By Mayo Clinic staff- Your sex. More males than females have the disease.
- Your age. Onset generally occurs between late adolescence and age 40.
- Your heredity. Genetics may play a role in the development of ankylosing spondylitis. In fact, the majority of people with this condition have the HLA-B27 gene. Having this gene doesn't mean that you'll acquire ankylosing spondylitis — many people without ankylosing spondylitis have this gene — but it may make you more susceptible to the disease. If you have ankylosing spondylitis, and you pass the HLA-B27 gene on to your child, there's only a one in five chance your child will develop ankylosing spondylitis.
