What are the genetic changes related to Coffin-Lowry syndrome ?
Mutations in the RPS6KA3 gene cause Coffin-Lowry syndrome. This gene provides instructions for making a protein that is involved in signaling within cells. Researchers believe that this protein helps control the activity of other genes and plays an important role in the brain. The protein is involved in cell signaling pathways that are required for learning, the formation of long-term memories, and the survival of nerve cells. Gene mutations result in the production of little or no RPS6KA3 protein, but it is unclear how a lack of this protein causes the signs and symptoms of Coffin-Lowry syndrome.  Some people with the features of Coffin-Lowry syndrome do not have identified mutations in the RPS6KA3 gene. In these cases, the cause of the condition is unknown.
