Biological Context

Subcellular Location: Secreted
Disease Association: Psoriatic arthritis (PSORAS) : An inflammatory, seronegative arthritis associated with psoriasis. It is a heterogeneous disorder ranging from a mild, non-destructive disease to a severe, progressive, erosive arthropathy. Five types of psoriatic arthritis have been defined: asymmetrical oligoarthritis characterized by primary involvement of the small joints of the fingers or toes; asymmetrical arthritis which involves the joints of the extremities; symmetrical polyarthritis characterized by a rheumatoid like pattern that can involve hands, wrists, ankles, and feet; arthritis mutilans, which is a rare but deforming and destructive condition; arthritis of the sacroiliac joints and spine (psoriatic spondylitis). [Disease susceptibility is associated with variants affecting the gene represented in this entry] | Immunodeficiency 127 (IMD127) : An autosomal recessive immunologic disorder characterized by increased susceptibility to pulmonary infection with Mycobacterium tuberculosis. Affected individuals develop recurrent pulmonary tuberculosis, but have no adverse reaction to live BCG vaccination.
