https://www.youtube.com/watch?v=g02RnGXCXrQ Many human diseases are due to faulty genes in our DNA. This informative video from the Khan Academy shared in April 2014 discusses genetic mutations. The simple sketches explain how mutations occur in cells and proteins, and what happens when a gene mutates. Researchers use blood tests to identify DNA changes and improve diagnosis in IBD patients. Find out more. The film describes how a person could inherit a genetic mutation or how mutations can occur spontaneously at any point in a person's life and trigger an autoimmune disease such as Crohn's disease or ulcerative colitis. Understanding exactly why these genes mutate could be a factor in determining a cure for IBD or providing better treatments. A protein found vital in controlling inflammation in Crohn's disease could be a possible therapeutic target for IBD. IBD News Today is strictly a news and information website about the disease.
