HLA-DRB1 and diffuse large B-cell lymphoma: Two different three-stage GWAS studies in European populations, found that variant rs10484561 is associated with FL risk (OR1 = 1.95; OR2 = 1.64; 95% CI1 = 1.72–2.22; 95% CI2 = 1.45–1.86; p < 1 × 10−8) which, in addition, was later found to be implicated in DLBCL risk and in complete linkage disequilibrium with the HLADRB1*01:01 ̃DQA1*01:01 ̃DQB1*05:01 haplotype (LD-r2 = 1.0).
