Rubinstein-Taybi syndrome (RSTS)

Rubinstein-Taybi Syndrome is a congenital disorder characterized by broad thumbs and great toes, typical facies (microcephaly, small mouth, short upper and pouting lower lip, downslanting palpebral fissures, heavy eyebrows, long lashes, beaked nose, and high narrow palate), micrognathia, hirsutism, and low anterior hairline. Patients exhibit growth retardation, psychomotor developmental delay and cognitive disability. Ocular problems (including strabismus, cataract, glaucoma), congenital heart defects, feeding problems, hemangiomas, keloid formation, finger pads, increased risk of tumors (particularly of tissues derived from the neural crest), abnormalities of the patella, and seizures are seen in varying percentage of affected individuals.
