Your QuestionMy son suffers from Rubinstein-Taybi syndrome. Over the past year he has developed tremors affecting both upper extremities. I am wondering if there is a known cause associated with the disorder. My research seems to indicate there may be but I cannot find anything definitive.
We have identified the following information that we hope you find helpful. If you still have questions, please contact us.
Rubinstein-Taybi syndrome may be caused by a mutation in the CREBBP or EP300 gene, or as the result of a very small deletion (microdeletion) of genetic material from the short (p) arm of chromosome 16. In some affected people, the cause is unknown. Researchers believe that these cases are due to mutations in other genes that have not yet been identified.
