Our friends (who are always very supportive of the AFND website, Jill A. Hollenbach @UCSF, Steven J. Mack @UCSF and Martin Maiers @NMDP) have formed the COVID-19 HLA & Immunogenetics Consortium to unite the global community of HLA and immunogenetics experts and leaders in support of these efforts. They invite you to share your expertise as they launch this endeavour by joining the consortium. A project for the next international Histocompatibility Workshop is also planned.


The Allele Frequency Net Database (AFND) provides the scientific community with a freely available repository for the storage of immune gene frequencies in different worldwide populations. Users can contribute the results of their work into one common database and can perform database searches on information already available. We have currently collected data in allele, haplotype and genotype format. However, the success of this website will depend on you to contribute your data.

Does any of this interest you?

How good are the data sets in AFND?

We have classified HLA data sets into "Gold-Silver-Bronce" standards. If you wish to see how many populations are classified as Gold, click here. map
