VAMP2-related syndrome is also called neurodevelopmental disorder with hypotonia and autistic features with or without hyperkinetic movements. For this webpage, we will be using the name VAMP2-related syndrome to encompass the wide range of variants observed in the people identified.

What is VAMP2-related syndrome?

VAMP2-related syndrome happens when there are changes in the VAMP2 gene. These changes can keep the gene from working as it should.

Key Role

The VAMP2 gene plays a role in cell communication in the brain.


Because the VAMP2 gene is important in brain development and function, many people who have VAMP2-related syndrome have:

  • Developmental delay
  • Intellectual disability
  • Delayed speech or are non-verbal
  • Delayed sitting and walking
  • Shaky movement or walking
  • Autism

How many people have VAMP2-related syndrome?

As of 2024, at least 12 people with VAMP2-related syndrome have been identified in medical research.

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.

There are currently no GeneReviews for VAMP2.


Research Articles and References

Below, we have summarized research articles about changes in the VAMP2 gene. We hope you find this information helpful.

The information available about VAMP2 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 VAMP2 articles can be found here.

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