[[http://www.uniprot.org/uniprot/1B15_HUMAN 1B15_HUMAN]] Defects in HLA-B are a cause of susceptibility to Stevens-Johnson syndrome (SJS) [MIM:[http://omim.org/entry/608579 608579]]. A rare blistering mucocutaneous disease that share clinical and histopathologic features with toxic epidermal necrolysis. Both disorders are characterized by high fever, malaise, and a rapidly developing blistering exanthema of macules and target-like lesions accompanied by mucosal involvement. Stevens-Johnson syndrome is a milder disease characterized by destruction and detachment of the skin epithelium and mucous membranes involving less than 10% of the body surface area. Ocular symptoms include ulcerative conjunctivitis, keratitis, iritis, uveitis and sometimes blindness. It can be caused by a severe adverse reaction to particular types of medication, although Mycoplasma infections may induce some cases. Note=Allele B*15:02 is associated with susceptibility to Stevens-Johnson syndrome.
