This report summarizes the new swine leukocyte antigen (SLA) allele sequences and haplotypes designated by the SLA Nomenclature Committee of the International Society for Animal Genetics. There have been 74 new SLA alleles, comprising 18 SLA‐1 alleles, 11 SLA‐2 alleles, six SLA‐3 alleles, two SLA‐6 alleles, one SLA‐DRA allele, 20 SLA‐DRB1 alleles, three SLA‐DQA alleles and 13 SLA‐DQB1 alleles. Twelve new SLA class I and four new class II haplotypes have also been designated. This is the first official update since the 2005 reports on the nomenclature for factors of the SLA class I and II systems. This report also summarizes recent updates to the Immunopolymorphism Database–Major Histocompatibility Complex (IPD‐MHC) website (http://www.ebi.ac.uk/ipd/mhc/sla/). All information has now been integrated to the SLA section of the IPD‐MHC database, which serves as the repository for maintaining a list of all recognized SLA genes and their allelic sequences.
