The HLA-DQ8 heterodimer (DQA1*03xx/DQB1*0302) was increased in CD patients (29%) compared with controls (10%), but no statistical differences were found.
Celiac disease (CD) patients usually express a DQ2 heterodimer, whose chains DQalpha1*0501/DQbeta1*0201, are encoded by the genes HLA-DQA1*0501 and DQB1*0201, respectively.
