Hum Immunol. For more than two decades, international cooperation and information technology have been playing key roles in the identification of suitable unrelated donors and cord blood units for hematopoietic SCT. When these conventions were adopted, it was anticipated that the nomenclature system would accommodate all the HLA alleles likely to be sequenced. Hurley CK, Maiers M, Marsh SG, Oudshoorn M. Tissue Antigens. In case of other allele families in which the number of alleles reaches 100, these will be numbered sequentially; for example, A*24:99 will be followed by A*24:100. NCI CPTC Antibody Characterization Program. The WHO Nomenclature Committee for Factors of the HLA System met during the 15th International Histocompatibility and Immunogenetics Workshop in Buzios, Brazil in September 2008. For allele families that have more than 100 alleles, such as the A*02 and B*15 groups, it will be possible to encode these in a single series. Bone Marrow Transplant. Clipboard, Search History, and several other advanced features are temporarily unavailable. The level of resolution achieved by many of the HLA typing technologies used today does not always allow for a single HLA allele to be unambiguously assigned. The 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. USA.gov.

Nomenclature of HLA Alleles Early in their study, it was recognised that the genes encoding the HLA molecules were highly polymorphic and that there was a need for a systematic nomenclature.

(b) HLA alleles that share identical nucleotide sequences for the exons encoding the peptide-binding domains: HLA alleles that have identical nucleotide sequences for the exons encoding the peptide-binding domains (exons 2 and 3 for HLA class I and exon 2 only for HLA class II alleles) will be designated by an upper case ‘G’, which follows the allele designation of the lowest-numbered allele in the group.

PubMed   |  Alleles that differ only by sequence polymorphisms in introns or in the 5′ and 3′ untranslated regions that flank the exons and introns are distinguished by the use of the seventh and eight digits. For HLA-DPB1 alleles, it was decided to assign new alleles within the existing system; hence, once DPB1*9901 had been assigned the next allele would be assigned DPB1*0102, followed by DPB1*0203, DPB1*0302 etc. With the ever-increasing number of HLA alleles described, it has been decided to introduce colons (:) into the allele names to act as delimiters of the separate fields.

(2019), The Journal of the Korean Society for Transplantation 2. Alleles whose numbers differ in the first four digits must differ in one or more nucleotide substitutions that change the amino-acid sequence of the encoded protein. In addition, formal validation and interpretation rules for the so-called 'multiple allele codes' have been added. Bone Marrow Transplant. In 2002 we faced the issue of the A*02 and B*15 allele families having more than 100 alleles.3 At that time the decision taken was to name further alleles in these families in the rollover allele families A*92 and B*95, respectively. For some purposes it is helpful to provide codes that aid the reporting of certain ambiguous allele ‘strings’. Unfortunately this is not the case, as the number of alleles for certain genes is now fast approaching the maximum possible with the current naming convention. Robinson J, Malik A, Parham P, Bodmer JG, Marsh SGE . For example: The names A*02:100 and B*15:100 will not be assigned. Marsh SGE, Albert ED, Bodmer WF, Bontrop RE, Dupont B, Erlich HA et al. Noninvasive Imaging of Human Immune Responses in a Human Xenograft Model of Graft-Versus-Host Disease. The third and fourth digits are assigned in the order in which the sequences have been determined. Epub 2019 Jul 10.

PubMed Central  (2018), Bone Marrow Transplantation To ensure consistent coding and interpretation of HLA data among the linked computer systems, the World Marrow Donor Association has standardized the extensions of the World Health Organization (WHO) Nomenclature for factors of the HLA system applied in practice. 2018 Apr;45(2):75-87. doi: 10.1111/iji.12356. The DPB1 allele names that have been previously assigned names within the existing system will also be renamed, for example: The ‘w’ will be removed from the HLA-C allele names, but will be retained in the HLA-C antigen names, to avoid confusion with the factors of the complement system and epitopes on the HLA-C molecule, often termed C1 and C2, that act as ligands for the killer-cell Ig-like receptors. 1999 Jul;24(2):119-21. doi: 10.1038/sj.bmt.1701879.

It now covers issues arising when alleles are withdrawn or renamed because of the continuous updating of the WHO HLA nomenclature. The Committee conducted their required annual review of the HLA equivalency tables and identified the following four areas of change: 1. Review and update the current HLA equivalency tables (Tables 4-2 through 4-15) to be more consistent with current nomenclature and account for changes in available testing reagents that may impact testing.

The convention of using a four-digit code to distinguish HLA alleles that differ in the proteins they encode was introduced in the 1987 Nomenclature Report.1, 2 Since then additional digits have been added, and currently an allele name may be composed of four, six or eight digits depending on its sequence.
