Nomenclature for factors of the HLA system, 1989

The WHO Nomenclature Committee for factors of the HLA system met during the 7th International Congress of Immunology in Berlin in August 1989 to consider additions to the previous report on nomenclature for factors of the HLA system 1987 (WHO Nomenclature Committee, 1988; Bodmer et al. 1989). This report, taking into account only new data on DNA sequences of alleles and of three new loci, therefore concerns only the naming of new alleles and loci defined by nucleotide or inferred amino acid sequences. It should therefore be considered as a supplement to and used in conjunction with the 1987 report cited above. Thus, Table 1 -Names for genes in the HLA regionincludes the new genes named for the first time in this report and updates Table 1 of the 1987 report. Table 2-Designations of H L A A , B, and C alleles-updates Table 3 of the 1987 report, and Tables 3, 4, and 5-Designations of the H L A D R , D Q , and D P allelesupdate Table 4 of the 1987 report. Tables 5-9 and comments of the 1987 report relating to serological and
