Rubinstein-Taybi syndrome is a rare condition, affecting about 1 in 125,000 people. Most persons with RTS have a defect in a gene that leads to an abnormal CREB binding protein (CREBBP).
About 10% of patients, typically with more severe problems, are missing the gene entirely and do not make any CREBBP.
Most cases are sporadic and likely due to a new mutation occurring during fetal development, which was not passed on by either parent. However, in some cases, it is inherited in an autosomal dominant fashion, which means that if one parent passes on the defective gene, the child will be affected.
