    Summary
    HLA-DRB1 belongs to the HLA class II beta chain paralogs. The class II molecule is a heterodimer consisting of an alpha (DRA) and a beta chain (DRB), 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. It is encoded by 6 exons. Exon one 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 DR molecule the beta chain contains all the polymorphisms specifying the peptide binding specificities. Hundreds of DRB1 alleles have been described and typing for these polymorphisms is routinely done for bone marrow and kidney transplantation. DRB1 is expressed at a level five times higher than its paralogs DRB3, DRB4 and DRB5. DRB1 is present in all individuals. Allelic variants of DRB1 are linked with either none or one of the genes DRB3, DRB4 and DRB5. There are 4 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9. [provided by RefSeq, Jul 2008]

    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.

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
