HLA-DQA2 (Human Leukocyte Antigen DQ Alpha 2): HLA-DQA2 is part of the HLA complex, crucial for immune system regulation through antigen presentation. It encodes an alpha chain that pairs with a beta chain to form the HLA-DQ molecule, which presents foreign antigens to T cells, initiating immune responses. Variations in HLA-DQA2 are associated with susceptibility to autoimmune diseases, underlining its role in immune tolerance and autoimmunity.
