Researchers examined DNA from over seven thousand people with ankylosing spondylitis and more than a million others without the condition. They used data from large health groups to find genetic markers connected to the disease. This approach helps scientists see patterns that are hard to spot in smaller groups.
The team found thirty important genetic spots and over twenty-six thousand smaller changes linked to the illness. These changes are found in areas of DNA that control how our immune system works. Some of these spots are shared with other conditions like psoriasis and inflammatory bowel disease.
Scientists also tested specific genes in lab cells to see how they behave. They found that turning off certain genes changed how immune cells act. This supports the idea that these genes play a real role in causing the disease.
While this study does not offer a cure, it gives doctors new ideas for future research. It helps them focus on the immune system parts that cause the problem. More work is needed to turn these ideas into new treatments for patients.
