What is 7q11.23 duplication syndrome?

7q11.23 duplication syndrome happens when a person has an extra piece of chromosome 7, one of the body’s 46 chromosomes. Chromosomes are structures in our cells that house our genes. The extra piece can affect learning and how the body develops.

Key Role

The 7q11.23 duplication region plays a role in brain development.

Symptoms

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
  • Behavioral issues, including anxiety, attention-deficit/hyperactivity disorder (ADHD), and autism
  • Developmental delay
  • Intellectual disability
  • Lower than average muscle tone
  • Seizures
  • Heart issues
  • Gastrointestinal issues
  • Vision and hearing issues

How many people have 7q11.23 duplication syndrome?

About 1 in 7,500 to 1 in 20,000 people have 7q11.23 duplication syndrome. The first case was described in 2007. As of 2024, at least 204 people with 7q11.23 duplication syndrome have been identified in medical research.

Research Article Summaries

We currently do not have any article summaries for 7q11.23 Duplication, but we add resources to our website as they become available. The information available about 7q11.23 Duplication is limited, and families and doctors share a critical need for more information. As we learn more from children who have this gene change, we expect our list of resources and information to grow. Full versions of published research articles can be found on PubMed. PubMed is a National Institutes of Health (NIH) online database that is free. It has a collection of both medical and scientific research articles. A PubMed search for 7q11.23 Duplication articles can be found here. You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
