What is the Allele Frequency Net Database?

The Allele Frequency Net Database (AFND) is a public database which contains frequency information of several immune genes such as Human Leukocyte Antigens (HLA), Killer-cell Immunoglobulin-like Receptors (KIR), Major histocompatibility complex class I chain-related (MIC) genes, and a number of cytokine gene polymorphisms.

What type of frequency data can I access?

The AFND contains information of allele, haplotype and genotype frequencies depending of the polymorphism. Users can navigate in a number of different options to search frequencies and other on-line tools.

How can I search frequency information?

Please select one of the options from the left menu on the main page. In each searching tool you will find a set of instructions to perform a particular query. A full list of all available searches can be found on the Site Map.

How can I contribute to this website?

If you have a population study that has not been entered on the Allele Frequency Net Database you can submit your information by entering demographic data in the submission section. After entering your demographic data you will receive a spreadsheet to enter the corresponding frequencies.
