A higher frequency of HLA-B38 was noted
psoriatic arthritis patients with
erythroderma. Psoriatic arthritis is linked to MICA and/or
B39 in other peoples. In
Pemphigus vulgaris a haplotype containing B38 was identified and found to be shared between Spanish and Jewish patients. Linkage studies indicate a factor in the HLA-class I region is more greatly associated, with HLA-B38 so far the only linked allele ==References==
