What is HNRNPH2-related neurodevelopmental disorder?

HNRNPH2-related neurodevelopmental disorder happens when there are changes in the HNRNPH2 gene. These changes can keep the gene from working as it should.

HNRNPH2-related neurodevelopmental disorder is also called Bain type of X-linked syndromic intellectual disability.

Key Role

The HNRNPH2 gene plays an important role in processing messenger RNA, or mRNA, which cells use to make proteins.

Symptoms

Because the HNRNPH2 gene is important for many parts of the body, some people may have:

Intellectual disability
Seizures
Speech and language difficulties
Autism
Abnormal muscle tone
Movement issues
Attention deficit hyperactivity disorder, or ADHD
Aggression
Anxiety
Feeding issues and constipation
Brain changes seen on magnetic resonance imaging (MRI) for some people

Do people who have HNRNPH2-related neurodevelopmental disorder look different?

People who have HNRNPH2-related neurodevelopmental disorder may look different. Appearance can vary and can include some but not all of these features:

Short height
Difficulty gaining weight
Smaller than average head size
Wide-set eyes
Full and wide lips
Sideways curvature of the spine, also called scoliosis

How many people have HNRNPH2-related neurodevelopmental disorder?

As of 2022, about 49 people in the world with HNRNPH2-related neurodevelopmental disorder have been described in medical research.

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. Check out the GeneReviews for HNRNPH2.

Research Article Summaries

Below, we have summarized research articles about changes in the HNRNPH2 gene. We hope you find this information helpful. The information available about HNRNPH2 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 HNRNPH2 articles can be found here. You can also visit the Simons Foundation’s SFARI Gene website to see information for researchers about this gene.
