What causes Kawasaki syndrome ?
What genes are related to Kawasaki syndrome? A variation in the ITPKC gene has been associated with an increased risk of developing Kawasaki syndrome. This gene provides instructions for making an enzyme called inositol 1,4,5-triphosphate 3-kinase C. This enzyme helps limit the activity of immune system cells called T cells, which identify foreign substances and defend the body against infection. Reducing the activity of T cells when appropriate prevents the overproduction of immune proteins called cytokines that lead to inflammation and can, when present in large quantities, can cause tissue damage. Researchers believe that variations in the ITPKC gene may interfere with the body's ability to reduce T cell activity, leading to inflammation that damages blood vessels and results in the symptoms of this disease. It is likely that other factors, including changes in additional genes, also influence the development of this complex disorder. What causes Kawasaki syndrome? The cause of Kawasaki syndrome isn't known. The body's response to a virus or infection combined with genetic factors may cause the disease. However, no specific virus or infection has been found, and the role of genetics is not well understood. Kawasaki syndrome is not contagious; it can't be passed from one child to another.
