HLA-C (P10321) variants and mutations

HLA-C (also known as P10321) is a human protein-coding gene encoding a HLA class I histocompatibility antigen, C alpha chain protein. It presents intracellular peptides to cytotoxic T cells and is also a major ligand for inhibitory and activating killer-cell immunoglobulin-like receptors on natural-killer cells. Allelic variation influences antiviral immunity, reproductive immunology, autoimmune risk, and outcomes of hematopoietic transplantation. This analysis covers 1,161 HLA-C variants and mutations. Of these, 96% have computational variant effect predictions. Disease context includes COVID-19, psoriasis, and diffuse large B-cell lymphoma. Example HLA-C variants include R2L, R2P, and R2Q.
