Lupus is a chronic autoimmune disease that causes inflammation in organs and joints, affects movement and the skin, and causes fatigue. There is no cure for lupus now. 

However, a recent study published in Nature has identified DNA mutations in a gene that senses viral RNA as a cause of lupus, paving the way for the development of new treatments. This is the first time a TLR7 mutation has been shown to cause lupus, providing clear evidence of one way this disease can arise. There is hope!
