We report variants associated with the risk of sarcoidosis such as HLA-C*03:04, HLA-DRB1*12:01, HLA-DRB1*14:54, and a protective variant HLA-DPB1*04:01, previously described in other populations6,7,11,12, associated with sarcoidosis also in Koreans. The gene discussed is HLA-C; the disease is sarcoidosis.
