What is CHD2 -related syndrome?

CHD2 -related syndrome happens when there are changes to the CHD2 gene. These changes can keep the gene from working as it should.

Key Role

The CHD2 gene plays a key role in the brain and body.

Symptoms

Many people who have CHD2 -related syndrome have:

Developmental delay, intellectual disability
Autism spectrum disorder or symptoms of autism
Epilepsy that starts at a young age
Behavioral challenges
Short height and a small head

GeneReviews

GeneReviews are a great resource to bring to your child’s clinicians. These publications provide a summary of current research on genetic conditions and information on ongoing care.

Research Article Summaries

Below, we have summarized research articles about changes in the CHD2 gene. We hope you find this information helpful.

The information available about CHD2 is limited, and families and doctors share a critical need for more information. As we learn more from children who have a change in this gene, we expect this 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 CHD2 articles can be found here.

You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
