Knowing the distribution of HLA genotypes has proven to be useful for the prediction of celiac disease in the general population1 Celiac disease is an immune disorder strongly associated with the HLA‐DQA1*05:01‐DQB1*02:01 (DQ2.5) haplotype and to a lesser extent DQA1*03:01‐DQB1*03:02 (DQ8) haplotype. The gene discussed is HLA-DQA1; the disease is immune system disorder.
