ANKRD11

Below is a summary for the ANKRD11 gene observed in research publications. This is not meant to take the place of medical advice.

What is ANKRD11-related syndrome?

ANKRD11-related syndrome happens when there are changes to the ANKRD11 gene or when a piece of DNA that includes the ANKRD11 gene is missing. These changes can keep the gene from working as it should. The syndrome is also known as KBG syndrome.

Key Role

The ANKRD11 gene plays a key role in the growth of the brain and bones. It’s also important for the growth of new cells and for connections between brain cells.

Symptoms

Because the ANKRD11 gene is important in the development and function of brain cells, many people who have ANKRD11-related syndrome have:

  • Intellectual disability and developmental delay
  • Behavioral issues
  • Large upper front teeth, also called macrodontia, and other unusual facial features
  • Skeletal differences, such as a curved spine and shortened fingers, shortened toes, or both

Do people who have ANKRD11-related syndrome look different?

People who have ANKRD11-related syndrome may look different. Appearance can vary and can include some but not all of these features:

  • Triangular shaped face and short head, also called brachycephaly
  • Prominent bridge of nose, bulbous nose, forward-facing nostrils
  • Broad or bushy eyebrows, eyebrows that meet at the center of the forehead, widely spaced eyes
  • Long area between nose and lips, thin upper lip
  • Ears that stick out

Research Article Summaries

Below, we have summarized research articles about changes in the ANKRD11 gene. We hope you find this information helpful.

The information available about ANKRD11 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.

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