Anti-CCP antibodies are most associated with which disease?

Explanation:
Anti-CCP antibodies are highly specific for rheumatoid arthritis and are often detectable early in the disease, sometimes before joint symptoms appear. They target citrullinated proteins produced during inflammatory processes in the joints, and their presence is associated with a higher risk of erosive, more aggressive RA. This biomarker is much less common in other autoimmune conditions such as systemic lupus erythematosus, Sjögren syndrome, or ankylosing spondylitis, where different antibodies or clinical features are more typical. Because of its strong specificity for RA, anti-CCP antibodies are most closely linked to rheumatoid arthritis.
