A new website (http://www.allelefrequencies.net) has been compiled to execute the frequency of alleles at various polymorphic regions of different populations in the field of histocompatibility and immunogenetics. Data for HLA alleles has been added but this will be extended to include frequency data of polymorphisms in other immunogenetic regions, e.g. cytokines, KIR receptors, MIC.
