HLA-B51

HLA-B51 (B51) is an HLA-B serotype. The serotype identifies the more common HLA-B*51 gene products.[1]

B51 is a split antigen of the broad antigen B5, and is a sister serotype of B52.[2] There are many alleles within the B*51 allele group. B51 is associated with several diseases, including Behçet's disease.

Alleles

There are 71 alleles, 57 amino acid sequence variants in B51 of which 4 are nulls. Of these only 9 are frequent enough to have been reliably serotyped. B*5101 is the most common, but others have a large regional abundance.

Disease associations

By serotype

Bw51 was associated with Behçet's disease,[5] in endemic (versus epidemic) mucocutaneous lymph node syndrome,[6] susceptibility to the virus that causes German measles infection.[7]

In Behçet's disease

Behçet's disease is an inflammation of the wall of blood vessels that can involve the eyes, skin, and the rest of the body.[8] Several alleles of B51 (B*5101, B*5108, B*5105, and B*5104) are found in disease, and linkage to markers, D6S285, in the HLA locus was strong (P<0.005).[9] Homozygotes of B51 showed considerably high risk for disease indicating a possible gene-dose effect. B51 is capable of distinguishing several varieties of disease. HLA-B51 is found more frequently in disease that has an eye involvement.[10] However it is less common in some regions when there is increased neurological involvement.[11] The MICA*009 allele has been found to also associated with ABD when B51 is also present,[12] IL-8 and other cytokines may also be involved.[13][14] Sister chromatid exchange has also been observed more frequently in B51(+) ABD.[15]

However, B51 tends not to be found in ABD when a certain SUMO4 gene variant is involved,[16] and symptoms appear to be milder when HLA-B27 is present.[17]
