HLA-B51, a split product of HLA-B5, has been found to be associated with the disease in Japanese patients,11 with a calculated relative risk of 9.4. The frequency of this antigen in control subjects was 12%, whereas in patients it was 57% (58% in patients with the complete form of the disease versus. 54% in those with the incomplete form).
2017-04-25 1997-08-01 2016-08-19 HLA-B51 Behçet’s disease 508 Acta Medica Iranica, Vol. 46, No. 6 (2008) MIB-348, C1-4-1-217) and HLA-B51 were found to be strongly associated with BD. Of these alleles HLA-B51 is the most strongly associated allele. The HLA-DRB1 gene provides instructions for making a protein that plays a critical role in the immune system. The HLA-DRB1 gene is part of a family of genes called the human leukocyte antigen (HLA) complex. The HLA complex helps the immune system distinguish the body's own proteins from proteins made by foreign invaders such as viruses and bacteria.
Patienter som behandlas med abakavir och är positiva för HLA-B*5701 har en markant förhöjd risk att utveckla en överkänslighetsreaktion av läkemedlet inom Planerar du att besöka Sahlgrenska Universitetssjukhuset? Om du har en avtalad tid och har symtom på luftvägsinfektion eller feber kontakta snarast HLA-typning. Bakgrund. HLA betyder Human Leukocyte Antigen som på svenska kan översättas till vävnadstyp. HLA- molekylen Beçhets syndrom: HLA-B51. Även denna patient testade positivt för HLA-B51, vilket ändrade arbetsdiagnosen från PAN till neuro-Behçet.
2018-03-07 · Several HLA-B51 subtypes have been described, of which especially B*51:01, B*51:02(01), B*51:08, B*51:09, and B*51:22 seem to be associated with BD risk [91, 92]. Contribution to Disease. The role of HLA-B51 in the pathogenesis of BD is not fully understood.

In ca. 70% der Fälle kann bei Patienten mit Morbus Behçet das HLA-Antigen HLA-B51 nachgewiesen werden. Zur Diagnosestellung gehört ein ophthalmologisches Konsil. 5.1 Klassifikationskriterien. Hauptkriterium für das Vorliegen eines Morbus Behçet sind

One-third to two-thirds of people with Behçet disease have the HLA-B51 variation, but most people with this version of the HLA-B gene never develop the disorder. To quantify by meta-analysis the genetic effect of the HLA-B5 or HLA-B51 (HLA-B51/B5) allele on the risk of developing Behçet's disease (BD) and to look for potential effect modifiers. Thus, the results of this study confirms that HLA B51 is associated with Behcet’s disease, but these data also suggest that HLA-B51 may also play a hereto unrecognized role in either inducing, modulating, or upregulating other forms of autoimmune disease to cause a 20 fold increase in HLA-51 prevalence from reference populations. Several versions of the HLA-B gene, particularly HLA-B51, are associated with an increased risk of developing Behçet disease, a chronic inflammatory condition that affects many parts of the body. This association is strongest in people from Japan, the Middle East, and other parts of Asia. HLA-B51 is the primary gene involved in the pathogenesis of Behçet disease that can aid the diagnosis.

However, its contribution to the overall genetic BD susceptibility was estimated about to be 20% [ 13 ].

The HLA-B51 allele is known to be associated with Behcet's disease (BD) in many ethnic group. However, it has not yet been clarified whether the HLA-B51 gene itself is the pathogenic gene related to BD or whether it is some other gene in linkage disequlibrium with HLA-B51. (3)hla-b51の陽性（約60％）、a26（約30％）。 (4)病理所見 急性期の結節性紅斑様皮疹では、中隔性脂肪組織炎で、浸潤細胞は多核白血球と単核球である。初期に多核球が多いが、単核球の浸潤が中心で、いわゆるリンパ球性血管炎の像をとる。

The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score cannot be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein. HLA-B51 Determination.
Although many people with Behçet disease have the HLA-B51 variation, most people with this version of the HLA-B gene never develop the condition. It appears likely that other factors, such as viral or bacterial infections and changes in other genes, also influence the development of this complex disorder.
The serotype identifies the more common HLA-B*51 gene products.
However, owing to a low prevalence of B51 positivity in BD patients in Ireland, a multifactorial pathogenesis is suggested. Test name: HLA-B51(5) Special precautions & notes: DNA test by PCR-SSO for Behcets syndrome (not diagnostic) Container: EDTA (Lavender top) Ideal volume (mL): 3 mL Referred outside NBT for analysis? No Discipline: Immunology Turnaround time: 14 days HLA-B51 is only associated with 5% of Behcet's cases. As a result, researchers and doctors think other factors—including infections and environmental exposures—also play a part.
