Nomenclature for factors of the SLA class-I system, 2004.

A systematic nomenclature for the genes and alleles of the swine major histocompatibility complex (MHC) is essential to the development and communication of research in swine immunology. The Swine Leucocyte Antigen (SLA) Nomenclature Committee of the International Society for Animal Genetics has reviewed all of the DNA sequence information for MHC class-I genes, available in GenBank/EMBL/DDBJ databases, and the associated published reports in order to develop such a systematic nomenclature. This report summarizes the proposed nomenclature, which parallels the World Health Organization's nomenclature for factors of the human MHC. The classical class-I SLA genes are designated as SLA-1, SLA-2 and SLA-3; the non-classical as SLA-6, SLA-7 and SLA-8. Nomenclature assignments for all SLA class-I GenBank sequences are now noted. The Committee will add new SLA class-I allele designations, as they are discovered, and will maintain a publicly available list of all recognized genes and alleles by using the International ImMunoGeneTics Project and its Immuno Polymorphism Database/MHC (IPD/MHC) sequence database for MHC sequences in veterinary species.
