Ru·bin·stein-Tay·bi syn·drome

(rū'bĭn-stīn tā'bē),
mental retardation, broad thumb and great toe, antimongoloid slant to the eyes, thin and beaked nose, microcephaly, prominent forehead, low-set ears, high arched palate, and cardiac anomaly; a submicroscopic chromosomal defect may be causative, but evidence suggests that this syndrome is due to mutation in the gene encoding transcriptional coactivator CREB-binding protein on chromosome 16p.

Rubinstein-Taybi syndrome

[ro̅o̅′binstīn tā′bē]
Etymology: Jack Herbert Rubinstein, American pediatrician, 1925-2006; Hooshang Taybi, American radiologist, 1919-2006
a congenital condition characterized by mental and motor retardation; broad thumbs and great toes; short stature; characteristic facies, including high-arched palate and straight or beaked nose; various eye abnormalities; pulmonary stenosis; keloid formation in surgical scars; large foramen magnum; and abnormalities of the vertebrae and sternum.

CREBBP

A gene on chromosome 16p13.3 that encodes a ubiquitously expressed protein involved in the transcriptional coactivation of various transcription factors. CREBBP acts as a scaffold to stabilise additional protein interactions with the transcription complex; it has intrinsic histone acetyltransferase activity, and acetylates both histone and non-histone proteins.

Molecular pathology
CREBBP mutations cause Rubinstein-Taybi syndrome (RTS); chromosomal translocations of CREBBP are associated with acute myeloid leukaemia.
