Lottie Peppers on 27 Mar 16Researchers in a new study at the University of Edinburgh have honed in on five of 89 independent variations in human genetics that are believed to be responsible for autoimmune conditions, from celiac disease and multiple sclerosis to rheumatoid arthritis and asthma. Understanding how these mechanisms work could help scientists to develop new treatments. The team found that a mutation in the ADAR1 gene causes a defect in an "alarm system" in cells that normally protects the body from viruses and other infections by triggering the body's immune system to fight.
