HLA-DR3 and DR7 have in common a frequent association with the allele DQ2. It now seems that the "primary" association with celiac disease may be that of HLA-DQ2.^2-5 It would be interesting to see if the nonresponders with HLA-DR3 and DR7 in the study by Weissman et al also have HLA-DQ2.

In the case of celiac disease, a collaborative study by the Ninth Histocompatibility Workshop found that in a group of patients with celiac disease who lacked either DR3 or DR7, some had DQ2 in the absence of DR3 or DR7, while . . . [Full Text PDF of this Article]
