Below is a summary for the HIVEP2 gene observed in research publications. This is not meant to take the place of medical advice.

Download the latest quarterly report here. The goal of this report is to share up-to- date data contributed by families. The new report features information from the Children’s Sleep Habits Questionnaire (CSHQ). The CSHQ is a survey that you fill out on your dashboard.

What is HIVEP2-related syndrome?

HIVEP2-related syndrome happens when there are changes to the HIVEP2 gene. These changes can keep the gene from working as it should.

Key Role

The HIVEP2 gene plays a key role in the growth of the brain.


Because the HIVEP2 gene is important in the growth of the brain, many people who have HIVEP2-related syndrome have:

  • Intellectual disability
  • Behavior issues
  • Low muscle tone

Do people who have HIVEP2-related syndrome look different?

People who have HIVEP2-related syndrome may look different. Appearance can vary and can include these features:

  • High forehead
  • Wide-set eyes

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 is currently no GeneReviews for HIVEP2.

Research Article Summaries

Below, we have summarized research articles about changes in the HIVEP2 gene. We hope you find this information helpful.

The information available about HIVEP2 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 HIVEP2 articles can be found here.
