Rubinstein-Taybi Syndrome
Rubinstein-Taybi syndrome (RTS) is a syndrome characterized by broad thumbs and toes, short stature, distinctive facial features, and varying degrees of intellectual disability. The syndrome may be caused by a mutation in the CREBBP or EP300 gene, or as the result of a very small loss (microdeletion) of genetic material from the short (p) arm of chromosome 16. In some people with RTS, the cause is unknown. While RTS can be inherited in an autosomal dominant manner, most cases result from a new (de novo) mutation in the responsible gene and are not inherited from a parent. Treatment is symptomatic and supportive.
