What gene change causes Kabuki syndrome?
A mutation, or change, in the genetic information of the KMT2D gene causes Kabuki syndrome. This gene is responsible for about 75% of the cases. Another gene recently identified (KDM6A) has been found in about 6-9% of individuals who do not have a KMT2D mutation. KMT2D makes a protein that helps to build a structure for storing genetic information. It also helps genes know when to turn on and turn off. This helps the body grow and develop normally. When there is an error in the KMT2D gene, the other genes cannot work correctly and development is abnormal. A genetic counselor can help to explain how genes work and their functions.
