According to the results of recent scientific studies there is a strong evidence to characterize celiac disease as genetic disorder associated with antigens of major histocompatibility complex (MCH II) HLA-DQ2 and HLA-DQ8. Different loci of HLA molecules are encoded by specific alleles and their combination determines the individual risk of celiac disease formation. In this article authors discuss data on structure of DQ2 and DQ8 molecules, the frequency of different alleles detection in celiac patients and possible classification of genetic risk of celiac disease formation according to HLA-DQ genotype.
