What is SCN1A-Related Syndrome Syndrome?

SCN1A-related syndrome happens when there are changes to the SCN1A gene. These changes can keep the gene from working as it should.

SCN1A-related syndrome is also called Dravet Syndrome.

Key Role

The SCN1A gene produces a protein that sits in the surface of brain cells and allows sodium to enter the cell. This protein is important for brain cells to make and transmit signals between cells. The protein is essential for these brain cells to work properly.


Because the SCN1A gene is important in the development and function of brain
cells, many people who have SCN1A-related syndrome have:

  • Epilepsy
  • Developmental delay and/or intellectual disability
  • Autism spectrum disorder or autistic features
  • Movement problems
  • Concerns with sleep

How many people have SCN1A-related syndrome?

SCN1A-related syndrome occurs in 1 in 20,900 births. The first case of SCN1A- related syndrome was described in 2000. Scientists expect to find more people who have the syndrome as access to genetic testing improves.


Support Resources



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

We currently do not have any article summaries for SCN1A, but we add resources to our website as they become available.

The information available about SCN1A 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 SCN1A articles can be found here.

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