RNA-dominant diseases, also known as RNA-mediated diseases, are those in which RNA molecules play a key role in disease pathogenesis. They are often caused by genetic mutations that affect the way RNA functions in cells. Other synonyms for RNA-dominant disease include RNA disorders, RNA-mediated disorders, and RNA-related diseases. These disorders can impact a wide range of bodily functions, with symptoms ranging from mild to severe. Some examples of RNA-mediated diseases include Huntington's disease, myotonic dystrophy, and fragile X syndrome. Understanding the role of RNA in these diseases is crucial to developing effective treatments and potential cures.
