A variation of the HLA-B gene called HLA-B27 increases the risk of developing ankylosing spondylitis. Although many people with ankylosing spondylitis have the HLA-B27 variation, most people with this version of the HLA-B gene never develop the disorder.

What chromosome is affected in ankylosing spondylitis?
