What is SMARCC2-related syndrome?
SMARCC2-related syndrome happens when there are changes to the SMARCC2 gene. These changes can keep the gene from working as it should.
SMARCC2-related syndrome is similar to other syndromes that are caused by related genetic pathways:
- Coffin-Siris syndrome, which is caused by changes in the genes ARID1A, ARID1B, SMARCA2, SMARCA4, SMARCB1, and SMARCE1.
- Nicolaides-Baraitser syndrome, which is caused by changes in the gene SMARCA2.
Key Role
SMARCC2 plays a key role in how the brain and body develop.
Symptoms
Many people who have SMARCC2-related syndrome have:
- Developmental delay and intellectual disability
- Speech challenges that may be severe
- Low muscle tone
- Feeding difficulties
- Behavioral concerns, such as autism
- Differences in physical appearance
How many people have SMARCC2-related syndrome?
As of 2019, about 15 people in the world with changes in the SMARCC2 gene had been described in the medical literature. The first case of SMARCC2related syndrome was described in 2009. Scientists expect to find more people who have the syndrome as access to genetic testing improves.

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.
There is currently no GeneReviews for SMARCC2.
Research Article Summaries
Below, we have included research articles about changes in the SMARCC2 gene. We hope you find this information helpful.
The information available about SMARCC2 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 SMARCC2 articles can be found here.
You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
