Frequently Asked Questions (FAQs)

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 at allele, haplotype and genotype level depending on the polymorphism. Users can navigate in a number of different options to search population frequencies. There are also some other tools that can be useful for the community.

How can I search frequency information?

Please select one of the options from the left menu on the home page. For each searching tool you will find a set of instructions to perform a particular query.

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 data by entering the information using the AFND Upload Tool.
