 ### `py-ard` is ARD reduction for HLA in Python
 
-HLA genes regulate cell surface proteins that present cellular antigens to the immune system.
-The exons of HLA that encode peptide binding groove of Antigen Recognition Domain (ARD) are the most polymorphic region of HLA and are important for [HLA matching](https://bethematch.org/patients-and-families/before-transplant/find-a-donor/hla-matching/). The version 3 of HLA [Nomenclature](https://www.theatlantic.com/magazine/archive/2023/04/clint-smith-nomenclature-poem/673097/) was defined by [The WHO Nomenclature Committee](https://hla.alleles.org/nomenclature/committee.html) in 2010 specifying how HLA Alleles are named and grouped. The history of allele typing methods has played a major role in determining resolution and ambiguity of reported HLA. `py-ard` is aware of these various resolutions and grouping and is able to translate from one representation to another based on alleles published quarterly by [IPD/IMGT-HLA](https://github.com/ANHIG/IMGTHLA/).
