyte antigen (HLA) complex is located within the 6p21.3 region on the short arm of human chromosome 6 and contains more than 220 genes of diverse function. Many of the genes encode proteins of the immune system and include many highly polymorphic HLA genes. The naming of new HLA genes and allele sequences and their quality control is the responsibility of the WHO Nomenclature Committee for Factors of the HLA System. The IMGT/HLA Database acts as the repository for these sequences and is recognized as the primary source of up-to-date and accurate HLA sequences. The IMGT/HLA website provides a number of tools for accessing the database: these include allele reports, sequence alignments, and sequence similarity searches. The website is updated every 3 months with all the new and confirmatory sequences submitted to the WHO Nomenclature Committee. Submission of HLA sequences to the committee is possible through the tools provided by the IMGT/HLA Database.
