7q11.23 duplication syndrome can affect communication, social, and learning skills. People who have 7q11.23 duplication syndrome may have:

  • Distinct facial features
  • Speech delay
  • Behavior issues, including anxiety, attention deficit hyperactivity disorder, and autism
  • Developmental delay

What causes 7q11.23 duplication syndrome?

7q11.23 duplication syndrome happens when someone has an extra piece of chromosome 7, one of the body’s 46 chromosomes. Chromosomes are structures in our cells that house our genes.

Do all people who have 7q11.23 duplication syndrome have symptoms?

Not necessarily. Some people do not have any symptoms. Some people may not learn that they have this genetic change until it is found in their children.
