In this episode, we explore the truth behind the HLA-B27 gene and its connection to ankylosing spondylitis (AS). We break down common misconceptions, especially those circulating on social media, and explain why a positive or negative test result isn’t enough for a diagnosis. You’ll learn how misinterpretation of this gene — by both patients and doctors — can lead to misdiagnosis, and why a full clinical picture is essential for understanding AS.
