HLA-B58

HLA-B58 is an HLA-B serotype. B58 is a split antigen from the B17 broad antigen, the sister serotype B57. The serotype identifies the more common HLA-B*58 gene products. B*5801 is associated with allopurinol induced inflammatory necrotic skin disease.

Disease

HLA-B*5801 is involved in allopurinol sensitive drug induced Stevens–Johnson syndrome. Allopurinol is a frequent cause of severe cutaneous adverse reactions, including drug-hypersensitivity syndrome, Stevens–Johnson syndrome, and toxic epidermal necrolysis. The association with allopurinol sensitivity in SJS/TEN was extremely strong in Asia, and somewhat less associated in Europeans.
