The World Health Organization Nomenclature Committee for Factors of the HLA System has adopted changes to the HLA nomenclature system effective April 1, 2010. A detailed description of these changes can be viewed here: http://hla.alleles.org/announcement.html
The IEDB will switch to the new nomenclature in the all interfaces including query reporting, tools and data submissions, by end of March 2011. If you are currently in the process of preparing a data submission to the IEDB that includes HLA restriction data, please plan to complete submissions using the old nomenclature before March 2011.
For more information about the IEDB transition to the updated HLA nomenclature, please contact the IEDB at firstname.lastname@example.org.
