The downloads on this page are for previous releases of the Allele Name Translation Tool (ANTT). To download the current version (ANTT v0.5.0) click here.

The Allele Name Translation Tool (ANTT) will translate non-colon-delimited HLA allele names (e.g., A*01010101) to their colon-delimited counterparts (e.g., A*01:01:01:01), and will update allele names that have changed as the result of a nomenclature change (i.e., DPB1*0502 will be translated to DPB1*104:01, and HLA-C allele prefixes will be changed from Cw* to C*). In addition the ANTT can be used to translate between any pair of allele naming conventions through the use of customized translation tables.

In addition to translating whole allele names, the ANTT can translate allele-names that have been truncated to two, four, or six digits (e.g., A*01, A*0101, or A*010101) to their colon-delimited counterparts truncated to the appropriate number of polymorphic domains (e.g., A*01, A*01:01, or A*01:01:01), and can translate each of the alleles in an ambiguous allele string (i.e., A*01010101/A*01010102N/A*010102 will be translated to A*01:01:01:01/A*01:01:01:02N/A*01:01:02).

Finally, the ANTT can translate allele names that include locus prefixes (e.g., A*01010101) as well as allele names that do not include locus prefixes (e.g., 01010101). For details about installing and using the ANTT, read The ANTT User Guide.

The ANTT uses translation tables derived from the translation source table available at; this file can also be obtained via FTP from ANTT translation tables can be generated from a translation source file using the ANTT File Manager (distributed with the ANTT).

ANTT users are encouraged to join the ANTT User Mailing List for news and notifications about the tool.

System Requirements
The ANTT runs in the Microsoft .NET framework (version 3.5 SP1) in Windows XP and Vista, should run natively in Windows 7, and can be run on Apple OSX, BSD, and Linux platforms using the Mono open source .NET development framework (version 2.4).
