- To determine the frequency of class I and class II HLA antigens and the allelic variants of the class II HLA antigens, DR and DQ, in patients with PV and to determine the relative risk. (nih.gov)
- These split antigens are the allele products of the DQB1*0302 and DQB1*0305, respectively. (wikipedia.org)
- DQ8 is determined by the antibody recognition of β8 and is complicated by the fact that DQ8 recognizes some HLA-DQB1*03 encoded isoforms well, partially or not well at all (See serology) DQ β3.2 and β3.5 are best recognized as DQ8. (wikipedia.org)
- Using long-read sequencing, we identified 16 Mamu-E isoforms and all Mamu-E splicing junctions were detected among HLA-E isoforms in humans. (bvsalud.org)
- DQ8 increases the risk for rheumatoid arthritis and is linked to the primary risk locus for RA, HLA-DR4. (wikipedia.org)
- Infrequently, DQA1*0302:DQB1*0302, but this substitution of the alpha chain, DQA1**0301 versus *0302, is outside the binding cleft and appears not to alter DQ8 function. (wikipedia.org)
- Eight of 35 CBZ-SJS/TEN patients carried HLA-B*15:02 (22.9%) versus 2 of 125 in CBZ-tolerant control patients (OR = 18.222, 95% CI = 3.662-90.662, p = 0.000). (nih.gov)
- The association of PV with the HLA serotypes suggests that there is a genetic predisposition to the disease. (nih.gov)
- A role of genetic factors such as HLA alleles in the development of VKH was first considered in 1976, and was supported by the simultaneous development of VKH in monozygotic twins [3]. (researchsquare.com)
- CBZ-SJS/TEN patients and CBZ-tolerant control patients were genotyped for HLA-B*15:02 by PCR amplification using sequence-specific primers. (nih.gov)
