Polymorphisms in the endoplasmic reticulum aminopeptidase genes ERAP1 and/or ERAP2 are strongly associated with the diseases AS, psoriasis, IBD and Behcet’s disease. Robust genetic interaction exists between ERAP1 and the HLA Class I alleles HLA-B27 and –B40 (associated with AS), -Cw6 (in psoriasis), and -B*51 (in Behcet’s disease). In AS, two ERAP1 haplotypes are disease associated, tagged either by rs30187 (thought to be directly disease-associated) or rs10050860 (which lies on a disease-associated haplotype). Protective alleles of rs30187 are associated with reduced peptidase activity. We hypothesized that other AS-associated ERAP1 and ERAP2 genetic variants would also either lead to reduced function or expression of the respective gene.
