Normal Function
The SOX11 gene provides instructions for making a protein that plays a critical role in the development of the brain and nerve cells (neurons). This protein is a transcription factor, which means it attaches (binds) to specific regions of DNA and coordinates with other proteins to turn on particular genes.
Studies suggest that the SOX11 protein may also be able to regulate the activity of genes involved in brain and nerve cell development through a different process known as chromatin remodeling. Chromatin is the network of DNA and protein that packages DNA into chromosomes. The structure of chromatin can be changed (remodeled) to alter how tightly regions of DNA are packaged. Chromatin remodeling is one way gene expression is regulated during development; when DNA is tightly packed, gene expression is often lower than when DNA is loosely packed.
The activity (expression) of the SOX11 gene is controlled by chromatin remodeling by special protein groups called SWI/SNF complexes.
Health Conditions Related to Genetic Changes
Coffin-Siris syndrome
At least 14 variants (also known as mutations) in the SOX11 gene have been found to cause Coffin-Siris syndrome. This condition is characterized by intellectual disability, abnormalities of the fifth (pinky) fingers or toes, and characteristic facial features that are described as coarse. Most SOX11 gene variants involved in Coffin-Siris syndrome alter the SOX11 protein or prevent its production. These changes reduce the ability of the SOX11 protein to regulate the activity of genes, including those important for development of the brain and nerve cells. Altered gene activity can disrupt development of the brain and other tissues and organs, which could explain the diverse signs and symptoms of Coffin-Siris syndrome.
