CHARGE SYNDROME CLASSIFICATION, ETIOLOGY

Charge syndrome  CS is a genetic condition. It is caused by a change or variant in at least one gene. However, we do not find a genetic change in all individuals with features of CS. Most of the time, the genetic change is present in the child but not in the parents. This means that it is a new change in the individual with CS and not inherited. These changes occur with each pregnancy. Because they happen with each pregnancy, it is only important for a person if they happen in a gene that can cause a medical condition. These are not caused by anything that a parent does or does not do.
