Rheumatoid arthritis: Joint injury risk

Rheumatoid arthritis: Joint injury risk

Celine Haarhoff

Rheumatoid arthritis (RA) is a chronic autoimmune disease that affects the joints, causing inflammation, swelling, and pain. This condition can lead to joint damage and disability if not properly treated. RA is a genetic disease for many individuals, meaning their risk of developing it is influenced by their genes.


The genetics of RA is complex, with multiple genes contributing to an individual's risk of developing the condition. Among these are genes that are involved in the regulation of the immune system and immune response. Variations in genes that encode for immune response proteins may increase one's risk for autoimmune diseases such as RA. 

 

Genetic variations also contribute to the degree of joint damage RA patients are likely to suffer. In other words, if you suffer from RA, your genes also influence how severely you experience it or whether the condition causes minor or major damage to the joints. 

 

Symptoms of RA can vary from person to person, but common symptoms include joint pain, stiffness, and swelling. These symptoms often affect the small joints in the hands and feet but can also affect larger joints like the knees and hips. RA can also cause fatigue, weight loss, and fever. In some cases, RA can also affect other organs, such as the lungs, heart, and eyes.


If you have a family history of RA or are experiencing symptoms, a genetic test can help determine if you have a genetic predisposition to the condition. This test involves analyzing your DNA to identify genetic variants linked to RA. The test results can provide important information about your risk of developing the condition and guide your healthcare provider in developing a treatment plan.

 

Overall, a genetic test for RA can provide important information about an individual's risk of developing the condition and guide their healthcare provider in developing a personalized treatment plan. 


By identifying individuals at high risk for severe joint-damaging RA, we can screen for the condition and start treatment early. Early intervention can decrease the degree of joint damage and disability and improve the overall quality of life for individuals with this chronic autoimmune disease.
