摘要: Coeliac disease is strongly associated with HLA-DQ2, but it possible that additional major histocompatibility complex genes also confer susceptibility. Encoded close to HLA-DQ are two genes, TAP1 and TAP2, whose products believed transport antigenic peptides from the cytoplasm into endoplasmic reticulum. Comparison of 81 coeliac patients caucasoid controls revealed an increased frequency alleles TAP1A TAP2A in patient population. However, no significant difference was found when were compared HLA-DR -DQ matched controls, indicating linkage disequilibrium between TAP1A, TAP2A, HLA-DQ2. The TAP gene do not have a influence on susceptibility or resistance Northern European Caucasoid
