For example, B*08, B*27, and B*38 can induce PsA development, whereas HLA-B*27:05:02 is associated with arthritis, enthesites, dactylites, and symmetric sacroiliitis, and HLA-B*08:01:01 and HLA-C*07:01:01 are associated with erosive arthritis, dactylites, and asymmetric sacroiliitis [106,107]. Here, HLA-B is linked to Sacroiliac arthritis.
