    Summary
    HLA-DQB1 belongs to the HLA class II beta chain paralogs. This class II molecule is a heterodimer consisting of an alpha (DQA) and a beta chain (DQB), both anchored in the membrane. It plays a central role in the immune system by presenting peptides derived from extracellular proteins. Class II molecules are expressed in antigen presenting cells (APC: B lymphocytes, dendritic cells, macrophages). The beta chain is approximately 26-28 kDa and it contains six exons. Exon 1 encodes the leader peptide, exons 2 and 3 encode the two extracellular domains, exon 4 encodes the transmembrane domain and exon 5 encodes the cytoplasmic tail. Within the DQ molecule both the alpha chain and the beta chain contain the polymorphisms specifying the peptide binding specificities, resulting in up to four different molecules. Typing for these polymorphisms is routinely done for bone marrow transplantation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2011]

    Celiac disease

    Summary from GeneReviews: Celiac Disease Go to GeneReviews

    Disease Characteristics
    Celiac disease is a systemic immune disease that can be associated with gastrointestinal findings (diarrhea, weight loss, abdominal pain, anorexia, lactose intolerance, abdominal distention, and irritability) and/or highly variable non-gastrointestinal findings (iron-deficiency anemia, dermatitis herpetiformis, chronic fatigue, joint pain/inflammation, migraines, depression, attention-deficit disorder, epilepsy, osteoporosis/osteopenia, infertility and/or recurrent fetal loss, vitamin deficiencies, short stature, failure to thrive, delayed puberty, dental enamel defects, and autoimmune disorders). Classic celiac disease, characterized by mild to severe gastrointestinal symptoms, is less common than nonclassic celiac disease, characterized by absence of gastrointestinal symptoms.
    Diagnosis Testing
    The diagnosis of celiac disease relies on characteristic histologic findings on small-bowel biopsy and clinical and/or histologic improvement on a gluten-free diet. Most individuals with celiac disease have celiac disease-associated antibodies and specific pairs of allelic variants in two HLA genes, HLA-DQA1 and HLA-DQB1. Because 30% of the general population has one of the celiac disease-associated HLA alleles and only 3% of individuals with one or both of these alleles develop celiac disease, presence of celiac disease-associated HLA alleles is not diagnostic of celiac disease; however, their absence essentially excludes a diagnosis of celiac disease.
    Genetic Counseling
    Celiac disease is a multifactorial disorder resulting from the interaction of HLA-DQA1 and HLA-DQB1 gene variants known to be associated with celiac disease susceptibility, less well-recognized variants in non-HLA genes, gliadin (a subcomponent of gluten), and other environmental factors. Some empiric risk data are available for at-risk relatives.

    Jakob-Creutzfeldt disease

    Summary from GeneReviews: Genetic Prion Diseases Go to GeneReviews

    Disease Characteristics
    Genetic prion diseases generally manifest with cognitive difficulties, ataxia, and myoclonus (abrupt jerking movements of muscle groups and/or entire limbs). The order of appearance and/or predominance of these features and other associated neurologic and psychiatric findings vary. Familial Creutzfeldt-Jakob disease (fCJD), Gerstmann-Straussler-Scheinker (GSS) syndrome, and fatal familial insomnia (FFI) represent the core phenotypes of genetic prion disease. Note: A fourth clinical phenotype, known as Huntington disease like-1 (HDL-1) has been proposed, but this is based on a single report, and the underlying pathologic features would categorize it as a GSS. Although it is clear that these three subtypes display overlapping clinical and pathologic features, recognition of these phenotypes can be useful when providing affected individuals and their families with information about the expected clinical course. The age at onset ranges from the third to ninth decade of life. The course ranges from a few months to several years (typically five to seven years; in rare instances, >10 years). Death generally results from infection, either by pneumonia (typically from aspiration) or urosepsis.
    Diagnosis Testing
    PRNP is the only gene in which mutation is known to cause genetic prion disease. The presence of a PRNP mutation is necessary to establish the diagnosis of genetic prion disease in a symptomatic individual. Sequence analysis of the PRNP is available on a clinical basis; it is possible that this test method does not detect all disease-causing mutations; thus, the absence of a PRNP disease-causing mutation does not rule out the diagnosis of genetic human prion disease.
    Genetic Counseling
    Genetic prion disease is inherited in an autosomal dominant manner. Most individuals diagnosed with genetic prion disease have an affected parent. However, a proband with genetic prion disease may have the disorder as the result of a de novo gene mutation. The proportion of cases caused by de novo gene mutations is unknown. Each child of an individual with a disease-causing PRNP mutation has a 50% chance of inheriting the mutation. Prenatal testing for pregnancies at increased risk of having a PRNP mutation is available on a very limited basis.

    Multiple sclerosis susceptibility

    Summary from GeneReviews: Multiple Sclerosis Overview Go to GeneReviews

    Disease Characteristics
    Multiple sclerosis (MS) is an inflammatory, demyelinating, neurodegenerative disorder of the central nervous system (CNS) of unknown etiology. The peak onset is between age 20 and 40 years; it may develop in children and has also been identified in persons over age 60 years. Women are affected approximately twice as often as men. The most common clinical signs and symptoms, occurring in isolation or in combination, include sensory disturbance of the limbs (~30%), partial or complete visual loss (~15%), acute and subacute motor dysfunction of the limbs (~13%), diplopia (7%), and gait dysfunction (5%). The course may be relapsing-remitting or progressive, severe or mild, and may involve the entire neuroaxis in a widespread fashion or predominantly affect the spinal cord and optic nerves. The four clinical phenotypes of MS are: relapsing-remitting MS (RR-MS) (initially occurring in more than 80% of individuals with MS); primary progressive MS (PP-MS) (occurring in 10%-20% of individuals with MS); progressive relapsing MS (PR-MS) (a rare form); and secondary progressive MS (SP-MS), to which approximately half of all persons diagnosed with RR-MS convert within a decade after the initial diagnosis.
    Diagnosis Testing
    Multiple sclerosis is primarily a clinical diagnosis. The RR-MS phenotype is diagnosed in individuals who have (1) at least two clinical attacks (each lasting >/=24 hours and separated by >/=1 month) or a slow, progressive course for at least six months, and (2) lesions in more than one area or functional system of the brain or spinal cord. Diagnostic criteria for PP-MS include a minimum period of clinical progression of at least 12 months and onset between age 25 and 65 years; three proposed categories include definite PP-MS, probable PP-MS, and possible PP-MS. More recent diagnostic criteria specifically integrate MRI with clinical and paraclinical methods.
    Genetic Counseling
    Available data suggest that multiple sclerosis is inherited as a complex multifactorial disorder that results from the interaction of genetic and environmental factors. Estimated risk to the sibs of a proband is 3.0%-5.0%, increasing to 29.5% if one or both parents have MS. Risk to the offspring of a person with MS is 2.0%-3.0% and higher if both parents have MS.

    2. NM_001243962.1NP_001230891.1  HLA class II histocompatibility antigen, DQ beta 1 chain isoform 1 precursor

      Status: REVIEWED

      Description
      Transcript Variant: This variant (3) has the same exon combination as variant 1 but represents the DQB1*02:01:01:01 allele of the HLA-DQB1 gene, as represented in the alternate locus group ALT_REF_LOCI_2 of the reference genome. It encodes isoform 1.
