HLA-B27 is implicated in other types of seronegative spondyloarthropathy, such as reactive arthritis, acute anterior uveitis, iritis, Crohn's and ulcerative colitis associated spondyloarthritis. The shared association with HLA-B27 leads to increased clustering of these diseases. [10] [11] HLA antigens have been studied in relation to autism. [12]
HLA region of Chromosome 6. The human leukocyte antigen (HLA) system is a complex of genes on chromosome 6 in humans that encode cell-surface proteins responsible for regulation of the immune system. [1] The HLA system is also known as the human version of the major histocompatibility complex (MHC) found in many animals. [2]

The association of AS with HLA-B27 suggests the condition involves CD8 T cells, which interact with HLA-B. [22] This interaction is not proven to involve a self-antigen, and at least in the related reactive arthritis, which follows infections, the antigens involved are likely to be derived from intracellular microorganisms.

Namely, in 1962 van Rood analyzed reaction patterns of 60 sera against leucocytes from 100 donors and detected a seemingly diallelic system of two leucocyte antigens which he called 4a and 4b (later known as HLA-Bw4 and HLA-Bw6 [8]), while Payne with collaborators in 1964 detected two leucocyte antigen LA1 and LA2 (later HLA-A1 and HLA-A2 ...
A cross-reaction test between potential donor cells and recipient serum seeks to detect presence of preformed anti-HLA antibodies in the potential recipient that recognize donor HLA molecules, so as to prevent hyperacute rejection. In normal circumstances, compatibility between HLA-A, -B, and -DR molecules is assessed.
HLA DR4 is correlated with the genesis of rheumatoid arthritis, type 1 diabetes mellitus, and pemphigus vulgaris. Fewer correlations exist with MHC class I molecules. The most notable and consistent is the association between HLA B27 and spondyloarthropathies like ankylosing spondylitis and reactive arthritis.
