The Allele Frequency Net Database

"We want to thank all individuals who contributed to the Rare Alleles Project presented at the 15th IHWS in Brazil (September, 2008). This has now been published:

Middleton D, Gonzalez F, Fernandez-Vina M, Tiercy J-M, Marsh SGE, et al. (2009) A bioinformatics approach to ascertaining the rarity of HLA alleles. Tissue Antigens 74:480-485.

Our intention is to continue this project for the next International Workshop in Liverpool on 2012 and to work with Marcelo Fernandez-Vina and ASHI in taking this forward. Please contact us if you wish to participate."

Introduction

Allele Frequencies in Worldwide Populations

The Allele Frequency Net Database (AFND) provides a central source, freely available to all, for the storage of allele frequencies from different polymorphic areas in the Human Genome. 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. The success of this website will depend on you to contribute your data.

Database information

Polymorphic Region	Population Studies	Gene/Allele Data	Haplotype Data	Genotype Data
HLA	856	841	348	-
KIR	196	196	-	87
Cytokine	113	113	-	-
MIC	58	58	20	-
Totals	1,223	1,208	368	87

The current number of frequencies stored in our database is: 88,127 (HLA), 4,959 (KIR), 3,603 (Cytokine) and 723 (MIC) from 4,333,813 individuals.

We have updated the website with the new IMGT/HLA nomenclature guidelines.
