WebStudies have shown factors such as genetic background gene called ( HLA-B27), microbial infection, endocrinal abnormalities and immune reaction related to the occurrence of AS. [14] In addition, a direct relationship between AS and the major histocompatibility human leukocyte antigen (HLA)-B27 has also been determined. WebAnkylosing spondylitis: A version of the HLA-B gene called HLA-B27 increases the risk of developing ankylosing spondylitis. It is uncertain how HLA-B27 causes this increased risk. Researchers speculate that HLA-B27 may abnormally display to the immune system peptides that trigger arthritis.
WebThe precise etiology of AS remains mostly unknown, though heritability is frequently cited as a significant contributor. Major histocompatibility alleles, particularly HLA-B27, may account for up to one-third of the genetic effect. Other MHC alleles that may play a minor role in AS heritability include HLA-B60 and HLA-DR1.
