We aimed to investigate the association of the ERAP1, IL23R and TNFSF15 regions and the susceptibility to and protection from AS in HLA-B27-positive individuals. METHODS: A total of 200 unrelated AS patients and 559 healthy unrelated subjects, all HLA-B27 positive, were tested. Twenty single nucleotide polymorphisms (SNPs) were...
