HLA-B*27 is a specific human leukocyte antigen (HLA) gene variant that is associated with certain autoimmune diseases of inflammatory-rheumatoid appearance, particularly ankylosing spondylitis (AS, Morbus Bechterew) and various athritides like rheumatoide arthritis (RA) or juvenila idiopathic arthritis (JIA).
Besides the rheumatoid factor (RF), HLA-B*27is probably the best-known blood value in the context of rheumatism diagnostics.
The presence of HLA-B*27 is not a definitive diagnosis, but it is a predisposing genetic marker for the diagnosis of the above-mentioned diseases.
