17q12 Duplication

Below is a summary for the 17q12 duplication observed in research publications. This is not meant to take the place of medical advice. The full gene guide, which includes more information, coming soon.

What is chromosome 17q12 duplication syndrome?

Chromosome 17q12 duplication syndrome can have variable effects on the development of communication, social, and learning skills. It can affect how a person acts or interacts with others. Many people who have 17q12 duplication syndrome have:

  • Intellectual disability
  • Speech delay
  • Seizures

Do people who have 17q12-duplication syndrome look different?

Some people who have 17q12 duplication syndrome have minor changes in their appearance, such as a flat forehead, a low hairline, thick eyebrows, and thick lips.

Research Article Summaries

We currently do not have any article summaries for 17q12 Duplication, but we add resources to our website as they become available.

The information available about 17q12 Duplication 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 17q12 duplication articles can be found here.

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