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]
