HLA-A is a group of human leukocyte antigens (HLA) that are coded for by the HLA-A locus which is located at human chromosome 6p21.3. HLA is simply the major histocompatibility complex (MHC) specific to humans. HLA-A is one of three major types of human MHC class I cell surface receptors. The others are HLA-B and HLA-C. The receptor is a heterodimer and is composed of a heavy α chain and smaller β chain.
