253 Possible Causes for HLA-B8

  • Adrenal Insufficiency

    Genetic risk None HLA -B8, -DR3, and -DR4 genes confer risk 2.[aafp.org]

  • Primary Sclerosing Cholangitis

    Thus, "A HLA association in PSC was first identified for HLA-B8 (i.e. HLA-B*0801) and DR3 (i.e. DRB1*0301)[24,50].[psc-literature.org] HLA-B8, HLA-DR3, and HLA-Drw52a alleles have an increased prevalence in patients with PSC, suggesting a genetic predisposition.[symptoma.com] […] the portal circulation and from exposure to toxic bile acids has been postulated. [14] A genetic predisposition has been suggested because of an increased prevalence of HLA-B8[emedicine.medscape.com]

  • Graves Disease

    0.3% of men 85% of patients are women (female to male ratio is 4:1), usually ages 20 - 40 years; men are usually older 60% concordance in identical twins; associated with HLA-B8[pathologyoutlines.com] An autoimmune disease with stimulating anti-TSH receptor antibodies a type II hypersensitivity anti-microsomal, anti-thyroglobulin antibodies also present Female dominant HLA-B8[step2.medbullets.com] […] and HLA-DR3 Sites Global involvement of thyroid gland Pathophysiology Exact cause is unclear It is believed to involve a combination of genetic and environmental factors[pathologyoutlines.com]

  • Systemic Lupus Erythematosus

    Factors leading to SLE include: Genetic predisposition, incuding haplotype HLA-B8, -DR 3 Exposure to sunlight Viral infection , particularly Epstein-Barr virus Hormones Toxins[dermnetnz.org] ) reveal that HLA-A1, HLA-B8, and HLA-DR3 are more common in persons with SLE than in the general population.[emedicine.medscape.com] […] however, it was determined that these loci had a lower significance level and a lower contribution to individual risk for SLE. [ 31 ] Studies of human leukocyte antigens (HLAs[emedicine.medscape.com]

  • Herpes Gestationis

    An additional laboratory finding in patients with HG is their increased frequency of the HLA-B8 and HLA-DR3 haplotypes as well as the HLA-DR3, -DR4 paired haplotype.[ncbi.nlm.nih.gov] In herpes gestationis, immunofluorescence studies were consistently positive, there was a high frequency of HLA-B8 and an association with autoimmune thyrotoxicosis.[thedoctorsdoctor.com] HLA-A1, B8, DR3 is known to be in linkage disequilibrium with a deletion of C4A (the C4 null allele or C4QO).[dermaamin.com]

  • Chronic Active Hepatitis B

    The apparent predisposition of individuals with HLA-B8 and DR3 haplotypes to develop IACAH suggests that genetically conditioned abnormalities may have a role in pathogenesis[hepatitiscentral.com]

  • Sjogren's Syndrome

    These "histocompatibility antigens" may include HLA-B8 and HLA-DR3.[resources.lupus.org] […] and HLA-B8 are generally found in Caucasian patients, while HLA-DR5 is related to Greek and Israeli patients. [60] Multiple genome-wide association scans may be conducted[en.wikipedia.org] In white persons, for instance, the condition is linked to human leukocyte antigen (HLA)–DR3, HLA-DQ2, and HLA-B8, [10] whereas the linkage is to HLA-DRB1*15 in Spanish persons[emedicine.medscape.com]

  • Myasthenia Gravis

    The early peak shows a female predominance, approximately 3:1, and an association with HLA-B8, HLA-DR3, and HLA-DR1, the latter being more specific for ocular MG.[eyewiki.aao.org] This suggests an association of MG with HLA B8 and DR3. In terms of underlying genetic abnormalities, work is ongoing [ 8 ] .[patient.info] In people 40 there is a higher incidence of HLA A1, B8, and DRW3 in patients with MG, and in those 40 there is a correlation with HLA A3, B7, and DRW2.[medicine.yale.edu]

  • Autoimmune Hepatitis
