. Conclusion: When PTDM is performed, a positive HLA DQA1*05 genotype does not associate a higher risk of treatment cessation.doi:10.1093/ecco-jcc/jjab232.489Fuentes-Valenzuela EGarcía-Alonso F JMaroto-Martín CJuan-Casamayor LGarrote Adrados J A...
Patients negative for these HLA molecules mostly possess HLA-DQA1*0201-DQB1*0202 haplotypes (HLA-DQ2.2) [102]. HLA-DQ2.2 carriers have an inconsequential risk of developing CD. In contrast, approximately 20–30% of the healthy Caucasian population is HLA-DQ2 positive. A gender-specific ...
frequently together with CeD. The haplotypes HLA- DRB1*03:01-DQA1*05:01-DQB1*02:01 and HLA-DRB1*04:01-DQA1*03:01-DQB1*03:02 were significantly overrepresented in APS compared with AITD (HT and GD) or controls, whereas the HLADRB1*15:01-DQA1*01:02-DQB1*06:02 haplotype is protect...

The development of gliadin-specific antibody and T-cell responses were longitudinally monitored in young children with genetic risk for celiac disease (CD).291 newborn children positive for HLA-DQB1*02 and -DQA1*05 alleles were followed until 3-4 years of age by screening for tissue ...
DQA1 No DQB1 Uncertain∗ DPA1 No DPB1 Uncertain ∗ Unknown indicates that the effect of matching has not been evaluated; uncertain indicates that studies disagree as to the importance of these loci in matching. Does the race or ethnicity of the donor need to be the same as the ...
leprae . With the purpose of identifying genes of susceptibility, the present study investigated the possible role of HLA-DRB1 and DQA1/DQB1 alleles in susceptibility to leprosy, and whether they account for the heterogeneity in immune responses observed following infection in a Southern Brazilian ...

haplotype, which is also common to many other autoimmune disorders[20]. The small proportion of patients with coeliac disease who do not express HLA-DQ2 molecules are HLA-DQ8-positive, where the α and β chains of the HLA-DQ8 molecule are encoded by HLA-DQA1*03 and HLA-DQB1*0302, ...
The dominant, significant positive association was seen with DQA1*02:01, DQB1*02:02, and DRB1*07:01. These alleles were increased across all phenotypic subtypes in patients with prosthetic failure. The alleles were in strong linkage disequilibrium and occurred on one associated haplotype. A ...
