HLA-DRB1 and sarcoidosis: For instance, in an earlier study [1], we reported an interaction between HLA-DRB1 and ANXA11. ANXA11 is a crucial locus as it has been reported in various populations as a susceptible locus for sarcoidosis [20–23], and it is also linked to various sarcoidosis subphenotypes, particularly disease chronicity [24].
