What does HLA-DRB1 do?

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.

Does everyone have HLA-DRB1?

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 5 related pseudogenes: DRB2, DRB6, DRB7, DRB8 and DRB9. Prevalence of the HLA-DRB1*10:01 allele was greatly increased in people with anti-IgLON5 disease.

What are HLA antigens?

Human leukocyte antigens (HLA) are genes in major histocompatibility complexes (MHC) that help code for proteins that differentiate between self and non-self. They play a significant role in disease and immune defense. They are beneficial to the immune system but can also have detrimental effects.

Which HLA type is associated with rheumatoid arthritis?

Inherited susceptibility to rheumatoid arthritis (RA) is associated with the DRB1 genes encoding the human leukocyte antigen (HLA)-DR4 and HLA-DR1 molecules.

What is an HLA test?

HLA testing identifies the major HLA antigens that are present on the surface of an individual’s cells and the antibodies to HLA antigens as well as the genes that are responsible for HLA antigens, primarily to match transplant donors and recipients.

What does HLA DR4 stand for?

From Wikipedia, the free encyclopedia. human major histocompatibility complex, class II, DR4.

How many versions of HLA-DRB1 are there?

Each MHC class II gene has many possible variations, allowing the immune system to react to a wide range of foreign invaders. Researchers have identified hundreds of different versions (alleles) of the HLA-DRB1 gene, each of which is given a particular number (such as HLA-DRB1 *04:01).

How is HLA-DRB1 related to autoimmune diabetes?

Meta-analysis shows that HLA-DRB1 SNPs are associated with susceptibility to latent autoimmune diabetes in adults. Contribution of HLA alleles and HLA-associated single-nucleotide polymorphisms to the development and titer of antibodies against interferon beta in multiple sclerosis.

Which is a risk haplotype for HLA-DRB1 * 16 : 02?

Results show that the DRB1*16:02 allele is associated with anti-N-methyl-D-aspartate receptor encephalitis. HLA-DRB1*04:10 is a risk allele and HLA-DRB1*04:10-HLA-DQB1*04:02 a risk haplotype for Moyamoya disease (MMD). In addition, HLA-DRB1*04:10 is associated with thyroid disease in MMD patients.

Is there an association between HLA-DRB1 and FVIII inhibitor?

An association between HLA-DRB1*01:01 and paucity of FVIII inhibitor showed that this allele has probably a protective effect in severe hemophilia A patients in Iran. The expression of multiple sclerosis-associated alleles in heterozygous MS patients was always higher than the nonassociated alleles.
