Of the HLA alleles, only HLA-DRB1*0803 showed genome-wide significance as a risk factor for sarcoidosis (PGC = 4.1 × 10−8, OR = 1.82, 95% CI = 1.46–2.26); HLA-DQB1*0601 showed the next highest significance as a risk allele for sarcoidosis (PGC = 1.5 × 10−7, OR = 1.32, 95% CI = 1.12–1.56). Here, HLA-DRB1 is linked to sarcoidosis.
