HLA-B52 (B52) is an HLA-B serotype. The serotype identifies the more common HLA-B*52 gene products.^[1]

B52 is a split antigen of the broad antigen B5, and is a sister type of B51. B*5201 likely formed as a result of a gene conversion event between another HLA-B allele and HLA-B*5101.^[2] There are a number of alleles within the B*52 allele group.^[3]

Alleles

There are 18 alleles, with 14 amino acid sequence variants in B52. Of these only 9 are frequent enough to have been reliably serotyped. B*5201 is the most common, but others have a large regional abundance.

Disease

In ulcerative colitis

HLA-B52 appears to have the strongest linkage to ulcerative colitis in Japan.^[6][7] This form of disease is frequently found with Takayasu's arteritis.^[8][9]

In Takayasu's arteritis

Takayasu's arteritis appears to have an independent link to B52 associated disease.^[10][11] The association with B*5201 increases risk of pulmonary infarction, ischemic heart disease, aortic regurgitation, systemic hypertension, renal artery stenosis, cerebrovascular disease, and visual disturbance.^[12]
