What is TLK2-related syndrome?

TLK2-related syndrome happens when there are changes to the TLK2 gene. These changes can keep the gene from working as it should.

Key Role 

The TLK2 gene plays a key role in brain growth.

Symptoms

Because the TLK2 gene is important in the development and function of brain cells, many people who have TLK2-related syndrome have:

  • Developmental delay
  • Behavior issues
  • Gastrointestinal issues

How many people have TLK2-related syndrome?

As of 2020, about 40 people in the world with changes in the TLK2 gene had been described in the medical literature. The first case of TLK2related syndrome was described in 2016. 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 TLK2.

Research Article Summaries

We currently do not have any article summaries for TLK2, but we add resources to our website as they become available.

The information available about TLK2 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 TLK2 articles can be found here.

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