HLA-B and nasopharyngeal carcinoma: The imputation method for fine‐mapping has been successfully applied to other immune‐related disease such as celiac disease, Graves’ disease and type 1 diabetes.20, 26, 27 Although we did not genotype the HLA region directly, we fine‐mapped this region and repeated associations of some important classic alleles associated with NPC, such as protective alleles HLA‐A*11:01, HLA‐B*13:01 and risk alleles HLA‐A*2, HLA‐B*46:01.
